non striated
single nucleus
myocytes are long
smooth muscle function
involuntary movement
regulations flow and contractions
smooth muscle location
digestive tract
intestine
uterus
blood vessels
cardiac muscle structure
striated
myocytes are short
intercalated discs
intercalated discs
gap junctions that allow rapid electric transmission and nutrition exchange
cardiac muscle function
involuntary movement of cardiac movement, pumps blood.
skeletal muscle structure
elongated myocytes, lie in parallel held together by connective tissue
many nuclei
skeletal muscle function
voluntary movement
skeletal muscle location
all over body
head and neck- chewing, facial expressions
trunk- moves chest
upper extremity- shoulders, arms
striations function
generate force and contract to support movement (skeletal) and to pump blood (cardiac)
