MUSCULAR SYSTEM Skeletal muscles allow our bodies to bend, walk, sit, chew and talk. Humans have more than 600 muscles in their bodies. Muscles are named in various ways: by the action they perform (extensor, flexor): by their size (maximus, minimus), or length (brevis, longus); by their shape (delt...
