Question

What is the term used to describe the movement of the radial head towards the posterior/anterior direction?

1) Posterior glide
2) Anterior glide
3) Radial glide
4) Lateral glide

Answer 1

Medial rotation moves the anterior surface of a limb towards the midline of the body, while lateral rotation moves it away from the midline.

Step-by-step explanation:

Rotation can also occur at the ball-and-socket joints of the shoulder and hip. Here, the humerus and femur rotate around their long axis, which moves the anterior surface of the arm or thigh either toward or away from the midline of the body. Movement that brings the anterior surface of the limb toward the midline of the body is called medial (internal) rotation. Conversely, rotation of the limb so that the anterior surface moves away from the midline is lateral (external) rotation.
