  1. Biological Psychology
    The scientific study of the link between biological (genetic, neural, hormonal) and psychological processes.
  2. Neuron
    A nerve cell; the basic building block of the nervous system.
  3. Dendrite
    The neuron's bushy, branching extensions that recieve messages and conduct impulses toward the cell body.
  4. Axon
    The neuron's extension that passes messages through its branching terminal fibers that form junctions with other neurons, muscles, or glands.
  5. Action Potential
    A neural impulse; a brief electrical charge that travels down the axon.
  6. Threshold
    The level of stimulation required to trigger a neural impulse.
  7. Synapse
    The junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron. The tiny gap at this junction is called the Synaptic Cleft.
  8. Neurotransmitters
    Chemical messengers that cross the synaptic clefts between neurons. When released by the sending neuron, neuron transmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse.
