Textbook Problem

Which structure and function are correctly paired below?

a. thalamus: relays emotion signals through the limbic system

b. basal nuclei: relay inputs from odor receptors to the cerebrum

c. hypothalamus: releases hormones; sets up daily rhythms

d. amygdala: relays sensory information to the cerebrum

e. olfactory bulbs: moderate motor centers in the cerebrum

Summary Introduction

Introduction:

The limbic system is present in the brain and consists of gray matter centers—thalamus, hypothalamus, basal nuclei, amygdala, hippocampus, and olfactory bulbs. These all have different functions but work in coordination to control the voluntary activities of body.

Explanation

Justification/explanation for the correct answer:

Option (c) is Hypothalamus: releases hormones; sets up daily rhythms. The hypothalamus control the basal metabolic rate of the body directly or by releasing hormones. Hence, option (c) is correct.

Explanation for the incorrect answer:

Option (a) is thalamus: relays the emotion signals through the limbic system. The main role of thalamus is to relay the sensory signals and motor signals to the cerebral cortex. So, it is an incorrect option.

Option (b) is basal nuclei: relays the inputs from the odor receptors to the cerebrum...
