Document Summary

Chapter 10. m (muscle) mm (muscles: the skeletal mm are organs (true or false, each cell in the skeletal m tissue is a single m fiber. (true or false). The skeletal m cell is also known as --------------------------: the cell membrane of the skeletal m cell is known as ----------------. The cytoplasm of the skeletal m cell is also known as --------------- Explain all the functions of the skeletal mm. 4: name the 4 primary tissue types. Name the three types of m tissue: give the location of the cardiac m tissue. Endomysium contains blood vessels (capillaries) (t or f). At each end of the muscle, the collagen fibers of epimysium, perimysium and endomysium come together to form a ------------------. The diaphragm usually works outside our conscious awareness. What is a satellite cell: even though the skeletal m cell is very large, all regions of the cell must contract simultaneously. Transverse tubules encircle the sarcomere (t or f).
