Human Shoulder Anatomy and Physiology Information

Lets learn about human shoulder anatomy and its functions, or shoulder physiology if you will. Below is a short list of facts about the anatomy of the shoulder.

The human shoulder is defined as the group of structures around the shoulder joint (its scientific name is the glenohumeral joint). The shoulder joint is the part where the shoulder blade(known as scapula) and the bone in the upper arm(known as humerus) connect.
There are three bones in each of our shoulders, that is the scapula, humerus and also the collarbone(scientifically called clavicle).
Lets talk about shoulder muscle anatomy. The shoulder uses 30 muscles, and the largest muscle is the deltoid muscle. The most important muscles responsible for controlling the shoulder are the following; the deltoid, the trapezius, the subclavius, the serratus anterior, the levator scapulae, the pectoralis minor, the sternocleidomastoid, the rhomboid minor and the rhomboid major muscle.
The rotator cuff is a group of muscles that is designed to help control arm rotation and stabilization of the human shoulder. The muscles that make the rotator cuff are the teres minor muscle, the supraspinatus muscle, the subscapularis muscle and the infraspinatus muscle.
Perhaps the most interesting part of human shoulder anatomy is the shoulders mobility and wide range of motion. No other joint is as movable as the shoulder joint. The minus side of this is that it is more easily injured than any other joint in the human body.
