Infraspinous Fascia[edit]

Diagram of the infraspinous fascia and surrounding structures.

The infraspinous fascia is a dense layer of connective tissue that covers the infraspinatus muscle, which is located in the shoulder region. This fascia is part of the deep fascia of the back and plays a crucial role in the movement and stabilization of the shoulder joint.

Anatomy[edit]

The infraspinous fascia is situated in the posterior aspect of the scapula, specifically covering the infraspinatus muscle, which occupies the infraspinous fossa. The fascia is continuous with the supraspinous fascia above and the deltoid fascia laterally. It is also connected to the spine of the scapula and the vertebral border of the scapula.

Function[edit]

The primary function of the infraspinous fascia is to provide a protective covering for the infraspinatus muscle. It also serves as a site of attachment for muscle fibers and helps to transmit the force generated by the muscle to the humerus. Additionally, the fascia contributes to the compartmentalization of the shoulder region, helping to maintain the structural integrity of the area.

Clinical Significance[edit]

Injury or inflammation of the infraspinous fascia can lead to pain and dysfunction in the shoulder. Conditions such as fasciitis or myofascial pain syndrome may involve the infraspinous fascia, leading to symptoms that can affect shoulder mobility and function. Treatment may involve physical therapy, massage, or other interventions aimed at relieving tension and restoring normal function.

-'''Infraspinous fascia''' is a fibrous membrane that covers the [[Infraspinatus muscle|Infraspinatus]] and [[Teres major muscle|Teres major]] muscles in the human body. It is part of the [[Deep fascia|deep fascia]], a layer of connective tissue which envelops the muscles and other organs of the body.

-The Infraspinous fascia is located in the [[Scapula|scapular]] region, specifically covering the Infraspinatus and Teres major muscles. It is a thin, fibrous sheet that is continuous with the [[Supraspinatus fascia|Supraspinatus fascia]] above and the [[Subscapular fascia|Subscapular fascia]] below.

-In addition, the Infraspinous fascia, like other fasciae in the body, is involved in proprioception, the body's ability to sense its own position, motion, and equilibrium. This is due to the presence of [[Mechanoreceptor|mechanoreceptors]] within the fascia that respond to mechanical pressure and stretch.
