TERMS TO KNOW
  • Threshold of Excitation

    The level or point at which a neuron fires, or a neural impulse is triggered.

  • Neuropeptides

    A special class of neurotransmitters that regulate the activity of neurons and systems in the brain.

  • Acetylcholine

    The most common neurotransmitter, which is used in movement in the peripheral nervous system and related to attention and memory in the brain.

  • Receptor Sites

    Areas on neurons that connect and respond to neurotransmitters.

  • Neurotransmitter

    Chemical messengers that allow neurons to communicate with other neurons across the synapse.

  • Synapse

    The small space between the axon terminal of one neuron and the dendrites of other neurons.

  • Action Potential

    The state in which a neuron reaches its Threshold of Excitation and fires, or sends an electrical impulse down the axon.

  • Resting Potential

    The state in which a neuron is not firing or sending a neural impulse and when there is a negative electrical charge inside the neuron.
