Final answer:
The anatomical position is an upright standing position with feet parallel and palms facing forward. Supination is the forearm motion moving the palm from backward to forward, resulting in the palms facing anteriorly, like in the anatomical position.
Step-by-step explanation:
Anatomical Position Description:
The anatomical position is a standardized stance that is used as a reference point in anatomy to ensure consistency when describing the location of anatomical structures.The accurate anatomical role is defined as an upright status role, with the toes at shoulder width and parallel, feet dealing with forward.The top limbs ought to be held out to the side, and the fingers of the palms ought to face forward. This standardized stance helps in reducing confusion when referencing different parts of the body.
When referring to supination forearm motion, this involves moving the palm of the hand from a palm backward position to a palm forward position, which is the supinated position. In this position, the radius and ulna in the forearm are parallel to each other. Conversely, in the pronated position where the palm faces backward, the radius and ulna cross over each other to form an X-shape.
