Question

What is the term for the rotation of the forearm so the palm is downward or facing posteriorly?

a) Pronation
b) Supination
c) Adduction
d) Extension

Answer 1

Supination and pronation are movements of the forearm. Supination refers to the position where the palm of the hand is facing forward, while pronation refers to the position where the palm is facing backward.

Step-by-step explanation:

Supination and pronation are movements of the forearm. In the anatomical position, the upper limb is held next to the body with the palm facing forward. This is the supinated position of the forearm. In this position, the radius and ulna are parallel to each other. When the palm of the hand faces backward, the forearm is in the pronated position.
