acetylcholine neurotransmitter that signals a skeletal
muscle fiber
to contract
synaptic cleft The narrow gap that separates the motor
neuron
from muscle fiber
motor unit a nerve fiber + all of the muscle fibers it
controls =
fast twitch glycolytic muscle fibers that have explosive power
but tire
rapidly; use glycolysis to produce ATP
slow twitch oxidative muscle fibers that maintain steady power
and use
cellular respiration to produce ATP
fast oxidative-glycolytic quick contracting, use mostly glycolysis but
some
cellular respiration to produce ATP, tire
after a
while
