Question

diencephalon
the diencephalon, or interbrain, sits atop the brain stem and is enclosed by the cerebral hemispheres (see figure 7 12). the major structures of the ( 1 ) are the thalamus, hypothalamus, and epithalamus (figure 7 16). the thalamus, which encloses the shallow third ventricle of the brain, is a relay station for sensory impulses passing upward to the sensory cortex. as impulses surge through the ( 2 ), we have a crude recognition of whether the sensation we are about to have is pleasant or unpleasant. it is the neurons of the sensory cortex that actually localize and interpret the sensation.
the hypothalamus (literally, “under the thalamus”) makes up the floor of the diencephalon. it is an important ( 3 ) center because it plays a role in regulating body temperature, water balance, and metabolism. the hypothalamus is also the center for many drives and emotions, and as such it is an important part of the so - called limbic system, or “emotional - visceral brain.” for example, thirst, appetite, sex, pain, and pleasure centers are in the hypothalamus. additionally, the ( 4 ) regulates the pituitary gland (an endocrine organ) and produces two hormones of its own. the pituitary gland hangs from the anterior floor of the hypothalamus by a slender stalk. (we discuss its function in chapter 9.) the mammillary bodies, reflex centers involved in olfaction (the sense of smell), bulge from the floor of the hypothalamus posterior to the ( 5 ) gland

o 1 pituitary 2 diencephalon 3 thalamus 4 autonomic 5 hypothalamus

o 1 thalamus 2 autonomic 3 hypothalamus 4 pituitary 5 diencephalon

Explanation:

The diencephalon contains the thalamus, hypothalamus, and epithalamus. The thalamus is a sensory - impulse relay. As impulses pass through it, we have a crude sensation recognition. The hypothalamus is an important autonomic center regulating body functions and is part of the limbic system. It also regulates the pituitary gland. The mammillary bodies are related to olfaction and are posterior to the pituitary gland.
