Question

which of the following statements best explains why ball-and-socket joints have the greatest range of motion? a. the contours of the two bones allow for maximum movement. b. the even planes of the bones allow full rotation. c. the two matching surfaces allow for movement in multiple directions. d. the cup shape of the socket allows for nearly circular motion. please select the best answer from the choices provided. a b c d

Explanation:

Ball-and-socket joints have a cup-shaped socket that encloses a rounded ball, enabling movement in multiple planes (flexion, extension, abduction, adduction, rotation), which is nearly circular. This structure provides the greatest range of motion.

Answer:

D. The cup shape of the socket allows for nearly circular motion.
