Chapter 26 - The muscular system. Bones and joints do not themselves produce movement. By alternating between contraction and relaxation, muscles cause bones and supported structures to move. The human body has more than 600 individual muscles. Although each muscle is a distinct structure, muscles act in groups to perform particular movements. This chapter focuses on the differences among three muscle tissue types, the structure of skeletal muscles, muscle actions, and the names of skeletal muscles. | Chapter 26 PowerPoint® to accompany Second Edition Ramutkowski Booth Pugh Thompson Whicker Copyright © The McGraw-Hill Companies, Inc.

The Muscular System Introduction Bones and joints do not themselves produce movement. The human body has more than 600 individual muscles By alternating between contraction and relaxation, muscles cause bones and supported structures to move. You will focus on the differences among three muscle tissue types, the structure of skeletal muscles, muscle actions, and the names of skeletal muscles. Functions of Muscle Muscle has the ability to contract, and this contraction allows muscles to perform various functions. Functions: Movement Stability Control of body openings and passages Heat production Click for Larger View Skeletal Muscle Functions of Muscle Movement: Skeletal muscles are attached to bones which allow you to walk or wave your hand. Smooth muscle is found on organ walls such as the intestine. Contractions produces movement of food through the intestine. Cardiac muscle produces the pumping of the blood in the heart. Functions of Muscle Stability: Muscles hold your bones together to stabilize joints. Small muscles hold your vertebrae together to stabilize your spinal column. Functions of Muscle Controlling
