THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Proximal means ‘closer to the origin of a structure’, like a limb, while distal means ‘farther away from the structure’s origin’. Thus, when comparing the shoulder to the elbow, the shoulder is proximal and the elbow is distal.

Detailed explanation-2: -The elbow joint is connected to the wrist with the bones radius and ulna. Humerus connects the shoulder with the elbow joint. As the length of the humerus is more than the length of the radius and ulna, the elbow joint is proximal to the wrist and distal to the shoulder.

Detailed explanation-3: -The upper arm bone or humerus connects from the shoulder to the elbow forming the top of the hinge joint. The lower arm or forearm consists of two bones, the radius and the ulna.
