• Process of Neurotransmitter Release

  475623 Process of Neurotransmitter Release Explain the process a neuron undergoes when going from a resting potential to an action potential to the release of its neurotransmitters.

• Describe the physiology of depolarization and repolarization.

  It hops as an electrical current from one node to the next. This speeds up action potential travel down an axon about 20 fold as compared to axons lacking myelin.

• Neural Tissues and the Action Potential

  from which a neural action potential can be transmitted.

• Mechanisms and Enzymes - Synaptic cleft & Neurotransmitters

  When an action potential travels to the synapse, the rapid depolarization causes calcium ion channels to open.

• Factors Affecting Action Potentials

  However, an inhibitory neurotransmitter causes hyperpolarization of the membrane potential. This usually results from chloride channels being opened and chloride ion flowing into the cell, making the inside more negative.

• Myelin for action potential propagation.

  As a result, what do you think will happen to neurons and their ability to induce an action potential from the beginning of the cell body to the end of an axon, if myelin is lost as it is in multipple sclerosis?

• Neuron Transmission

  This causes the inside of the cell to become more positive, and hence the effect is depolarizing. If enough of this occurs, the membrane potential will reach threshold and trigger an action potential.

• Drugs' neurological effects on the brain

  When one neuron fires an action potential, it releases neurotransmitters into the synaptic cleft which then technically are supposed to bind to the next neuron's binding sites and create the behavior common to that specific neurotransmitter.

• How Neuro Processes Affect Behavior and Impact the Field of Biological Psychology

  Within these areas are synaptic vessels that hold many molecules of the neurotransmitter. Transport proteins fill vesicles with the neurotransmitter and then trafficking proteins are involved in the release of the neurotransmitter (Carlson, 2007).
