Question

What is the term for the rotation of the forearm so the palm is upward or facing anteriorly?

a) Supination
b) Pronation
c) Flexion
d) Abduction

Answer 1

Supination is the term for the rotation of the forearm so the palm is upward or facing anteriorly, while pronation is the opposite motion where the palm faces backward.

Step-by-step explanation:

In biology, the term for the rotation of the forearm so the palm is upward or facing anteriorly is supination. In this position, the radius and ulna are parallel to each other.

The opposite motion, where the palm faces backward, is called pronation. The proximal radioulnar joint allows for rotation of the radius, causing the distal end to cross over the distal ulna when pronating.

Answer 2

The term for the rotation of the forearm so the palm is facing upward or anteriorly is: a) Supination

Supination: This is the movement of the forearm and hand in such a way that the palm faces upward or anteriorly. In the anatomical position (the standard reference position for the body), the forearm is in supination.

Pronation: In contrast, pronation is the movement of the forearm and hand that results in the palm facing downward or posteriorly. It is essentially the opposite of supination.

Flexion: This term refers to the bending of a joint, usually bringing two parts closer together. For example, bending the elbow is a form of flexion.

Abduction: This term is used to describe the movement of a body part away from the midline of the body. For instance, lifting your arm sideways away from your body is a form of abduction.
