|
|
Term
|
Definition
| a region where nerve impulses are transmitted and received, encompassing the axon terminal of a neuron that releases neurotransmitters in response to an impulse, an extremely small gap across which the neurotransmitters travel |
|
|
Term
|
Definition
| any of several chemical substances that transmit nerve impulses across a synapse to a postsynaptic element, as another nerve, muscle, or gland. |
|
|
Term
|
Definition
| the effect the postsynaptic neuron has, which is dependent on the neurotransmitters delivered from presynaptic neuron |
|
|
Term
| Excitatory Post Synaptic Potenial |
|
Definition
| post synaptic potential are called excitatory if they increase the likelihood of a postsynaptic action potential occurring |
|
|
Term
| Inhibitory post synaptic potential |
|
Definition
| inhibitory if they decrease this likelihood of a post synaptic action potential occuring |

|
|
Term
| parasympathetic nervous system |
|
Definition
| The part of the autonomic nervous system originating in the brain stem and the lower part of the spinal cord that, in general, inhibits or opposes the physiological effects of the sympathetic nervous system, as in tending to stimulate digestive secretions or slow the heart. |
|
|
Term
| sympathetic nervous system |
|
Definition
| The part of the autonomic nervous system originating in the thoracic and lumbar regions of the spinal cord that in general inhibits or opposes the physiological effects of the parasympathetic nervous system, as in tending to reduce digestive secretions or speed up the heart. |
