3 ways to clear Neurotransmitters from cleft
|
1. diffuse away
2. Ach Esterase 3. Transporter (Na symport) coccaine = dopanmine transporter inhibiter |
|
two NT receptor types are?
|
1. Ionotropic Receptor
- one channel/2 NT - e.g. nicotinic receptor (skeletal muscle) 2. Mechanotropic R (G protein) - cascade, and more spots for regulation |
|
What is EPSP mean?
|
Excitatory Post Synaptic Potential. During a post synaptic response the cell depolorizes to -15mV. This is due to both g(NA) and g(K) increasing but g(NA) goes up by 1.25

Example of NT being an IPSP or EPSP
|
Ach.
muscular-> EPSP heart-> IPSP |

Difference between Nerve-Nerve vs. Nerve-Muscle is?
|
Nerve
-up to 200k synapses -Axon Hillock -temperol and spatial summation Muscle -One nerve synapse - more sensitive - can't have spatial summation |
