A decrease in diameter is called bronchoconstriction and is stimulated by histamine, parasympathetic nerves, cold air, chemical irritants and other factors to decrease air flow.
12.
Just after the facial nerve geniculate ganglion ( general sensory ganglion ) in the temporal bone, the facial nerve gives off two separate parasympathetic nerves.
13.
Contrary to popular belief, erectile function is not compromised by RPLND because the nerves responsible for erection are located elsewhere ( parasympathetic nerves from S2-S4 ).
14.
The mucous membranes receive their postganglionic parasympathetic nerve innervation for mucous secretion originating from the greater petrosal nerve ( a branch of the facial nerve ).
15.
The parasympathetic nerve supply comes from the parasympathetic preganglionic neurons in the sacral spinal cord and also terminates in the longitudinal and circular smooth muscle layers.
16.
Salt gland activations occurs from increased osmolarity in the blood, stimulating the hypothalamic information processing, sending signal through the parasympathetic nerve activating vasodilation, the release of hormones ( acetylcholine and vasoactive intestinal peptide ).
17.
The mucous membrane in this sinus is innervated by the supraorbital nerve, which carries the postganglionic parasympathetic nerve fibers for mucous secretion from the ophthalmic nerve and supplied by the supraorbital artery and anterior ethmoidal artery.
18.
He cited two reports to be issued soon that document a sharp increase in sudden deaths in the hours and days after 9 / 11 in people wearing heart monitors that revealed a near-disappearance of protection afforded by parasympathetic nerves.
19.
Stretch receptors in the walls of the parasympathetic nerves to beat more slowly ( called bradycardia ), ensuring that the inflow of blood into the arteries is reduced, thus adding to the reduction in pressure, and correction of the original error.
20.
Its smooth muscle is innervated by involuntary nerves ( sympathetic nerves via the sympathetic trunk and parasympathetic nerves via the vagus nerve ) and in addition voluntary nerves ( lower motor neurons ) which are carried in the vagus nerve to innervate its striated muscle.
