Muscular System 4

Muscular System IV: In this lecture, Professor Diamond continues her description of the muscular system, describing the gluteal muscles and muscles of the thigh and leg. She also discusses muscle histology. She begins with the gluteal muscles, including the gluteus maximus, gluteus medius, and gluteus minimus. She continues by describing muscles of the thigh, including the quadriceps femoris and the hamstring muscles. She describes the anatomy of the femoral triangle, the major nerve, artery, vein, and lymphatics that it contains. She then moves on to the anterior and posterior muscles of the leg. She concludes by discussing the histology of muscles, starting with smooth or visceral muscles and cardiac muscle. She discusses smooth muscles cells in depth, including their role in blood vessels and the iris, and then describes the tubular cells of cardiac muscle.
