ATP hydrolysis/formation of cross-bridges/power stroke/detachment of myosin from actin
4 steps of the contraction cycle
formation of cross-bridges
step of the contraction cycle where the myosin head attaches to the myosin-binding site on actin
neuromuscular junction/synapse/synaptic cleft/neurotransmitter/synaptic vesicles/motor end plate
structures involved in the contraction process
action potentials arise at the interface of the motor neuron and muscle fiber
sacs suspended within the synaptic end bulb containing molecules of the neurotransmitter acetylcholine
release of ACh/activation of ACh receptors/production of muscle action potential/termination of ACh activity
nerve impulses elicit a muscle action potential in the following way
