A neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse. The cell receiving the signal, or target cell, ...
Synthesis of the neurotransmitter. This can take place in the cell body, in the axon, or in the axon terminal. Storage of the neurotransmitter in storage granules or vesicles in the axon terminal. Calcium enters the axon terminal during an action potential, causing release of the neurotransmitter into the synaptic cleft.
The neurotransmitters of postganglionic fibers differ: In the parasympathetic division, neurons are cholinergic.That is to say acetylcholine is the primary neurotransmitter responsible for the communication between neurons on the parasympathetic pathway.
A neurotransmitter is a type of molecule that carries signals between neurons (nerve cells) at synapses in the nervous system The main article for this category is Neurotransmitters . Wikimedia Commons has media related to Neurotransmitters .
In a neuron, synaptic vesicles (or neurotransmitter vesicles) store various neurotransmitters that are released at the synapse. The release is regulated by a voltage-dependent calcium channel . Vesicles are essential for propagating nerve impulses between neurons and are constantly recreated by the cell .
Neurotransmitter transporters are a class of membrane transport proteins that span the cellular membranes of neurons. Their primary function is to carry neurotransmitters across these membranes and to direct their further transport to specific intracellular locations. There are more than twenty types of neurotransmitter transporters. [1]
Neuropeptide Y is a neurotransmitter (brain chemical) that stimulates appetite. It aids in the storage of calories as fat and reduces the rate at which energy is burned.
Epinephrine, also known as adrenaline, is a monoamine neurotransmitter that plays in fight-or-flight response, increases blood flow to muscles, output of the heart, pupil dilation, and glucose. Serotonin is a monoamine neurotransmitter that plays a regulatory role in mood, sleep, appetite, body temperature regulation, and other processes.
