BIOL 3310 Lecture Notes - Lecture 6: Vasomotor Center, Inosculation, Vasomotor
Document Summary
Neurogenic seismic disturbance loss of vasomotor tone leading to vasodilation - due to prob with brain fore / medulla oblongata oblongata. Venous inosculation when 2 veins merge most common anastomosis provides replacement routes for drain. Examples of chemore exes hypoxemia, hypercarbia (too much co2), and acidosis stimulate chemoreceptor - instruct vasomotor nitty- gritty to cause constriction, which bp, lung perfusion and gas exchange. Most green / simple circulation route tenderness arteries arterioles capillary tube venules veins heart. Medullary ischemic unconditioned re ex inadequate perfusion of the mentality stem - cardiac and vasomotor shopping center send sympathetic signals to heart and vessels, addition ow to brain by increasing cardiac output. Transient ischemic flak ischaemia that "comes and goes" - dizziness, loss of vision, weakness, paralysis, headache - shoemaker"s last minute of arc to hours - early warning side of impending stroke.
