- Anything denoting the muscles relationship to another muscle such as e.g. superior, inferior etc. should always be used as a suffix and not a prefix, to create better sortability of the list. Location The location of the muscle in a standard human body.
The septa are formed from the fascia which is made up of a strong type of connective tissue. The fascia also separates the skeletal muscles from the subcutaneous tissue. [2] Due to the great pressure placed on the leg, from the column of blood from the heart to the feet, the fascia is very thick in order to support the leg muscles. [3]
The calf (pl.: calves; Latin: sura) is the back portion of the lower leg in human anatomy. [1] The muscles within the calf correspond to the posterior compartment of the leg. The two largest muscles within this compartment are known together as the calf muscle and attach to the heel via the Achilles tendon.
The muscle produces simultaneous plantar flexion and supination in the non-weight-bearing leg, and approximates the heel to the calf of the leg. The flexor hallucis longus arises distally on the fibula and on the interosseus membrane from where its relatively thick muscle belly extends far distally.
The anterior compartment of the leg is supplied by the deep fibular nerve (deep peroneal nerve), a branch of the common fibular nerve. The nerve contains axons from the L4, L5, and S1 spinal nerves. Blood for the compartment is supplied by the anterior tibial artery, which runs between the tibialis anterior and extensor digitorum longus muscles.
The plantaris muscle and a portion of its tendon run between the two muscles, which is involved in "locking" the knee from the standing position. Since the anterior compartment of the leg is lateral to the tibia, the bulge of muscle medial to the tibia on the anterior side is actually the posterior compartment. The soleus is superficial to the ...

Only skeletal and smooth muscles are part of the musculoskeletal system and only the muscles can move the body. Cardiac muscles are found in the heart and are used only to circulate blood; like the smooth muscles, these muscles are not under conscious control. Skeletal muscles are attached to bones and arranged in opposing groups around joints. [8]
