it would be postganglionic sympathetic fibers
What else can I help you with?
Which of the following neurotransmitter is a catecholamine?
Dopamine, norepinephrine, and epinephrine are catecholamines.
What neurotransmitter is in the locus coeruleus?
The locus coeruleus predominantly releases the neurotransmitter norepinephrine (noradrenaline). This neurotransmitter plays a key role in the regulation of arousal, attention, and the stress response.
Are catecholamines water insoluble?
Catecholamines are soluble in water.
What are the differences between catecholamines and non catecholamines?
catecholamines are chemical transmitters,polar compounds readily oxidized has catechol rings and amines such as dopamine nor-epinpherene and serotenie non- catecholamines with out catechol rings
Into what does the neuron release its neurotransmitter at the neuromuscular junction?
The neuron releases its neurotransmitter into the synaptic cleft at the neuromuscular junction, which is the gap between the neuron terminal and the muscle cell. This neurotransmitter then binds to receptors on the muscle cell membrane, triggering muscle contraction.
Norepinephrine dopamine and epinephrine belong to a group of neurotransmitters known as?
catecholamines
What part of neuron releases neurotransmitter my choices are axon axon terminal dendrite myelin sheath or cell body?
The neurotransmitter is released from the axon terminal.
The sympathetic nervous system releases the neurotransmitter?
Norepinephrine (otherwise known as Noradrenaline). Acetylcholine IS NOT the right answer.
When one neuron wants to stimulate another it will?
A neuron releases a chemical called a neurotransmitter that will signal other neurons.
What gland produces catecholamines?
"Catecholamines are produced mainly by the chromaffin cells of the adrenal medulla and the postganglionic fibers of the sympathetic nervous system. Dopamine, which acts as a neurotransmitter in the central nervous system, is largely produced in neuronal cell bodies in two areas of the brainstem: the substantia nigra and the ventral tegmental area. The similarly melanin-pigmented cell bodies of the locus ceruleus produce norepinephrine." - WikipediaThe main catecholamines are epinephrine and norepinephrine, which are produced in the adrenal medulla (in the adrenal glands). Dopamine is the other, which is from neuronal cell bodies.
What kind of potential is it when a neuron fires?
When a signal is sent out from the nervous system it is caused a release of a neurotransmitter that releases an action potential.
Catecholamines are derived from what?
tyrosine
