Fascial compartments of arm
- Fascial compartments of arm
On the human body, the limbs can be divided into segments, such as the arm and the forearm of the upper limb, and the thigh and the leg of the lower limb. If these segments are cut transversely, it is apparent that they are divided into multiple sections. These are called fascial compartments, and are formed by tough connective tissue septa. The (upper) arm is divided into two compartments by the lateral intermuscular septum and the medial intermuscular septum: anterior and posterior.
Anterior compartment
It contains the Biceps brachii muscle, Brachialis muscle, and Coracobrachialis muscle.
It is supplied by the musculocutaneous nerve [NormanAnatomy|lesson4nervesofant&postarm] and brachial artery.
Posterior compartment
It contains the Triceps brachii muscle.
It is supplied by the radial nerve and profunda brachii.
