Description
The muscles of the arm are a group of muscles of the upper limb that act on the humerus, radius, and ulna. They are involved in movements of the arm and forearm and help to stabilize the upper limb during fine motor movements.
For classification purposes, the muscles of the arm are divided into two distinct compartments by the humerus and the medal and lateral intermuscular septa:
- muscles of the anterior compartment of arm;
- muscles of the posterior compartment of arm.
