shoulder

#10
Front (Question)

what is epimysium

Back (Answer)

surrounds entire muscle

#11
Front (Question)

what is perimysium

Back (Answer)

surrounds fascicle (fasciclus)

#12
Front (Question)

what is endomysium

Back (Answer)

surrounds individual muscle fibers/cells

#13
Front (Question)

what is a motor unit

Back (Answer)

motor neuron+ muscle fibers it innervates

#14
Front (Question)

what is a sarcolemma

Back (Answer)

cell membrane

#15
Front (Question)

what is a sarcoplasm

Back (Answer)

cytoplasm

#16
Front (Question)

what is the function of a sarcoplasmic reticulum

Back (Answer)

Ca storage

#17
Front (Question)

___ are thick filaments

Back (Answer)

myosin

#18
Front (Question)

___ are thin filaments

Back (Answer)

actin

#19
Front (Question)

function of Z lines

Back (Answer)

move closer together during contraction

#20
Front (Question)

function of I bands and the H zone

Back (Answer)

shortens during contraction

#21
Front (Question)

when does the muscle have the most cross bridges

Back (Answer)

at rest

#22
Front (Question)

5 stages of the sliding-filament theory

Back (Answer)

• resting • situation-contraction coupling • contraction • recharge • relaxation

#23
Front (Question)

what happens during the resting phase

Back (Answer)

lower Ca-> decrease interaction between actin and myosin

#24
Front (Question)

what happens during the excitation-contraction phase

Back (Answer)

action potential-> Ca release from SR; Ca binds to troponin; tropomyosin shifts position and reveals binding sites
