Axillary region: Armpit
Cervical region: Neck
Scapular region: Scapula
Brachial region: Arm. In the axillary region, we find the axilla's suspensory ligament, lymph collectors, and nodes along with adipose tissue. This area serves as the functional unit for shoulder movement. The cervical region refers to the neck's spine, comprising seven vertebrae separated by discs. The scapular region is the scapula, a large, flat bone in the upper back, linked with the clavicle to form the shoulder girdle. The brachial region pertains to the arm, named for the brachial muscle located in the ulna, which exerts tension on the elbow joint.
