A state of shock as a result of generalized vasodilation, produced by action of the nervous system.
A state of shock caused by bad news or an unpleasant surprise.
A form of distributive shock due to decreased peripheral vascular resistance. Damage to either the brain or the spinal cord inhibits transmission of neural stimuli to the arteries and arterioles, which reduces vasomotor tone. The decreased peripheral resistance results in vasodilation and hypotension; cardiac output diminishes due to the altered distribution of blood volume.
