1.1 NEUROTRANSMISSION
-
: 
HOW?
- A.P arrive at end bulb post sypnatic neuron.
- A.P depolarizes Ca :arrow_right: Ca voltage gated channel open :arrow_right: Ca ion into presynaptic neuron end bulb
- :arrow_up: conc Ca ion :arrow_right:exocytosis synaptic vesicles :arrow_right: release neurotransmitter into synaptic cleft
- N.T bind to N.T receptor on ligand gated channel at POSTSYNAPTIC NEURON
- allow ions into postsynaptic neuron
- VOLTAGE ACROSS MEMB CHANGES depend on ion flows
-
-
- When depolarization reaches threshold :arrow_right A.P triggers
