Document Summary
Comprises largest group of tissues in body. Smooth: appears through body systems as components of hollow organs and tubs. Muscle attachment to bone at the stationary end. Muscle that provides most of the force for a given movement. Muscle consists of a number of muscle bres lying parallel to one another and held together by connective tissue. Muscle is composed of muscle tissue and connective tissue. Three types of connective tissue: extensions of deep fascia: epimysium. Layer of connective tissue around entire muscle (deep to super cial muscle) Connective tissue covering that surrounds a bundle of muscle bres (muscle cells) Actin and myosin are often called contractile proteins. Actin and myosin are not unique to muscle cells, but are more abundant and more highly organized in muscle cells. Protein molecule consisting of two identical subunits spaced somewhat like a golf club (tails are intertwined around each other, globular heads project out at one end)
