Condyloid joints allow movement in how many planes?

Condyloid joints allow movement in how many planes?

• A. One plane
• B. Two planes
• C. Three planes
• D. No movement

Answer: (B)

Condyloid joints are biaxial synovial joints, meaning they allow movement in two directions. Their oval condyle fits into an elliptical cavity, so you can bend and straighten the joint (flexion and extension) in one plane, and move it side to side (abduction and adduction) in another plane. This combination lets you perform circumduction as a mix of those two movements, but rotation around the long axis is limited. So the joint moves in two planes.
