norepinephrine A neurotransmitter released from the axon ends of some nerve fibers; noradrenaline.
Some neurotransmitters are excitory, such as acetylcholine, norepinephrine, serotonin, and dopamine. Some are associated with relaxation, such as dopamine and serotonin. Dopamine release seems related to sensations of pleasure.
SNRIs (serotonin-norepinephrine reuptake inhibitors) work on the norepinephrine and serotonin neurotransmitters. Mirtazapine also increases levels of norepinephrine and serotonin, but it is a tetracyclic antidepressant, not a SSRI or SNRI.
When stimulated, the sympathetic fibres cause a release of norepinephrine
[NOTE] The international name for noradrenaline is now norepinephrine
Norepinephrine increases heart rate and strength of ventricular and atrial contraction ...
Noradrenaline (also called norepinephrine). Released by postganglionic neurons of the sympathetic branch of the autonomic nervous system. Also used at certain synapses in the CNS.
Dopamine. Used at certain synapses in the CNS.
Pertaining to nerves that release the neurotransmitter norepinephrine/noradrenaline (e.g. adrenergic nerves, adrenergic response). An alternative U.S. useage also pertains to the receptors acted upon by noradrenaline, i.e. adrenergic receptors.
in which S-methyl groups from methionine are converted into a biochemically reactive form through insertion into an adenosyl group; an active S-methyl group can be transferred from S-adenosylmethionine to acceptor molecules such as norepinephrine.
of the adrenal gland, that increases the concentration of glucose in the blood, raises blood pressure and heartbeat rate, and increases muscular power and resistance to fatigue; also one of the principal neurotransmitters; also called norepinephrine.
