The cell body receives a nerve impulse from dendrites
Dendrites
Cell body
Nerve impulse
Impulse
Axon terminal
axon highway
dendrites
The impulse travels along the axon to the axon terminal
Neuromuscular Junction
Now at the neuromuscular junction (synaptic cleft) (here the nervous and muscular systems meet
Nervous
Muscular
Ach, a common neurotransmitter, is released and binds to membrane of the muscle, the protective later

Some new ach for my roof!

Come on in Ca2+, feel free to bring your friends in too there's plenty of room
The cell membrane changes (depolarization) to allow Ca2+ ions to enter into the muscle fiber

actin: Excuse me just sliding by
Mysosin: Don't mind me just coming by
When the level of Ca2+ ions is raised, actin and mysosin slide past each other, and the skeletal muscle fibers contract

Ach Neurotransmitter
When the level of Ca2+ ions decreases, or heads back outside the fiber, the skeleton muscle fibers relax
