Definition that contains vasoconstriction
- ischemia local anemia in a given body part sometimes resulting from vasoconstriction or thrombosis or embolism
- alpha-adrenoceptor receptors postulated to exist on nerve cell membranes of the sympathetic nervous system in order to explain the specificity of certain agents that affect only some sympathetic activities (such as vasoconstriction and relaxation of intestinal muscles and contraction of smooth muscles)
- vasopressor any agent that produces vasoconstriction and a rise in blood pressure (usually understood as increased arterial pressure)
- alpha receptor receptors postulated to exist on nerve cell membranes of the sympathetic nervous system in order to explain the specificity of certain agents that affect only some sympathetic activities (such as vasoconstriction and relaxation of intestinal muscles and contraction of smooth muscles)
- ischaemia local anemia in a given body part sometimes resulting from vasoconstriction or thrombosis or embolism
- alpha-adrenergic receptor receptors postulated to exist on nerve cell membranes of the sympathetic nervous system in order to explain the specificity of certain agents that affect only some sympathetic activities (such as vasoconstriction and relaxation of intestinal muscles and contraction of smooth muscles)
