WebMuscles attach to bones directly or through tendons or aponeuroses. Skeletal muscles maintain posture, stabilize bones and joints, control internal movement, and generate heat. Skeletal muscle fibers are long, multinucleated cells. The membrane of the cell is the sarcolemma; the cytoplasm of the cell is the sarcoplasm. WebA nerve is the primary structure of the peripheral nervous system (PNS) that encloses the axons of peripheral neurons. A nerve provides a structured pathway that supports neuron function. A nerve consists of many structures including axons, glycocalyx, endoneurial fluid, endoneurium, perineurium, and epineurium.
WebScore: 5/5 (17 votes) (Epi - greek for upon, mys - greek for muscle). The muscle fibres are divided up into bundles of fibres called 'fascicles'. Fibrous sheaths that surround the fascicles are called the perimysium (peri is greek for around). Blood vessels, the lymphatics and the nerves are all found in the perimysium.
