Postural/Skeletal movement, maintain posture, protect and support other soft tissue, control openings into the body, maintain body temperature, store nutrients
These are the 6 functions of skeletal muscle.
Postural/Skeletal Movement
this function of the skeletal muscle controls contracting pulls on tendons, which inturn moves the bone.
Maintain Posture
this function of skeletal muscle provides constant tension in resting muscles. This maintains the body position, whether we are sitting or standing.
Protect and Support other Soft Tissue
this function of skeletal muscle supports the weight of the visceral organs and shields them from injury.
Controls openings into the Body
this function of the skeletal muscle provides circular muscle sphincters. This controls the openings to the urinary and digestive system.
Maintain body temperature
This function of the skeletal muscle states that contracting muscles require a lot of energy. Thus, they produce a large amount of heat
Store Nutrients
this function of skeletal muscle stores a large amount of amino acids
Organization of Skeletal Muscle
3 layers of Connective Tissue that support each muscle and compression of the deep fascia
Endomysium
this is the innermost layer.
Endomysium
layer that contains elastic connective tissue that surrounds each muscle fiber, a muscle fiber, capillaries, neurons, and satellite cells.
perimysium
this is the middle layer
perimysium
this layer surrounds many muscle fibers and bundles then into fascicles bundle of muscle fibers
epimysium
the outer most layer
epimsium
layer that bundles together all fasciles
it functions in separating muscles from other muscles and organs
