Brachial fascia

From WikiMD's Wellness Encyclopedia

(Redirected from Fascia brachii)

Brachial Fascia is a layer of deep fascia that encloses the muscles of the arm, also known as the brachium. It is a continuation of the pectoral fascia and the axillary fascia.

Etymology[edit | edit source]

The term "Brachial" is derived from the Greek word "brachion" which means arm. "Fascia" is a Latin term that refers to a band or a bundle.

Anatomy[edit | edit source]

The brachial fascia is a deep fascia that envelops the muscles of the arm. It is continuous with the pectoral fascia at the front and the axillary fascia at the armpit. It forms a tubular sheath for the muscles, which allows them to move smoothly against each other. The brachial fascia is thin over the biceps brachii muscle and thick over the triceps brachii muscle.

Function[edit | edit source]

The primary function of the brachial fascia is to reduce friction between the muscles of the arm during movement. It also serves as a conduit for nerves and blood vessels to reach the muscles.

Clinical Significance[edit | edit source]

In certain medical conditions, the brachial fascia can become tight or restricted, leading to pain and limited movement. This is often seen in conditions such as frozen shoulder or adhesive capsulitis. Treatment typically involves physical therapy to stretch and loosen the fascia.
