ipCD – Nervous II - Synaptic Potentials and Neurotransmitters

Benjamin Cummings. InterActive Physiology® 8-System Suite CD-ROM, Benjamin Cummings, 2004.

Objective:

To describe in a short essay or with diagrams the major features of synapses, the process of chemical synaptic transmission, and the role of excitatory and inhibitory neurotransmission and summation in the processing of nervous signals, at the level of 85% proficiency for each student.

 

In order to achieve this objective, you will need to be able to:

  1. Describe the location and anatomical features of synapses, including the presynaptic and postsynaptic components of the chemical synapse.
  2. Explain the process of synaptic transmission, including the role of actions potentials, fusion of synaptic vesicles, release of neurotransmitter, binding of neurotransmitter, and effects on ion channels.
  3. Compare and contrast inhibitory and excitatory neurotransmission.
  4. Explain the role of temporal and spatial summation of synaptic potentials in the cellular integration of nervous signals.
