herat rate incresa
Stimulation of the reticular formation results in increased consciousness.
When the aortic semilunar valve snaps shut, a momentary increase in the aortic pressure results from the elastic recoil of the aorta after valve closure.
An expansion of the aortic vein
The medulla oblongata. Blood pressure is monitored via baroreceptors. When BP is high, baroreceptors in the carotid sinus and aortic arch is stimulated, stimulating them to fire off action potential via afferent nerve (vagus and glossopharyngeal) to the medulla. This inbhits the sympathetic and activates the parasympathetic nervous system. Activation of the parasympathetic nervous sytem means that the vagus nerve produces more ACh to decrease the heart rate. Inactivation of the sympathetic means that the cardioaccelatory and vasomotor nerves are inhibited, therefore, heart rate will decrease and vasodilation.
A pengina is a cross between a penis and a vagina. a penis united with a vagina does not need outside stimulation when one becomes asexual due to a lack of sexual relations with others the subsequent auto stimulation of the pengina results in a libidinal equilibrium in which one no longer craves nor even thinks about sex
Arterial = aortic and carotid sinuses. There are also atrial, ventricular and pulmonary baroreceptors
baroreceptors
changes in arterial pressure
yes
negative feedback via baroreceptors in the carotid artery and aortic arch
Stimulation of the reticular formation results in increased consciousness.
When the aortic semilunar valve snaps shut, a momentary increase in the aortic pressure results from the elastic recoil of the aorta after valve closure.
Baroreceptors
A baroreflex is a reflex which results from stimulation of a baroreceptor.
They detect the blood pressure of the internal environment and send the results to the CNS, where it will react in several different ways
false
A reflex.
