In human anatomy, the infraspinatus muscle is a thick triangular muscle, which occupies the chief part of the infraspinatous fossa. [1] As one of the four muscles of the rotator cuff , the main function of the infraspinatus is to externally rotate the humerus and stabilize the shoulder joint.

The supraspinatus forms part of the rotator cuff and is one of its most frequently damaged components, whether from acute injury or gradual degeneration. [7] Bad posture and age are leading risk factors, with a high prevalence of asymptomatic partial and full tears, as well as symptomatic syndromes with chronic pain.
Shoulder impingement syndrome is a syndrome involving tendonitis (inflammation of tendons) of the rotator cuff muscles as they pass through the subacromial space, the passage beneath the acromion.
The great scapular notch (or spinoglenoid notch) is a notch which serves to connect the supraspinous fossa and infraspinous fossa.It lies immediately medial to the attachment of the acromion to the lateral angle of the scapular spine.
The fossa can be exposed by the removal of skin and the superficial fascia of the back and the trapezius muscle.. The supraspinous fossa is bounded by the spine of scapula on the inferior side, acromion process on the lateral side and the superior angle of scapula on the superior side.
The erector spinae (/ ɪ ˈ r ɛ k t ər ˈ s p aɪ n i / irr-EK-tər SPY-nee) [1] or spinal erectors is a set of muscles that straighten and rotate the back.The spinal erectors work together with the glutes (gluteus maximus, gluteus medius and gluteus minimus) to maintain stable posture standing or sitting.
The gross anatomy of a muscle is the most important indicator of its role in the body. One particularly important aspect of gross anatomy of muscles is pennation or lack thereof. In most muscles, all the fibers are oriented in the same direction, running in a line from the origin to the insertion.
