n
(physiology) A special manifestation of the myogenic tone in the vasculature, whereby in the event that blood pressure is increased in the arterioles and the vessels distend, they react with a sudden vasoconstriction caused by the activation of certain ion channels in the vascular smooth muscle cells.
n
Less than the normal degree of vasculation
n
excitation of, or by means of the sympathetic nervous system
adj
Stimulating the vagus nerve.
adj
(physiology, medicine) Active on vessel walls, that is, causing either constriction or dilation of a blood vessel, thus affecting hemodynamics (blood flow).

adj
That causes vasoconstriction
adj
That undergoes vasoconstriction
n
The lowering of blood pressure
n
(biochemistry) Any material that mediates the vascular system
n
Anything that leads to vasoregulation
n
The stimulation of vasomotor action.
adj
(medicine) Improving venous tone.
