Chapter 33, Problem 11RQ
Summary Introduction
To name: The main functions linked with the brain structures – cerebrum, hypothalamus, thalamus, tectum, cerebellum, medulla oblongata, and limbic system.
Introduction: There are three principal divisions in the brains of early vertebrates, namely forebrain, midbrain and hindbrain. Each of these divisions is linked with one or more special senses. The forebrain is associated with smell, the hindbrain is associated with hearing and equilibrium and midbrain is associated with vision.

Name major functions associated with the following brain struc-tures: medulla oblongata, cerebellum, tectum, thalamus, hypothala-mus, cerebrum, limbic system.
Describe structure and provide a generalized function for each of the following regions of the brain: brain stem, diencephalon, cerebrum, cerebellum.
The limbic system is composed of several interconnected structures including the olfactory bulbs, amygdala, hypothalamus, hippocampus, parahippocampal gyrus, cingulate gyrus, subcallosal gyrus, septal nuclei, mammillary bodies, and the thalamus. Pair each of these structures with their function listed below:
-This limbic area is active when you are trying to memorize the names of brain areas. It is also severely atrophied in people suffering from late stages of Alzheimer’s Disease.
-This limbic area is active when you are watching something that makes you feel sad.
-This limbic area is active when you feel thirsty.
-When the activity of this limbic area is increased you feel a sense of pleasure.
-When this limbic area is damaged it often results in patients experiencing anterograde amnesia.
-Damage to this limbic structure while rare often results in patients going into a coma.
-This cortical limbic structure plays a large role in motivation and movement and has recently been…
