Unit 4 Chapters 9 & 10: The Muscular System, Muscle Tissue and Physiology

This unit will cover the muscular system.

What are the muscle cells called?

Myocytes

What is the main function of muscle tissue?

Contraction

What are the 3 types of muscle tissue?

• Cardiac muscle

• Smooth muscle

• Skeletal muscle

Structure of Skeletal muscle

• Skeletal muscle contains blood vessels that supply muscle cells with oxygen and glucose, and remove wastes, and nerves that coordinate muscle contraction

• Skeletal muscle also contains connective tissue

• Each individual muscle cell (fiber) is surrounded by the endomysium

• Several muscle cells are bundled together into a fascicle by the perimysium

• All fascicles that make up a muscle are, in turn, enclosed
