Document Summary
10-1: skeletal muscle performs six major functions our bodies contain three types of muscle tissue: skeletal muscles the tissue moves the body by pilling on the bones. 10-2: a skeletal muscle contains muscle tissue, connective tissues, Organization of connective tissues each muscle layer has three layers of connective tissue: epimysium is a dense layer of collagen fibers that surround, it separates the muscle from nearby tissues and organs. Blood vessels and nerves the connective tissues of the endomysium and perimysium contain the blood vessels and nerves that supply the muscle fibers muscles have extensive vascular systems that: supply large amounts of oxygen supply nutrients carry away wastes they contract only when the central nervous system stimulates them axons nerve fibers extending from the cell, penetrate the epimysium, branch through the perimysium, and enter the endomysium to innervate individual muscle fibers skeletal muscles are voluntary muscles, controlled by the nerves of the central nervous system.
