Question

21 which type of joint has oval shaped ends of one bone that articulates with the elliptical cavity of another
a condyloid
b gliding
c saddle
d hinge

Explanation:

• Condyloid joints: These joints have an oval - shaped end of one bone that fits into an elliptical cavity of another bone. They allow movement in two planes (flexion - extension and abduction - adduction).
• Gliding joints: Bones in gliding joints have flat or slightly curved surfaces that glide over each other.
• Saddle joints: Have a saddle - like shape where one bone fits into the complementary saddle - shaped surface of another bone.
• Hinge joints: Allow movement similar to a door hinge, mainly in one plane (flexion - extension).

Answer:

A. Condyloid
