PRESENTATION OUTLINE
THE MUSCULAR SYSTEM ...
- permits movement of the body
- Maintains posture
- Circulates blood throughout the body
- Consists of skeletal, smooth, and cardiac muscles.
- Forms the musculoskeletal system along with the skeletal system
How we know the muscular system is working properly:
-Muscles maintain posture
-Movement(muscles contract)
-Blood is pumping through veins because of cardiac muscles
-Limbs are able to bend because of tendons and ligaments
How we know the muscular system is not working properly:
-Loss of function at the junction can produce paralysis
-muscles are spasming
-unable to stand/sit up straight
- limping after you have pulled a muscle
