Neurotransmitter

Neurotransmitter(Shin Tadasu Musetto,: Neurotransmitter) is a substance mediating information transmission in. Synaptic cells have a neurotransmitter synthesis system, and postsynaptic cells have neurotransmitters. Neurotransmitters are inactivated after release. Zinc ions affecting postsynaptic cells are neurotransmitters in the broad sense. Is also an intercellular mediator that binds to the receptor. The neurotransmitter acts locally, and the hormone acts globally through circulatory system and the like. It has the same effect.

before release

Neurotransmitters are synthesized in pre-cells and are either carried by cell transport or absorbed from the outside and are stored at the end of the presynaptic process. Neurotransmitters are released to the presynaptic terminal when it reaches the end.

after release

When released into the neurotransmitter, it spreads by and is activated in association with receptors on postsynaptic cells. If the receptor is a type, it opens and if the receptor is a metabolic form, it will be opened through several steps afterwards, causing the postsynaptic cells to become absent. After release, it is inactivated promptly or reconstituted at the presynaptic terminal and part is again stored in synaptic vesicles and recycled (not to return to the original synaptic vesicle but to another synaptic vesicle It is filled in the cell).

Classification

Neurotransmitters can be broadly classified into the following three.
