Are you confused about how the smooth muscle of the gastrointestinal system is regulated. Many students struggle with the fact that muscarinic receptors and purinergic receptors both stimulate phospholipase but lead to opposite effects on smooth muscle contraction. I have organized information into a slide show to help students study this topic. Regulation of GI Motility
I have come up with two explanations that help me understand the way purinergic receptors can decrease motility through activation of phospholipase. One aspect is that acetylcholine inhibits protein kinase A (PKA). Phosphorylation of Ca-actiated potassium channels by PKA increases their sensitive to calcium sparks. Also the purinergic receptors are located on a separate cell called the PDGFR+ fibroblast like cell. Hyperpolarizing currents resulting from activation of potassium channels can spread through GAP junctions from the PDGFR+ fibroblast like cells into the smooth muscle...
One summer I was ambitious and signed up for a condensed Anatomy & Physiology II course. Having just completed Anatomy & Physiology I and Microbiology during the spring semester, I thought just taking one college course over the summer would be a piece of cake. How wrong I was! Learning the major systems of the human body in a full 16 week semester can be challenging for most students. Fortunately, our professor believed in assigning essay styled lab reports. Writing about new and more complex topics is challenging!
A few weeks into the condensed summer session I realized I would not achieve the A I wanted in A & P II
without a full commitment to spend every waking moment studying. My professor made it clear to the class that he was not going to grade us any easier just because we chose to take the 'short course.' I vividly recall him announcing during lecture that the endocrine system was probably the toughest...
The most obvious answer is cost. If a tutor charges the same rate for one or four students, it becomes cheaper per hour as you increase students and share the costs with other families. It is often believed a tutor is best when working 1:1 with a student. In some instances it is well worth the time and money to have 1:1 tutoring and sometimes it is appropriate for students to study and do school work in small groups.
What is not obvious is the dynamics of small group tutoring. In a variety of circumstances it is invaluable for students to learn how to study “what needs to be studied”. The acts of independence and self regulating behavior have far reaching benefits.
Groups need to learn to share and take turns. This seems simple and yet there is the underlying tendency to allow the ‘smart one’ in the group to carry the burden of work. Assuming each student is in the class and has a different point of view/observation about what is happening in class, they should share their...
Although I do not own a TV (and have not for pretty much all of my adult life), I occasionally allow myself to partake in mind numbing and will watch past episodes of a show via Netflix. It would not have occurred to me I could learn something helpful about studying and yet I did!
Although I did not realize it at the time, Bones (cerebral/quirky weekly drama about a forensic anthropologist played by Emily Deshanel) and later Grey's Anatomy (medical drama with some elements of non-fiction starring Patrick Dempsey and Sandra Oh), subtly helped me understand how to become a better connoisseur of studying anatomy and physiology. It was not until recently, while working with a pre-nursing school student, I put the pieces together.
Anyone who works with the body (living or dead) must create their own 'GPS' system for navigating the body as no two are exactly alike. Each bone, muscle, system and tissue (sometimes even cells) are just slightly different. There is a range of normal...
Since I am new to the site, I would like to tell you a little bit about me. I worked as a Supplemental Instruction leader for an Anatomy and Physiology course for over two years. This position is given to those who have taken the course and received a high grade and who have participated in training regarding tutoring styles and study skills. I held three sessions per week which were optional for the students. Anywhere from one to one hundred students would attend depending on the difficultly of the current material or whether or not they had an exam in the near future. I was required to submit lesson plans and create mock exams/review sessions. I love working in groups or one-on-one. I am majoring in Biology and Psychology with a minor in Biochemistry. I have finished all courses required for my minor (plus two extra). I am almost done with my Biology degree. I have taken basic psychology classes as well as advanced ones such as Biopsychology, Behavioral Neuroscience, Statistics and...
I have noticed a number of students in this area struggling with Algebra I and Algebra II. The students are at different levels of their educational process from High School to adult students re-entering the collegiate experience. In my experience having taught upper division sciences is that students who find that they have deficiencies in their lower level math skills, generally, 6-8th grade math, don't 'see' these deficiencies show up until they move into upper division college programs where more critical, cross-disciplinary thinking is required of them.
