Neural information controlling heart rate would travel
A) from the peripheral nervous system to the central nervous system.
B) from the central nervous system to the heart via autonomic efferents.
C) from the central nervous system to the heart via unconscious afferents.
D) to the central nervous system via hormones.
E) from the peripheral nervous system to the heart via conscious afferents

Question

Quizplus · Accepted Answer

The autonomic nervous system controls heart rate, and it is divided into the sympathetic and parasympathetic branches. The sympathetic nervous system, which is responsible for increasing heart rate, sends information to the heart via autonomic efferents that travel from the central nervous system to the heart. Therefore, choice B is the correct answer. Choices A, C, and D are incorrect because they involve the flow of information in the opposite direction or through different pathways. Choice E is also incorrect because conscious afferents do not control heart rate.
