how many nuclei in smooth muscle
skeletal
which muscle tissue is voluntary
branches; striations
description of cardiac muscle
long cylindrical; striations
description of skeletal muscle
spindle/ pinched at the ends
description of smooth muscle
heart
where is cardiac muscle found
muscles/ bone and skin
where is skeletal muscle found
hollow organs
where is smooth muscle found
movement, balance, stabilizing joints, and heat generation
4 skeletal muscle functions
tendons
what attaches muscle to bone
... fascicle
a group of muscle fibers is a ...
... muscle
a group of fascicles are ...
epimysium
encloses the entire skeletal muscle
perimysium
encloses a fascicle
endomysium
encloses a single muscle fiber
sarcolemma
plasma membrane for a muscle cell
myofibril
long organelle that fills a muscle cell
twitch
brief, single muscle contraction
summing
addition of contractions
incomplete tetanus
not smooth, very short rests between contraction
complete tetanus
smooth, no rest between contractions
32 ATP
how much energy is stored in muscles
isotonic contraction
what type of muscle contraction: muscles shorten, movement occurs
isometric contraction
what type of muscle contraction: muscles can't shorten, no movement occurs
builds endurance, resistance to fatigue
how does aerobic exercise affect the muscles
changes size and strength
what does isometric exercise do to the muscles
rigor mortis
"hard death"
curare
arrowhead poison; used for intubation; causes respitory and cardiac arrest
myalgia: acute muscle pain
what disorder and type is immediate pain and longer contractions due to deficient blood supply
myalgia: delayed muscle pain
what disorder and type is after 24-48 hours from which you havn't done an activity in a while and tear muscle cells and fibers causing tissue swelling
duchenne muscular dystrophy
sex-linked recessive disorder diagnosed at a young age