Here is the problem. There is an aspiration to be a science teacher, for instance, or a doctor of some sort. Because a math deficiency was not addressed earlier, they struggle in Chemistry or Cell Biology. The assumption on the part of the faculty is that the poor grade reflect ineptitude with a given subject. Hence, it is presumed that the student is not 'able to compete' for careers in these kinds of careers. The student,...
Let me know!
If you are in the preliminary stage working toward applying for a nursing program, I would love to meet you! I know it is hard work taking the courses you are studying and completing all requirements needed to make your application. Since 2010 I've studied biology, chemistry, microbiology, anatomy and physiology, in depth. These are not the easiest subjects to learn, especially if you are returning to college after taking time off to raise a family or pursue a career path in a different field. As a non-traditional student, I spent many late nights in Denny's drinking my vanilla lattes while reviewing difficult concepts in chemistry, anatomy and physiology.
I returned to college after decades of being out of school. With my laptop and Pearson's Anatomy & Physiology, Mastering Chemistry and Cengage OWL's online chemistry resources those long nights at Denny's paid off. I began to grasp concepts that were foreign to me through the use of many computer programs, even when it was...
As you may know, I am a big fan of the well-known author and brain specialist, Dr. Daniel Amen. He mentions in several of his books that Physical Exercise is good for the brain. I have read of research studies that showed a clear correlation between IMPROVEMENT in students' test scores in math and science, and their level of physical activity (for example, when math class followed PE class, the students had significantly higher scores). Maybe we should schedule PE before all math classes in our schools. What do you think about that idea?
This morning I read an online article on the myhealthnewsdaily site, entitled "6 Foods That Are Good for Your Brain," and another article about how Physical Exercise helps maintain healthy brain in older adults too. The second article, "For a Healthy Brain, Physical Exercise Trumps Mental Workout" was found under Yahoo News.
The remainder of this note is quoted from that article:
Regular physical exercise appears to...
The moans and groans are audible! "Why do I have to do homework??"
Let me tell you why I assign additional work outside of a tutoring session ... It is my job to be sure that you are able to apply and integrate the materials we cover in addition to being able to absorb facts and information. Sometimes what I call 'homework' is nothing more than finding an article about the topic we are covering at the time and being ready to discuss it with me using the terms and concepts we have been going over. Sometimes it may be a question I want you to be thinking about over the next few days or week, and be able to give me an answer or argument (either for or against) a particular issue when we next meet. These assignments are not unreasonable in length or duration, and will provide both of us an indicator of how well you have absorbed the subject material.
When I tutor people especially in the more challenging science courses like Microbiology and Anatomy and Physiology I see students just memorizing and not understanding to overall picture. Especially in Microbiology where you have to learn the make up of different viruses and bacterial cells then use that information to see how that antibiotic works. What I found to work best is to ask why to every question. For example gram negatives microbes have a LPS layer on the outside. Now why is that important? When this breaks down it can cause septic shock in the patient. This is important information that if you can create connection it is easy to remember, and you can actually think about problem, not just regurgitating information I see way to often. Hope this can help some people the way it helped me, and some of my classmates I taught this process to.
The philosophy of teaching I have embraced in thirty years of teaching medical students and college students is based on the belief that learning is student centered and that students need to be equal partners in the learning process. There must be present, a student mentor relationship of trust. There should, however, always be an authoritative presence in the mentor. This leadership should be omnipresent, whether in the classroom, tutorship, or online. The mentoring teacher’s role involves using his expertise to place necessary resources in the hands of the student and to train him to be not just knowledgeable in his chosen fields of study, but to become an expert at resourcefulness and seek the role of “teacher" himself. It is here where leadership is taught through example.
Now that the majority of teaching is performed on an online forum, students now know that the teacher’s role in the online classroom is to be a facilitator, in addition to being a provider of information...
I'm new to this site and can't wait to help you. Got questions? I got answers! Whether you need some simple study skills and techniques or if you have very specific problems in a subject, I can help. Let me show you how all these subjects work together and are not isolated disciplines that you're never going to use. I'll show you the relevance of each subject and how they're all integrated. Learning is so much fun when you understand why you need to know.
