Nervous System - Part 3 Flashcards
What type of transmission is the transfer of signals from one neuron to another?
Synaptic
What type of synapses is gap junctions between cells for exchange of ions?
Electrical
What type of synapses involves release of neurotransmitter from presynaptic terminals into the synaptic space and binding of the neurotransmitter to the receptor in the postsynaptic membrane- opening of channels in the target cell and depolarization?
Chemical
What are glutamate and y-aminobutryric acid (GABA) classified as?
Amino acids
What are dopamine, norepinephrine, and epinephrine classified as?
Catecholamines
What is acetylcholine classified as?
Choline
What step is the action potential during the release of neurotransmitters?
Step 1
What step is increased calcium permeability at the axon terminal during the release of neurotransmitters?
Step 2
What step is vesicle fusion with presynaptic membrane during the release of neurotransmitters?
Step 3
What step is NT release during the release of neurotransmitters?
Step 4
What is the fusion of synaptic vesicles with the presynaptic membrane mediated by?
“Docking” proteins of the snare complex
What 2 molecules are synthesized and recycled during the excitatory?
Acetylcholine and glutamate
What comprises a terminal branch of the motor end plate and the sacrolemma?
Neuromuscular synapse
What receptors are ligand-gated sodium channels located in the sacrolemma?
Nicotinic cholinergic
What breaks excess ach into choline and acetate?
AChE
