Slide1
The Muscular System
Goal: To describe the structure and function of the muscular system.
Slide2made up of over 600 different muscles
consists of two different
types of tissue: connective tissuemuscle tissue
What is the Muscular System?
Slide3Slide4What are the Functions of the Muscular System?
To create movement by working with bones, ligaments, and tendons.
To move food through the digestive system.
To move blood through the body by pumping the heart.
To produce heat.To provide protection to inner organs.
Slide5What are the 2 Different Types of Muscle?
Voluntary
:
Muscle action that is under your control.Most skeletal movement is voluntary.Examples:Walking, talking, running, writing, jumping, stretching
Involuntary
Muscle action that is NOT under your control.
Cardiac and smooth muscle are involuntary.
Examples:
Heart beating, food moving through the digestive tract, reflexes (skeletal)
Skeletal muscle can be both voluntary and involuntary (reflexes).
Slide6What are the Types of Muscle?
Skeletal Muscle:
Attached to the bones for movement. Helps protect your inner organs
.
Cardiac Muscle:
Special type of muscle found only in your heart. This type of muscle causes your heart to beat
.
Smooth Muscle:
Lines your digestive tract and blood vessels.
Smooth
muscle moves
food and blood through your body
.
Slide7Slide8What are Tendons?
Tendons attach muscles to bones.
Tendons are made up of strands of flexible connective tissue.
When a muscle contracts (gets shorter) the tendon pulls on the bone.
Slide9How do Muscles Work in Pairs?
Muscles work in pairs to cause smooth, controlled movements.
Many of our basic movements are the result of pairs of muscles bending and straightening.
Flexor
- a muscle that contracts
to
bend
a part of the body.
Extensor
– a muscle that
contracts
to
straighten
a part of the body.
Slide10Flexors and extensor always work opposite of one another.
