Nervous System I and II Interactive Physiology Modules

     Most of the material covered in these two modules on the CD and the corresponding chapters in your Germann and Stanfield textbook was covered in BSCI 230 and will be familiar to you.  The following list of terms is provided to insure that you understand all of the concepts that will utilized in BSCI 440:
 

    • Current

    • Voltage

    • Resistance and conductance

    • Ion gradients across cell membrane

    • Ohm’s law

    • Voltage-gated ion channels

            • K+  channels

            • Na+ channels

    • Electrical and concentration gradients

    • Selectively permeable membranes

    • Membrane potential (V_m)

    • Depolarization

    • Hyperpolarization

    • Threshold

    • Action potential

            • Rising phase (depolarization)

            • Falling phase (repolarization)

            • Ionic basis of AP

    • Conduction velocity

    • Myelination & Schwann Cells

    • Synaptic transmission & neurotransmitters

    • Exocytotic release of neurotransmitter

    • Synaptic currents

    • Post synaptic potentials

            • IPSP

            • EPSP

    • Temporal and spatial summation

    • Mechanisms of signal transduction

            • Ligand-gated ion channels

            • G proteins

            • Adenylyl cyclase & cyclic AMP

            • IP3

            • Protein kinases
 

If you understand these concepts and can work the membrane potential problems using the Nernst and Goldman Constant Field equations, you will do well on that part of Exam I.
