How It Works
 The cells of the nervous system are comprised of three
types of neurons.
 Sensory neurons- carry impulses or sensations from receptors
(located in the skin, skeletal muscles, joints, and internal
organs) to the brain or spinal cord.
 Motor neurons- carry impulses from the brain or spinal cord to
muscles and glands, causing muscles to contract and glands
to secrete.
 Interneurons- located in the CNS and conduct impulses from
sensory to motor neurons
 Each neuron carries impulses in only one direction to
prevent impulses canceling each other.
 Impulses are transmitted via electrochemical reactions
that occur at the synapses (tiny space between the
dendrite of one cell and the axon of another cell.
 Sodium/Potassium gates as well as neurotransmitters
cause this electrochemical reaction. Many drugs
effectiveness are based on their ability to mimic or block
secretion/uptake of certain neurotransmitters
