Its a stimulatory and Inhibitory in nature..eg..it induces contraction of skeletal muscles fibres & inhibits contraction in cardiac muscle fibres.

∙ 11y agoNo GABA is not a catecholamine. The catecholamine family is made up of epinephrine (Called adrenaline in the United Kingdom), norepinephrine (Called noradrenaline in the United Kingdom) and dopamine. These neurotransmitters are derived from tyrosine and phenylalanine, while GABA is derived from glutamate. What is interesting is that GABA is the primary inhibitory mechanism in the nervous system, while glutamate is the primary excitatory mechanism in the nervous system.

What are the 3 components synapse?
acetylcholine catecholamines endorphins
What usually stimulates release of hormones from the adrenal medulla?
Sympathetic stimulation of the chromaffmin cells of the adrenal medulla stimulates the release of their catecholamines. The neurotransmitter is acetylcholine
What are biological amines?
a type of amine synthesized by plants and animals and frequently involved in signaling, e.g., neurotransmitters such as acetylcholine, catecholamines, and serotonin; others are hormones or components of vitamins, phospholipids, bacteria, or ribosomes, e.g., cadaverine, choline, histamine, and spermine...
Acetylcholine is an example of what neurotransmitter?
acetylcholine
Catecholamines are produced by what cells?
Chromaffin cells.
What are the 3 components synapse?
acetylcholine catecholamines endorphins
What usually stimulates release of hormones from the adrenal medulla?
Sympathetic stimulation of the chromaffmin cells of the adrenal medulla stimulates the release of their catecholamines. The neurotransmitter is acetylcholine
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
What are biological amines?

Catecholamines are derived from what?
tyrosine
What is an example of acetylcholine?
acetylcholine
Is serotonin a catecholamine?
no serotonin is not a catecholamine. Catecholamines are dopamine, epinepherine and norepinepherine.
Do Noncatecholamines cross the blood-brain barrier more readily than catecholamines?
Yes, noncatecholamines cross the BBB more readily than catecholamines, because noncatecholamines are less polarized than catecholamines.
Acetylcholine is an example of what neurotransmitter?
acetylcholine
What is the main neurotransmitter of the parasympathetic autonomic nervous system?
Parasympathetic system has acetylcholine as its chemical mediator.
The chemical that transmits the signal across the neuromuscular junction is called?
Acetylcholine
