Temperature regulation is managed by a
A) single system in the hypothalamus.
B) single system in the spinal cord.
C) hierarchy of systems extending from the spinal cord to the hypothalamus.
D) hierarchy of systems extending from the medulla to the spinal cord.

Question

Quizplus · Accepted Answer

Temperature regulation involves a hierarchy of systems that extend from the spinal cord to the hypothalamus. The peripheral receptors in the skin and body organs signal the local temperature to the spinal cord, which then integrates and sends the information to the hypothalamus. The hypothalamus is considered the master control center for temperature regulation, but it is not a single system as it involves multiple structures and pathways, including the preoptic area, anterior hypothalamus, and posterior hypothalamus. Therefore, option A and B are incorrect, and option D is partly correct but incomplete.
