Vasoconstrictor

a. (Physiol.) Causing constriction of the blood vessels; as, the vasoconstrictor nerves, stimulation of which causes constriction of the blood vessels to which they go. These nerves are also called vasohypertonic. [ 1913 Webster ]

Vasoconstrictor

n. (Medicine, Physiology) A substance which causes constriction of the blood vessels. Such substances are used in medicine to raise abnormally low blood pressure. [ PJC ]

Vasodentine

n. [ L. vas a vessel + E. dentine. ] (Anat.) A modified form of dentine, which is permeated by blood capillaries; vascular dentine. [ 1913 Webster ]

Vasodilator

n. [ L. vas a vessel + dilator. ] (Medicine & Physiology) A substance which causes dilation of blood vessels. [ PJC ]

Vasodilator

a. [ L. vas a vessel + dilator. ] (Physiol.) Causing dilation or relaxation of the blood vessels; as, the vasodilator nerves, stimulation of which causes dilation of the blood vessels to which they go. These nerves are also called vaso-inhibitory, and vasohypotonic nerves, since their stimulation causes relaxation and rest. [ 1913 Webster ]

Vasoformative

a. [ L. vas a vessel + formative. ] (Physiol.) Concerned in the development and formation of blood vessels and blood corpuscles; as, the vasoformative cells. [ 1913 Webster ]

Vasohypertonic

a. [ See Hyper-, and Tonic. ] See Vasoconstrictor. [ 1913 Webster ]

Vasohypotonic

a. [ See Hypo-, and Tonic. ] See Vasodilator. [ 1913 Webster ]

Vaso-inhibitory

a. (Physiol.) See Vasodilator. [ 1913 Webster ]

Vasomotor

a. [ L. vas a vessel + motor that which moves fr. movere to move. ] (Physiol.) Causing movement in the walls of vessels; as, the vasomotor mechanisms; the vasomotor nerves, a system of nerves distributed over the muscular coats of the blood vessels. [ 1913 Webster ]

Vasomotor center, the chief dominating or general center which supplies all the unstriped muscles of the arterial system with motor nerves, situated in a part of the medulla oblongata; a center of reflex action by the working of which afferent impulses are changed into efferent, -- vasomotor impulses leading either to dilation or constriction of the blood vessels. [ 1913 Webster ]
