Central nervous system
The complex of nerve tissues that controls the activities of the body. Brain and spinal cord.
Peripheral Nervous System
this is the nervous system that includes everything outside of the brain and spinal cord.
Somatic Nervous System
is the part of the peripheral nervous system associated with skeletal muscle voluntary control of body movements.
Autonomic Nervous System

is one of three divisions of the autonomic nervous system. Sometimes called the rest and digest system
convert external stimuli from the environment into internal electrical pulses within the nervous system
a neuron that transmits impulses between other neurons, especially as part of a reflex arc.
neuron whose cell body is located in the spinal cord and whose axon exists outside the spinal cord to control his mainly muscles and glands
is a synapse between a motor neuron and skeletal muscle. This lesson describes the events of synaptic transmission leading to contraction of skeletal muscle.
a drug or chemical that functions in the brain and body as a chemical released by nerve cells to send signals to other cells
Norepinephrine and Epinephrine
hormone that is released by the adrenal medulla and by the sympathetic nerves and functions as a neurotransmitter.
a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.
white matter is bundles of axons that connect multiple pieces of gray matter
the darker tissue of the brain and spinal cord, consisting mainly of nerve cell bodies and branching dendrites.
the outermost layer of the cerebrum that plays an important role in consciousness
a complex system of nerves and networks in the brain, involving several areas near the edge of the cortex concerned with instinct and mood.
