Why type of joint is the shoulder joint?

Answer 1

The shoulder joint is also called the Glenohumeral joint. It is classified as a Synovial Ball-and-Socket Joint. This type of joint exhibits a great amount of mobility, while sacrificing stability. It is made up of the convex humoral head and concave glenoid cavity of the scapula. The arthrokinematics of the joint consist of movements in the sagittal plane (flexion/extension), frontal plane (adduction/abduction), and transverse plane (internal/external rotation, horizontal adduction/abduction). Hope this helps, reach out with any question if further clarification or explanation is needed!

Answer 2

The shoulder is a ball and socket joint which allows the shoulder to have an increased range of mobility

Answer 3

Hello!

The shoulder joint is a ball-and-socket joint, where the head of the humerus, the bone of the upper arm, is round from the top and fits into the shallow socket of the scapula called the glenoid cavity. The Hip joint is another example of a ball/socket joint in humans. Hope this helps, feel free to reach out with more questions!
