Laboratory 11: Cartoons Chiyeko Tsuchitani, Ph.D. NOTE: These illustrations are NOT to be reproduced in the public domain For the visually challenged, cartoons that may help you remember some hypothalamic nuclei and limbic structures. You can study the figures and the review questions in Lab 11 of the Laboratory Guide to learn the connections and functions of these structures.. PS #26 For PS24: Two Cows 1. What is the cow at the left eating? 2. What is hanging off the chin of the cow at the left ? 3. What is forming the chin of the cow at the left? 4. What is hanging over the nose of the cow at the left? 5. What is forming the dark nose of the cow at the right? 6. What is forming the chin of the cow at the right? 7. What is forming the hollow “bump” on the forehead of the cow at the right? 8. Is the thalamus present in this picture? 9. Can you locate the supraoptic and suprachiasmatic nuclei? For PS24: Two Cows 1. The anterior commissure 2. The optic chiasm 3. The preoptic nucleus of the hypothalamus 4. The column of the fornix 5. The postcommissural fornix 6. The anterior nucleus of the hypothalamus 7. The terminal vein 8. The thalamus is not present in this picture. 9. The supraoptic nucleus is above the optic tract (right) and suprachiasmatic nucleus is above the optic chiasm. PS #25 For PS25: Armadillo 1. The nose of the armadillo is what structure? 2. What hypothalamic nucleus forms the snout (above the nose) ? 3. What forms the eyes of the armadillo ? 4. What forms the ears of the armadillo? 5. What nucleus is lateral to her ears? 6. Can you find the stria terminalis? 7. What does the stria terminalis connect? 8. Can you find the DM, VM, and arcuate hypothalamic nuclei? How about the lateral zone & medial forebrain bundle? For PS25: Armadillo 1. Infundibular stem/stalk 2. The arcuate nucleus 3. The postcommissural fornix 4. Anterior nucleus of the thalamus (A for Armadillo) 5. The Ventral Anterior (VA) nucleus of the thalamus 6. The stria terminalis is next to the terminal vein. 7. The stria terminalis connects the amygdala to the septal area and the hypothalamus. 8. Yes – see labeled slides on Neuroscience web site & DeArmond, Fig. 68, page 136. PS #24 For PS24: Dog 1. What forms the ears of the dog ? 2. What forms the eyes of the dog ? 3. What forms the nostrils of the dog ? 4. Can you locate the DM and VL thalamic nuclei ? 5. Can you find the stria terminalis? 6. What does the stria terminalis connect? 7. Can you find the DM, VM, and arcuate hypothalamic nuclei? How about the lateral zone & medial forebrain bundle? For PS24: Dog 1. Caudate body 2. The mammillothalamic tract 3. The postcommissural fornix 4. Yes, the thalamus DM is forms the medial part of his forehead & VL forms the lateral part, which extends towards his ears. 6. The stria terminalis is next to the terminal vein. 7. The stria terminalis connects the amygdala to the septal area and the hypothalamus. 8. Yes – see labeled slides on Neuroscience web site & DeArmond, Fig. 68, page 136. PS #22 For PS22: Lion Kings 1. What forms the muzzles of the lions ? 2. What outlines the muzzles ? 3. What forms the dark manes of the lions ? 4. Can you find the DM, VM, and arcuate hypothalamic nuclei? 5. Can you find the mammillary nuclei ? 6. Can you find the medial forebrain bundle? 7. Can you find the posterior hypothalamic nucleus ? 8. Can you find the mammillothalamic tract? 9. What does the mammillothalamic tract connect? For PS22: Lion Kings 1. The dorsomedial nucleus of the thalamus 2. The internal medullary lamina 3. The posterior limb of the internal capsule 4. No, this section is caudal to those nuclei. 5. The mammillary nuclei are the paws of the lion (near midline). 6. The medial forebrain bundle is lateral to the mammillary nucleus. 7. The posterior hypothalamic nucleus is superior to the mammillary nucleus. 8. The mammillothalamic tract lies on the superior-medial surface of the mammillary nucleus. 9. It connects the mammillary nucleus to the anterior thalamic nucleus..
