Fascial compartments of arm

Human anatomy

1. Fascial compartments of Arm Dr. Heta Patel(PT) Assistant Professor ARIP

2. Fascial compartments of the Arm The brachial fascia: A sheath of deep fascia encloses the arm like a sleeve It is continuous superiorly with the pectoral and axillary layers of fascia. It is attached inferiorly to the epicondyles of the humerus and the olecranon of the ulna and is continuous with the antebrachial fascia

3. Intermuscular septa: The medial and lateral intermuscular septa extend from the deep surface of the brachial fascia to the medial and lateral supracondylar ridges of the humerus Dividing the arm into Anterior (flexor) fascial compartment Posterior (extensor) fascial compartment Each of which contains muscles serving similar functions, nerves, and blood vessels that supply

4. Triceps brachii Lateral head Humerus Long head Medial head (a) Brachialis Short head Long head (a) Muscles of the arm Extensors Flexors Others Posterior compartment of arm (extends elbow); innervation: radial nerve Biceps brachii Anterior compartment of arm (flexes elbow); innervation: musculocutaneous nerve
