1 The Muscular System Chapter 15-3 Page 488 Chapter 15-3 Page 488

2 Muscle Facts  Muscles are tissues that can shorten along their length  Muscles only move things when they contract or shorten  There are more than 600 muscles in the muscular system  Muscles are tissues that can shorten along their length  Muscles only move things when they contract or shorten  There are more than 600 muscles in the muscular system

3 Muscular System  The Muscular System works with the Skeletal System to provide movement.  The Muscular System works within internal organs to support bodily functions  The Muscular System works with the Skeletal System to provide movement.  The Muscular System works within internal organs to support bodily functions

5 2 Muscle Categories Voluntary Muscles Involuntary Muscles Skeletal Cardiac Smooth

6 Voluntary Muscles  Muscles that are under conscious control Examples:  Muscles that move joints (biceps and triceps)  Muscles that move skin (smiling, raising your eyebrows)  Muscles that are under conscious control Examples:  Muscles that move joints (biceps and triceps)  Muscles that move skin (smiling, raising your eyebrows)

7 Voluntary Muscles

8 Voluntary Muscle -

9 Involuntary Muscles  Muscles NOT under conscious control  Examples: heart, digestive organs, diaphragm (breathing)  Muscles NOT under conscious control  Examples: heart, digestive organs, diaphragm (breathing)
