Function of Nerve Cells or Neurons

 Transmit information by electrochemical signals

from sensory receptors

to the Brain and

from the Brain

to the Effectors (muscles, organs, glands) that control their activity

Axon

Long fiber in the nerve cell body through which the dendrites route electrochemical signals from other nerves to the next nerve cell, organ or muscle

Dendrite

 Short thin processes that come off the nerve cell body of a neuron

Collects electrochemical signals from other nerves and route them through the nerve cell body and down the axon to the next cell, organ or muscle
