Summary: Page: 2 The body is composed of four primary tissue types: • Epithelial tissue • Connective tissue • Nerve tissue • Muscle tissue Each has its own unique features that distinguish it from the other tissues. Muscle tissue is distinguished and characterized by: • Contractility • Elasticity • Excitability • Extensibility Muscle tissue is subdivided into three categories, based on its cellular structure and biochemistry. They are: • Skeletal muscle tissue • Cardiac muscle tissue • Smooth muscle tissue When we speak of the muscular system, we are usually speaking about the collection of skeletal muscles in the body and the specialized connective tissue elements, tendons, which connect muscles to bones. There are around 700 muscles in the human body. The collective functions of the muscular system can be summarized as follows: • Movement • Support • Form sphincters at body entrances and exits • Posture • Temperature homeostasis. Like the skeletal system, the muscular system also sub
