In this article, we shall look at the anatomy of the muscles of the upper arm â their attachments, innervation and actions. There are three muscles located in the anterior compartment of the upper arm â biceps brachii, coracobrachialis and brachialis. They are all innervated by the musculocutaneous nerve. A good memory aid for this is BBC â biceps, brachialis, coracobrachialis.
HIP ADDUCTOR MUSCLES The adductor muscles are a group of four muscles located in the internal femoral region on both sides of the body. Their names are: 1) Adductor Longus, 2) Adductor Brevis, 3) Adductor Magnus, and 4) Gracilis. These muscles are shown in Figure 1 below Figure 1. The Hip Adductor Muscles. INNERVATION (NERVE SUPPLY) The nerve supply to the all of the adductor muscles is from the Obturator nerve. The Adductor Magnus receives additional nerve supply from the Great Sciatic Nerve.
