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.
A substance which causes constriction of the blood vessels. Such substances are used in medicine to raise abnormally low blood pressure.
an agent (such as a sympathetic nerve fiber or a drug) that induces or initiates constriction of blood vessels
relating to a process, condition or substance that causes a narrowing of an opening of a blood vessel
chemical or drug that constricts arteries, reducing blood flow to an organ or tissue.
any substance that constricts or narrows blood vessels.
Substance that cause the narrowing of a blood vessel
any agent that causes a narrowing of an opening of a blood vessel: cold or stress or nicotine or epinephrine or norepinephrine or angiotensin or vasopressin or certain drugs; maintains or increases blood pressure
a substance that causes cells in the brain or body to get smaller, which means less blood gets to the cell (as the cell is smaller)
a substance that constricts blood vessels
An agent that causes constriction of blood vessels. This reduces local blood flow to an area, and temporarily raises blood pressure.
causes small blood vessels to contract.
Any chemical substance, such as epineplrrine, which keeps the anaesthetis in the area by diminishing the blood flow into or out of an area. An added advantage is it restricts bleeding during surgical procedures.
Constricts the blood vessels.
vasomotor system the component of the nervous system that controls the dialation and contraction of blood vessels
A chemical substance whose actions result in the narrowing of blood vessels.
Contracts the blood vessel walls
A drug or hormone that causes constriction of the blood vessels.
a nerve or drug, that causes constriction of a blood vessel
An agent causing the contraction of blood vessel walls
Constricts and narrows blood vessels
A substance, such as a nerve or a drug, that causes blood vessels to narrow.
Affects nervous system and nerve function due to its ability to constrict the blood vessels, thereby raising blood pressure.
Capable of tightening the walls of blood vessels.
An agent that causes blood vessels to constrict, or narrow the caliber.
causes narrowing of blood vessels
A nerve, agent or substance that narrows blood vessels.
A vasoconstrictor, also vasopressor or simply pressor, is any substance that acts to cause vasoconstriction (narrowing of the lumena of blood vessels) and usually results in an increase of the blood pressure. The opposite process, vasodilation, is the opening of blood vessels. Vasoconstrictors are used in medicine to treat hypotension.
