Nerve Impulse: A message carried
through the body by neurons.
Stimulus (Stimuli): An event or
environmental condition that
triggers a nerve impulse, causing
an organism to respond. (from
the 5 senses)
___ Nerve Impulse
Synapse: The release of a
chemical to allow an impulse to
travel from one neuron to
another neuron.

The Brain Stem
Internal View of the Brain
Receptors: A special sensory neuron
that receives information from the environment.
These receptors are found in your five sense
organs. – the skin, tongue, nose, eyes, and ear.
Taste Buds: Taste receptors on the surface of
your tongue bunched together in small round bumps.
Optic Nerve: The nerve that goes directly
between your eyes and your Occipital Lobe.
Auditory Nerve: Impulses travel to the brain
through this nerve to be processed in the brain.
Reflex: A simple behavior pattern involving
an automatic response to a stimulus. Allows
to react quickly to pain or danger.
