What is the primary function of the afferent signals sent to the CNS from baroreceptors?
Understand the Problem
The question is asking about the role of afferent signals from baroreceptors in relation to the central nervous system (CNS). Specifically, it seeks to identify which action these signals primarily facilitate — either stimulating or inhibiting various autonomic nervous system activities.
Answer
Regulate heart rate, peripheral resistance, and cardiac output.
The primary function of the afferent signals sent to the CNS from baroreceptors is to inform the autonomic nervous system about changes in blood pressure, which helps regulate heart rate, peripheral resistance, and cardiac output.
Answer for screen readers
The primary function of the afferent signals sent to the CNS from baroreceptors is to inform the autonomic nervous system about changes in blood pressure, which helps regulate heart rate, peripheral resistance, and cardiac output.
More Information
These signals are part of the baroreceptor reflex, which is crucial for short-term blood pressure regulation and helps maintain homeostasis.
Tips
A common mistake is to confuse the role of baroreceptors with chemoreceptors, which are involved in chemical signaling and not mechanical changes like blood pressure.
