Presentation Transcript

Fxn of skeletal muscle
Fxn of Skeletal Muscle:

Movement

Heat Production

Posture


Movement
Movement

  • attached to bone contracts thus producing movement

  • Ex: walking, talking, chewing, blinking


Heat production
Heat Production

  • Reactions during muscle contraction produce heat

  • Heat contributes to constant body temperature (homeostasis of temperature)


Why do we shiver when we re cold
Why do we shiver when we're cold?

  • Shivering is a result of muscle contraction. This produces heat thus increasing your body temperature.


Posture
Posture

  • Continuous partial contraction of skeletal muscles

  • Allows standing, sitting, and maintaining a stable body position while walking, running, and all other movements.



Pumping blood
Pumping Blood

  • Cardiac muscle cells contract to provide all cells with blood

  • Blood has all of the nutrients that cells need to be healthy


Fxn of smooth muscle
Fxn of Smooth Muscle:

transport nutrients & waste


Transport nutrients waste
Transport Nutrients/Waste

  • Smooth muscles line the inside of hollow organs and blood vessels

  • Ex: swallowing, digesting food in intestines, defecating, erection
