Pectoral fascia

From WikiMD's Wellness Encyclopedia

Pectoral Fascia is a thin layer of tissue that envelops the Pectoralis major and Pectoralis minor muscles in the chest. It is part of the fascial system, which is a network of connective tissue that surrounds and supports the muscles, organs, and other structures in the body.

Etymology[edit | edit source]

The term "Pectoral Fascia" is derived from the Latin words "pectus" which means chest, and "fascia" which means band. Thus, "Pectoral Fascia" can be translated as "chest band".

Structure[edit | edit source]

The Pectoral Fascia is a thin, flat sheet of connective tissue that is tightly bound to the underlying Pectoralis major muscle. It extends laterally to the axillary fascia, and medially to the sternum. It also extends superiorly to the clavicle, and inferiorly to the rectus sheath of the abdominal muscles.

Function[edit | edit source]

The primary function of the Pectoral Fascia is to provide a smooth, slippery surface that allows the Pectoralis major and Pectoralis minor muscles to move freely against the surrounding tissues. It also helps to hold these muscles in place, and provides a pathway for nerves and blood vessels.

Clinical significance[edit | edit source]

Abnormalities or injuries to the Pectoral Fascia can lead to a variety of medical conditions, including fasciitis, myofascial pain syndrome, and fibromyalgia. Treatment for these conditions may involve physical therapy, medication, or in some cases, surgery.
