When impulses reach a synapse they trigger the release of chemicals called neurotransmitters. Molecules of the neurotransmitter cross the synapse and stimulate the receiving neuron to fire an impulse of its own as wave like movements of ions. They may also actively inhibit a receiving neuron from firing.

∙ 12y agoNeurotransmitters are the chemicals which allow the transition of signals to one neuron to the next- via a synapse. Chemicals that function as neurotransmitters include acetylcholine, norepinephrine, dopamine, serotonin, histamine, GABA, glutamate, endorphin, and nitric oxide. Neurotransmitters are typically synthesized in the cytoplasm of the synaptic knobs and stored in the synaptic vesicles.

Anagonist defininition in human anatomy?
A mimic of a neurotransmitter. Not the exact neurotransmitter, but works in the same way.
Which of these is the neurotransmitter associated with laughter?
Endorphins : "Humor involves the brain's reward system, which mainly uses dopamine as its neurotransmitter."
The effect of a neurotransmitter on the postsynaptic cell occurs when the neurotransmitter?
binds to specific receptors on postsynaptic cell membrane
What specific neurotransmitter is released from the axon terminus?
You do not have single neurotransmitter, which is released from axon terminals. There are many. Some facilitate the conduction of the impulse and others inhibit the same. You have acetylcholine, norepinephrine, dopamine and many others acting as neurotransmitter.
What neurotransmitter functions as a common inhibitory neurotransmitter in the brain?
GABA (Gamma-AminoButyric Acid) is the most common neurotransmitter producing inhibition in the brain.
What determines whether a neurotransmitter will have an inhibitory excitatory effect?
How a neurotransmitter interacts with the receptors determines its effects. They activate receptors to perform specific functions in the body.the type of receptor
Curare is a paralyzing poison that functions as what?
It functions as an Acetylcholine antagonists. Acetylcholine was the first neurotransmitter to be discovered. A nicotinic antagonist inhibits Acetylcholine's receptors.
How do signal molecules change how a cell will function?
Signal molecules act as a neurotransmitter or a hormone, which both effect how a cell functions.
The neurotransmitters acetylcholine performs what two functions?

acetylcholine
What do you call the chemical released by the axon that travels across a synapse and binds on the dendrites of the other neurons or body cells?
neurotransmitter neurotransmitter neurotransmitter
What is the functions of neurotransmitter?
The neurotransmitters are stored in tiny sac-like structures called vesicles at the end of axons. When an impulse, or nerve signal, reaches the end of the axon, the vesicles release a neurotransmitter into the small space between the adjoining cells (synaptic gap). Neurotransmitters diffuse across the synapse and bind to receptors in the receiving cell that are specific for the neurotransmitter.
Is GABA a hormone?
GABA is a neurotransmitter, it is the primary inhibitory neurotransmitter of the nervous system
