Baroreceptor reflex control
- Baroreceptors in carotid aortic bodies detect changes in BP.
- Impulses are conducted to cardio regulatory and vasomotor control centers in medulla oblongata via Glossopharyngeal (IX) and Vagus (X) Nerves
- ^ BP will cause parasympathetic stimulation of heart, which decrease HR
- ^ BP will cause decrease sympathetic stimulation of hear, which decreases HR.
- ^ BP will cause vasomotor center to decrease sympathetic stimulation to BV, causing vasodilation.
