In human anatomy, the acromion (from Greek: akros, "highest", ōmos, "shoulder", pl.: acromia) is a bony process on the scapula (shoulder blade). Together with the coracoid process, it extends laterally over the shoulder joint. The acromion is a continuation of the scapular spine, and hooks over anteriorly.

The head and neck are emptied of blood by the subclavian vein and jugular vein. Right side of neck dissection showing the brachiocephalic, right common carotid artery and its branches. The brachiocephalic artery or trunk is the first and largest artery that branches to form the right common carotid artery and the right subclavian artery.
A number of small fluid-filled sacs known as synovial bursae are located around the capsule to aid mobility: Between the joint capsule and the deltoid muscle is the subacromial-subdeltoid bursa. Between the capsule and the acromion is the subacromial bursa. The subcoracoid bursa is between the capsule and the coracoid process of the scapula.

The neck is the part of the body in many vertebrates that connects the head to the torso.
