Document Summary
Directed and non directed synapses - look more at that. There are proteins devoted to this and they"re called snare proteins. Interfering with this processes can affect neurotransmitter release. Once they"re released into the synaptic cleft then it sticks to the membrane to the post synaptic cell. contains the binding site for a speci c neurotransmitter(lignad) its like a lock and key one works for one. But a puzzle piece works better because they bind with multiple cites. its like real puzzles too because they can sometimes bind to the same site when they shouldn"t. Receptor subtypes - the different receptors have different effects on the postsynaptic cell. These determine the function of a certain neurotransmitter. Its not just important to talk about a neurotransmitter but also the receptor. The same neurotransmitter can have different function in different regions. Eg: membrane receptors: inotropic and metatropic. cytosol or nucleus ligand activated ion channel. Eg: inotropic: excitatory postsynaptic potentials (depolarization) often na.
