Question

What is true of all these joints: tibiofemoral,hip,glenohumeral,and humeroulnar? They are all
A) freely movable.
B) ball and socket.
C) restricted to the axial skeleton.
D) restricted to the upper extremities.

Accepted Answer

All of these joints are freely movable, meaning they have a wide range of motion. The tibiofemoral joint is in the knee, the hip joint is in the pelvis, the glenohumeral joint is in the shoulder, and the humeroulnar joint is in the elbow. None of these joints are restricted to the axial skeleton or upper extremities, and while the hip and glenohumeral joints are ball and socket joints, the tibiofemoral and humeroulnar are hinge joints.
