What describes the position when the palm faces upward?

Supination refers to the position of the body when the palm is facing upward or forward. This anatomical position is commonly used to describe movements in the forearm and wrist. When the forearm is in a supinated position, the radius and ulna (the two long bones in the forearm) are parallel to each other, allowing the palm to face up.

In contrast, pronation is the movement that turns the palm downward. The neutral position describes the midpoint between supination and pronation, where the palms may face the body or are held at the sides. Flexion, on the other hand, refers to a bending movement that decreases the angle between body parts, such as bending the elbow or knee.

Understanding these terms is essential in veterinary medicine, as they help describe the position and movement of animals during examinations, procedures, or surgeries.
