Autonomic nervous system
Nerves that carry involuntary impulses to
smooth muscle, cardiac muscle, and various
glands
Axon
Carry impulses away from the
cell body of a neuron.
Brain
Largest and most complex
nerve tissue in the body
Brain stem
Monitors and control automatic
functions of the body.
Cerebellum
Below the cerebrum it
coordinates body movements
Cerebrum
The twisting mass of gray
matter of the brain.
Dendrite
Receives impulses passed
along from other neurons
Impulses
Electric signals that travel
along neurons
Interneurons
Transmit signals between
neurons
Lobes
Sections of the cerebrum that
control different kinds of thoughts.
Motor neurons
Transmit information from the central
nervous system to the muscles making them
move.
Myelin sheath
Fatty coating that surrounds axons
and increases the speed of impulses.
Nerve
A bundle of nerve fibers
Nervous System
Control center for the entire
body
Neuron
Nerves cells that make up the
nervous sytem
Neurotransmitter
Chemicals that are released in a synapse to
transmit an impulse to a neighboring
neuron
Reflex
An automatic response that occurs
rapidly and without conscious control.
Sensory neurons
Transmit information from the outside
world to the spinal cord or brain.
Soma
Cell body of a neuron
Somatic nervous system
Controls voluntary movements
of skeletal muscles
Spinal Cord
Nerves that run up and down the length of
the back and transmit most messages
between the body and brain
Synapse
Fluid filled gap between a neuron and
another cells where impulses are
transmitted.
