Document Summary
The axilla is the triangular space located between the chest and the shoulder joint. It contains the biceps, coracobrachialis, the brachial plexus and the axillary artery and vein, plus the axillary lymph nodes. The surroundings are a connective sheath known as the axillary sheath. Superior border: - apex, rib 1, clavicle, scapula. This is a space that has the axillary nerve passing through it and the radial nerve can also be viewed from this space. It is classified as a long bone and appendicular and is located on the lateral side of the arm in the anatomical position. It has major function in force transfer, and the curvature of this bone has been said to aid in distal forearm force transfer. The radius is the provider of attachment for all muscles that are involved in pronation and supination. The proximal end of the radius is structured for a pivot joint.
