ch 10-11 Flashcards
cardiac muscles contain high levels of
glycogen (energy stores)
cardiac cell features found
striations, mononucleated, glycogen, intercatated disc
smooth muscle features
mononucleated
tapering cytoplasm
fusaform shape
NO striations
what happens to your muscles as you age
loss of muscle mass, cell component reduced
fat accumulates
glycolytic fibers atrophy
reduced nervous system efficiency
myopathies
disease of the muscles
muscular dystrohy
muscles degenerate and replaced by scar and adipose tissue
sex link hereditary gene
mysatheina gravis
autoimmune disease
destruction of ACh receptors
ptosis
drooping eye lid
trouble swallowing, limb weakness
endomysium
wraps muscle fiber
perimysium
wraps fascicle (bundle)
epimysium
wraps muscle
fascia
wraps muscle group
compartments are enclosed by
fasciae/ intermuscular septa
compartments of muscles consist of
functionally related muscles
nerves and blood vessels
compartments syndrome
pressure inside a compartment due to overuse or contusion
