NOTE: DO NOT ATTEMPT ANY OF THESE LABS UNTIL AFTER YOU HAVE GONE THROUGH ALL OF THE LECTURE TOPICS MATERIAL! IT PROVIDES THE NECESSARY BACKGROUND INFORMATION. YOU DO NOT NEED TO GET ANY CHECK OFFS FROM THE LAB STAFF FOR ANY OF THESE LAB EXERCISES, BUT YOU WILL NEED THIS INFORMATION FOR YOUR ONLINE LAB SELF-QUIZ (LQ-10). YOU WILL NEED YOUR TEXTBOOK. YOU MAY ALSO NEED TO REFER TO YOUR LECTURE NOTES TO ANSWER SOME OF THE QUESTIONS. STEP 2, Part A: Spinal Cord Model Find the Spinal Cord Model in the A&P area, and answer Questions #1-18 (below). DO NOT take the model to your desk. You must use it on the counter. The model closely resembles figure 12.31 in your textbook. For Questions #1-18, ONLY use the following terms (word for word and spelled correctly) to fill in each blank: central canal, gray commissure, dorsal horn, ventral horn, lateral horn, dorsal root ganglion, dorsal root, ventral root, posterior funiculus, anterior funiculus, lateral funiculus, spinal nerve, unless you are given the choice of two different terms in parentheses. 1. ________________________________ What is structure 5 on the model? 2. ________________________________ What is structure 6 on the model? 3. ________________________________ What is structure 7 on the model? 4. ________________________________ The structures 5, 6, and 7 are made of (gray / white) matter. Choose one answer or the other. 5. ___________________________________ What is structure 1 on the model? 6. ___________________________________ What is structure 2 on the model? 7. ___________________________________ What is structure 3 on the model? 8. ___________________________________ The structures 1, 2, and 3 are made of (gray / white) matter. Choose one answer or the other. 9. ___________________________________ What is the hole labeled 9 on the model? 10. __________________________________ What is the structure labeled 8 on the model?

11. __________________________________ What is the structure labeled 23 on the model? 12. __________________________________ What is the structure labeled 24 on the model? 13. __________________________________ What is the structure labeled 25 on the model? 14. __________________________________ What is the structure labeled 26 on the model? 15. __________________________________ The red and black wires on the model stand for what types of neurons (sensory or motor)? Hint: look at the at the diagram at the bottom of the model and note the locations of the neuron cell bodies; also see fig. 12.32 in textbook. 16. __________________________________ The neuron cell bodies for the neurons represented by the red and black wires are located in the _______ ? (CNS or PNS) 17. __________________________________ The green and yellow wires on the model stand for what types of neurons (sensory or motor)? Hint: look at the at the diagram at the bottom of the model and note the locations of the neuron cell bodies; also see fig. 12.32 in textbook. 18. __________________________________ The neuron cell bodies for the neurons represented by the green and yellow wires are located in the _______ ? (CNS or PNS) _____________________________________________________________________________ _ STEP 2, Part B: Brain Model Find the Brain Model in the A&P area, and answer Questions #19-44 (below). Be sure that you are looking at the correct model. The model that you need to use has a lot more numbers than the other model on the counter, which is for the BIO 160 students. DO NOT take the model to your desk. You must use it on the counter. The model closely resembles figures 12.6 and 12.12 in your textbook. For Questions #19-44, ONLY use the following terms (word for word and spelled correctly) to fill in each blank. I have listed more terms than you will need to use: frontal lobe, occipital lobe, parietal lobe, temporal lobe, postcentral gyrus, precentral gyrus, central sulcus, midbrain, pons, medulla oblongata, pineal gland, fornix, cerebellum, corpus callosum, cerebral aqueduct, septum pellucidum, optic chiasma, mammillary body, arbor vitae, thalamus, fourth ventricle, pituitary gland, hypothalamus, olfactory bulb, insula, unless you are given the choice of two or more different terms in parentheses. WHOLE BRAIN (fig. 12.6) ________________________________ 19. Which gyrus is indicated by the 15 on the model? 20. ________________________________ Which gyrus is indicated by the 4 on the model?

21. ________________________________ What structure (depression) is located in between structures 4 and 15 on the model? 22. ________________________________ Name the lobe indictated by 11 on the model? 23. ________________________________ What is the major function of the lobe indicated by 11? (motor, sensory, visual, or auditory) 24. ________________________________ Name the lobe indictated by 23 on the model? 25. ________________________________ What is the major function of the lobe indicated by 23? (motor, sensory, visual, or auditory) 26. ________________________________ Name the lobe indictated by 10 on the model? 27. ________________________________ What is the major function of the lobe indicated by 10? (motor, sensory, visual, or auditory) 28. ________________________________ Name the lobe indictated by 22 on the model? 29. ________________________________ What is the major function of the lobe indicated by 22? (motor, sensory, visual, or auditory) 30. ________________________________ What lobe of the brain is not shown on the model? Hint: it is the internal one. 31. ________________________________ What is the structure labeled I in the inferior view of the brain? (you will need to look at fig. 12.14 for this one) MIDSAGITTAL BRAIN (fig. 12.12) 32. __________________________________ What is the entire structure labeled 79 on the model? 33. __________________________________ What is the internal white area of the structure labeled 79 on the model? 34. __________________________________ What is the structure labeled 52 on the model? 35. __________________________________ What is the structure labeled 54 on the model? 36. __________________________________ What is the structure labeled 41 on the model? (Note: I am not looking for corpora quadrigemina or cerebral aqeduct. These two structures together make up the term that I am looking for)
