skeletal, smooth, cardiac
|
|
|
___= muscles attached to the bones of the skeleton, that are control muscles, and voluntary/striated
|
skeletal
|
|
|
___= location and function of the skeletal muscles
|
throughout the skeleton
-mvt of limbs, trunk, neck |
|
|
___= control muscles that are unstriated, involuntary
|
smooth muscle
|
|
|
___= location and function of the smooth muscles
|
lining of the digestive tract, urogenital system, airways, blood vessels
function=contraction |
|
|
___= control muscles that are involuntary and striated
__= location ___= function |
cardiac
heartcontracts intrinsically assisting in circulation of blood |
|
|
Function of the muscular system..contraction/relaxation
___= examples of smooth functions ____= examples of skeletal functions |
smooth= mix and propel food in GIT, control distribution of blood in vessels, Ex: pupil in eye
skeletal- locomotion, respiration (moves thoracic cavity) |
|
|
___= arranged in bundles surrounded by connective tissue
- parts= endomysium, perimysium, epimysium |
skeletal muscle organization
|
|
|
____= connective tissue btw individual muscle fibers, surrounds each cell
____= sheath surrounding bundles of muscle fibers ____= connective tissue around an entire muscle, becomes the muscle sheath |
endomysium
perimysium epimysium |
|
|
___= muscle arrangement when muscle is shortening, but weak
____= spindle-like arrangement ____= feather-like arrangement- increases the power of a muscle |
parallel
fusiform pennate ( unipennate, multipennate, bipennate) |
|

___= example of a parallel muscle
___= ex of fusiform muscle ___= ex of unipennate muscle ___= ex of bipennate muscle ___= ex of multipennate muscle |
parallel- abdominals
fusiform- biceps unipennate- long digit extensor bipennate- femur multipennate- deltoid |
|
|
___= cords or bands, flat fibrous sheets associated w flat muscles , loin, linea alba

|
|
___= less mobile attachment
___= more movable attachment |
origin
insertion |
|
|

Flexor-stifle
Extensor- hock adductor- deep pectoral abductor- deltoid sphincter-(encircle an opening) pyloric sphinctor cutaneous-superficial fascia, mvt of skin(horses) |
|
|
___= muscle directly responsible for producing an action (flexion)
____= muscle that opposes an action( extension) ____= muscle that opposes and undesired action of agonist (synergistic and agonistic work together) |
agonist
antagonist synergism |
|
