Presentation Transcript

    1. What is a synapsis

    2. The Synapse Junction between two cells Site where action potentials in one cell cause action potentials in another cell Types Presynaptic Postsynaptic

    3. Electrical Synapses Gap junctions that allow local current to flow between adjacent cells Found in cardiac muscle and many types of smooth

    4. Chemical Synapses Components Presynaptic terminal Synaptic cleft Postsynaptic membrane Neurotransmitters released by action potentials in presynaptic terminal Synaptic vesicles Diffusion Postsynaptic membrane Neurotransmitter removal

    5. More about synapsis

    6. Synapsis

    7. Neurotransmitters and neuropeptides

    8. Postsynaptic Potentials Excitatory postsynaptic potential (EPSP) Depolarization occurs and response is stimulatory Depolarization might reach threshold producing an action potential and cell response Inhibitory postsynaptic potential (IPSP) Hyperpolarization and response is inhibitory Decrease action potentials by moving membrane potential farther from threshold

    9. Nerotransmitters and Neuromodulators

    10. Neurotransmitters etc.

    11. Criteria for neurotransmitters

    12. Types of neurotransmitters

    13. Types of neurotransmitters

    14. Transport and release of neurotransmitters

    15. Binding and inactivation of neurotransmitters

    16. Inactivation of neurotransmitters

    17. Neurotransmitter Removal

    18. Spatial and Temporal Summation

    19. Summation