Nursing school can be tough! If you are having difficulty or would like assistance with your studies, please contact me. I have been a registered nurse for 17 years and will graduate this semester with my BSN. I have experience in education as well and have a heart for teaching. I would love to work with you to help you succeed in this program.
I wish everyone the very best for the new year and happy learning!
My emerging tutoring passion is assisting ESL college students with their coursework. Most of them must also hold full-time jobs to support themselves and often their families as well. Many require online courses to get college educations. They could not earn a college degree any other way.
Do textbook publishing companies realize how much cultural bias is written into their online ancillary (supplemental) materials? Do teachers of online college courses realize how hopeless these students feel about merely passing a class when their grades depend on online multiple-choice exams consisting of 60 items to be completed in 60 minutes (60 in 60), for example? This may be a subtle form of cultural bias, but bias it is.
Frankly, as a native speaker of American English with a master’s degree in journalism from University of Wisconsin—Madison, I’m not sure I could pass a 60 in 60 exam. I would like to challenge the instructors who teach these online courses and college administrators...
Tutoring is never easy. But if I had to describe it, I would say its a session where you and a student sit down and learn together. Whether it be learning about each other or the material, it's all a part of the learning process. But going through school I've noticed that a lot of teachers now a days don't work with all the learning styles possible which makes it hard for students to learn.
So my advice to everyone who is tutoring, or even learning--Discover what yours and your students learning style is. Students, take a test and discover what learning style you are. Are you more of a visual learner? i.e. power points, videos, pictures, etc. or an audio learner? i.e. lectures, repeating notes out loud to yourself/friend, etc. or are you a kinesthetic learner? i.e. work with your hands, reviewing notes, etc.
Whatever style you may be (which you can be more than one), talk about it with your tutor. How can this style help you inside and outside of class? How can you make your...
Mi roja amor, mi sexy sangre, the body’s nectar
Beso a beso, I express to you my love in this letter –
Through I may be the heart; you are my corazon,
Mi casa es tu casa – when I hold you, we are home.
I keep the beat for this music of movement, de vida
Everything is alive because of you, mi querida
Circling the body, you give all the cells what they need
Nutrients, oxygen – mi plena mujer – how you bleed!
Veins have carried you to the eyes, muscles, the brain
With valves so strong, pushing against gravity’s strain.
Venous highways become streets, then finally a dirt road
These are the capillaries, where your nutrients unload
And when you have nothing more to give, sin dulce
The great vena cava vein brings you back my way
Into my heart you arrive; you’re blue, mis azules
My right atrium welcomes you as a special guest
Then, like lightning, my heart’s electricity shoots
Sending you through the tricuspid valve routes
Happy New Year! Are you ready for the new semester? No matter where you are in your education, first semester in college, or headed into that last one before graduation, being properly prepared will make all the difference!
1. Meet with an advisor and enroll as early as possible.
2. Get your books as soon as you can. Read through the table of contents and flip through he book to get an idea of what the course material will look like.
3. Know your schedule. Will you need to get up earlier then you are now? Now is a good time to start getting in a morning routine.
4. Get a planner (or use the calendar in your phone) to organize your schedule. This will help reduce cramming and over scheduling your time. Be sure to block out needed time for homework. I fill in all of my quizzes, exams, and reports due as soon as I know of them.
5. Get plenty of sleep, water, and good food. Healthy snacks will help stabilize your energy levels and give you needed brain food...
My name is Casey. I am a Registered Nurse in Spokane, Washington, and while I am new to this environment, I have been tutoring for the last four years. I am proficient at tutoring math and science, though I am not necessarily limited to those areas. I am also skilled at teaching study skills and organization, which can help students in any subject. I am willing to tutor students of all ages, and I relate well with child, adolescent, and adult students alike.
I believe that tutoring is a team effort in which the tutor and student work together to reach predetermined goals. The tutor facilitates learning by helping students to understand what learning style works best for them, and through teaching students how to organize their learning process. The student applies class content to the learning techniques, and the tutor helps the student to better understand concepts. My goal is to help students to become independent learners so that they can succeed in and...
I am finally winding down the summer this week, with most of my students having taken their final exams last week. Subjects I tutored during the second summer session:
Best of luck to all of my students! You have all worked hard and I hope you all get the grades that you were hoping for. Looking forward to a busy fall semester!
