Question

Technically, the arm is the portion of the upper limb of the body between the shoulder and the elbow. The bone of the upper arm is the humerus. Bones of the forearm are the ulna and the radius. The upper extremity is composed of the arm, forearm, and hand. Practice using the word parts you have learned for the bones of the arm and hand. Humero+scapular refers to the _____ and the scapula.

Answer 1

The term "humero+scapular" refers to the region involving both the humerus, the bone of the upper arm, and the scapula, the shoulder blade, specifically indicating the shoulder region where these two bones articulate.

Step-by-step explanation:

When combining the word parts for bones and referring to humero+scapular, we are discussing the relationship or area involving both the humerus, which is the bone of the upper arm, and the scapula, the shoulder blade. Specifically, the term indicates a part of the body where these two parts come together or interact, which is the shoulder region.

The humerus is the single bone in the upper arm that articulates at the shoulder with the scapula, forming the shoulder joint, and at the elbow with the forearm, specifically the ulna and radius. This anatomy allows for a wide range of motion in the upper limb, which includes the arm, the forearm (made up of the ulna medially and the radius laterally), and the hand (composed of the carpal bones, metacarpal bones, and phalanges).
