Neuron : the nerve cells that transfer information within the body.
Neurons can be placed into three groups, based on their location and function.Sensory neurons, interneurons, motor neurons.
sensory neuron :Transmit information from a sense receptor to the brain or spinal cord
interneuron:Integrate information within brain or spinal cord; connect sensory and motor neurons; located entirely within the CNS
motor neuron:Transmit information from the brain or spinal cord to a muscle or gland; Cause muscle contraction or gland secretion
