There are three of neurons:
afferent , efferent neurons and
. Afferent neurons are
that only transmit
information from the to neural
nuclei ganglia (where they
connection with interneurons effector
neurons). Efferent are those
that commands to tasks
in several parts the body.
Interneurons, known as association
or relay neurons, as
connection between other neurons.

Afference the conduction of
impulses and efference the
conduction of impulses
(impulses that some body
action).
