Study Notes
Baroreceptor Reflex Control of Blood Pressure
- Baroreceptors are specialized sensory receptors located in the aorta and carotid arteries, vital for blood pressure regulation.
- Action potentials generated by baroreceptors are transmitted to the brain through the vagus and glossopharyngeal nerves.
- The vagus nerve is responsible for conducting action potentials from the brain back to the heart.
- A decrease in parasympathetic stimulation does not lead to decreased heart rate and stroke volume; the statement is false.
- Increased sympathetic stimulation does not cause vasodilation; rather, it typically leads to vasoconstriction, which raises blood pressure. The statement pronouncing it as true is false.
