Bp regulation

Which nerve is the afferent for carotid sinus baroreceptors?

• Vagus Nerve

• Olfactory nerve

• Facial nerve

• Glossopharyngeal nerve

What is the most powerful activator of the sympathetic vasoconstrictor system?

• Baroreceptors response

• None of the above

• Chemoreceptors response

• CNS ischemic response

What is the main role of chemoreceptors in the body?

• Regulating heart rate

• Detecting changes in oxygen levels

• Controlling muscle contractions

• Monitoring blood pressure changes

What happens when the mean arterial pressure drops below 60 mmHg?

• Baroreceptors response is inhibited

• CNS ischemic response is triggered

• Chemoreceptors are activated

• Blood flow to the brain increases

Why doesn't the parasympathetic nervous system innervate the blood vessels?

• It cannot cause vasoconstriction

• It only innervates the heart

• It is not involved in regulating blood pressure

• It lacks the necessary neurotransmitters

What is the threshold for activation of Type C baroreceptors?

• Low

• High

• Moderate

• Variable

What is the response of chemoreceptors when blood flow is reduced?

• They remain unaffected

• They are stimulated

• They are inhibited

• They become less sensitive

What is the role of CNS ischemic response in the body?

• To regulate blood pressure

• To dilate blood vessels

• To prevent further decrease in MAP

• To increase heart rate

What is the function of the vasomotor center in the medulla oblongata?

• To process visual information

• To maintain blood pressure

• To regulate breathing

• To control muscle movements

What is the purpose of the abdominal compression reflex?

• To regulate blood pressure in the abdomen

• To increase blood flow to the brain

• To maintain venous pressure

• To prevent hypoxia in the muscles
