Human Anatomy (multiple choice) (introductory question)

Question

The difference between a tubercle and a trochanter is that

a) The tubercle is where two bones come together, a trochanter is an area of muscle attachment
b) A tubercle is where muscle tendons attach to bones, a trochanter is where ligaments anchor two bones together.
c) They are essentially the same thing except the tubercles are found on the lower extremity while trochanters are found on the upper extremity.
d) They are almost identical in definition, however tubercles are smaller and the trochanter is more blunt and less rounded.

Answer 1

The answer should be (D). For (A), the word "condyle" would better describe where two bones meet and the second part seems to describe a "process." (B) can be ruled out because the femoral trochanters attach to tendons, not ligaments. (C) can be ruled out because there are tubercles on the humerus (upper extremity) and trochanters on the femur (lower extremity).

This link better shows the relationship. Trochanteric is then top part of the femur while tubercle is the rounded bottom part of the femur.
