Sympathetic nervous system .
Andrenergic fibers release Norepinephrine and Cholinergic fibers release Acetylcholine.
Sweat glands are innervated by adrenergic sympathetic nerve fibers from the autonomic nervous system. These fibers release norepinephrine, which stimulates the sweat glands to produce sweat.
Yes, when stimulated the sympathetic postganglionic fibers release norepinepherine (20%) and epinepherine (80%).
Norepinephrine is mainly secreted by the adrenal medulla and the postganglionic fibers of the sympathetic nervous system, which are also known as adrenergic fibers. These fibers release norepinephrine in response to stress or arousal, helping to initiate the body's fight or flight response.
Preganglionic fibers of the autonomic nervous system typically run from the central nervous system to an autonomic ganglion outside the central nervous system, where they synapse with postganglionic neurons. These fibers are part of the efferent pathway that transmits signals from the central nervous system to the peripheral organs and tissues.
yes.
The enzyme responsible for breaking down norepinephrine in nerve fibers is called monoamine oxidase (MAO). It degrades norepinephrine into its metabolites to regulate neurotransmission and maintain balance in the nervous system.
The autonomic fibers are contained within the ventral (anterior) root of the spinal nerve. These fibers are responsible for carrying signals to and from the autonomic nervous system, which controls involuntary bodily functions.
The parasympathetic nervous system has long preganglionic and short postganglionic fibers
yes , true! sympathetic nervous system releases norepinephrine,epinephrine, dopamine neurotransmitters which stimulate adrenegic fibers and produce "fight or flight" so that you can fight that bear!
No, postganglionic fibers release norepinephrine, not epinephrine. Epinephrine is released by the adrenal medulla.
