Why is the cardiovascular center in the medulla as opposed to the same cortical, hypothalamic, or thalamic area?

Solution

thte cardiovascular is the part of brain which is responsible for the regulation of the rhythymisity of herat and heart beat.generally the herat beat doesnt required any stimuli that means it not required nerve stimulation but in certain condition it is requireed stimulation theough the nerve. Cardiovascular center contains three different components: the vasomotor center, cardioaccelerator center, the cardioinhibitor center,

cardioacceleratoe center is responsible for the stroke volume in herat by the regulation of the sympathatic system.

cardioinhibitoey center are responsible for the negative regulation of the herrat, it decrease force of contraaction and stoke volume via parasympathatic system.

the vasomotor center control the tunes of vesseles or contraction of smooth muscle in tunica media.

changes in the diameter affects the peripheral resistance, pressure,and flow which also affects the cardiac output. it caused stimulation or this parameter act as stimuli for the cardic receptor to control the changes it send the msg to the cardiac sysem accroding to need. it is generally done with the sympathatic system and parasympathatic system means by adrenalin or by acetylcholin. the hormone regulation is done by autofeedback system mediated theough the hypothalamus or thalamus region.

the cardio vasscular center responds to the numerous stimmuli like hormone such ass epinephrine, and norepinefrine, physical stimuli, posture stimuli, changes in ph due to enhanced concentration of carbon dioxide, pressure stimuli, baroreceptor changes, chemoreceptor changes. for the sensing of the above listed stimuli it is opposite to the thalamus or hypothalamus, and also hypothalamus is the part responsible for the secreation of various hormon accroding to the automated feedback system. so thats why it should b
