At a hinge joint what movements are possible? 1) lateral rotation and flexion
2) flexion and extension
3) adduction and abduction
4) medial and lateral rotation

At a hinge joint the movements possible are flexion and extension.

Explanation:

Hinge joints, such as elbow and knee, are a type of joint with high mobility but a limited range of motion on several planes, since they can only perform flexion and extension.  

In this type of joint, cartilage, bone and muscle components contribute to the stability, resistance and strength of the joint, allowing movement in only one plane.

    Other movements such as lateral rotation and flexion , adduction and abduction or medial and lateral rotation are performed by other types of joints, such as ball-and-socket joints, with movements in various planes.
