Muscle: helps body move either by contracting or relaxing the muscle.
skeletal
passes along stimulation so that intercalated discs all contract together
cardiac
Passes along stimulation in a wave-like pattern that comes from the short form of the fibers.
smooth
Produces the pulse you feel when you touch your wrist
cardiac
Moves food through the intestines
smooth
keeps the body upright
skeletal

axon
A rapid change in a cell’s electrical charge that reverses the plasma membrane’s electrical polarity.
action potential
A part of the central nervous system; extends from the brain stem through the vertebrae
spinal cord
The junction between nerve endings and muscle fibers
neuromuscular junction
A chemical in the neuromuscular junction that aids in stimulating or inhibiting muscle contraction.
