motor (action)
the nervous system works in tandem with what system
endocrine (hormones)

what makes up the central nervous system
brain and spinal cord
two things contained in the peripheral nervous system
cranial nerves
spinal nerves
carries info from periphery to CNS

two subsystems of the PNS
somatic nervous system
autonomic nervous system
what nervous system is the voluntary movement of muscles
somatic nervous system
what nervous system is the involuntary system
autonomic nervous system
which PNS uses ganglions
autonomic nervous system
a collection of neuronal bodies found in the voluntary and autonomic branches of the peripheral nervous system
ganglion
fundamental unit of the nervous system, nerve cell
neuron
what travels along nerve cells (neurons)
electrical impulses
what makes electrical impulses travel faster
myelin sheath
In order for transmission to occur from one cell to the next, this electrical message must be translated into a what
chemical message
the space between the nerve cells
synapse
part of the neuron that is away from the nerve into the synapse (proximal)
axon
part of the neuron that is toward the nerve from the synapse
dendrite
neurotransmitters cross the synapse and trigger what
receptors
two divisions of the autonomic nervous system
sympathetic
parasympathetic
the sympathetic nervous system is known as
adrenergic system
the parasympathetic nervous system is known as
cholinergic system
which ANS is the energy expending system
