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.

Answer 1

Answer:

the answer is D The cup shape of the socket allows for nearly circular motion​

Explanation:

Ball-and-socket joints possess a rounded, ball-like end of one bone fitting into a cup-like socket of another bone. This organization allows the greatest range of motion, as all movement types are possible in all directions.

Answer 2

Answer :

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

Explanation :

• The socket's cup form allows for almost circular rotation. In vertebrate anatomy, a ball-and-socket joint, also known as a spheroidal joint, is a joint in which a bone's spherical surface glides within a depression on another bone, enabling greater flexibility of movement than any other type of joint.

• A rounded, ball-like end of one bone fits into a cup-like socket of another bone in a ball-and-socket joint. Because all movement types are feasible in all directions, this structure allows for the largest range of motion.
