11. Time’s up! Put Bell Ringer in Folder Today’s Agenda: Quick review Practice quiz

12. Basal Ganglia Controlmuscularmovements – WhereParkinson’sDiseaseoriginates

13. Limbic System Functions and components of limbic system: – Hippocampus = long-term memories – Amygdala = behavior, emotions – Hypothalamus & Thalamus – Processes smell

14. Thalamus “Relay station” for sensory input before going to the cerebral cortex (lobes)

15. Hypothalamus (size of an almond) Regulates temperature, hunger/thirst, water balance (urination)

16. Pons Controls breathing, facial expressions, & dreams

17. Medulla Oblongata breathing, heart rate, blood pressure, swallowing and vomiting.

18. The Fibrous Tunic Cornea – Clear – Only human tissue that can be transplanted without fear of rejection

20. Retina - responds to light and transmits visual signal to brain – Contains rods and cones Rods – Process black and white images Cones – Processes color images

21. The Ear Two functions – Hearing – Equilibrium (balance)

22. The External Ear Involved in hearing only Structures of the external ear – Pinna – auditory canal Wax glands are present Figure 8.12

23. Middle Ear Figure 8.12 Eardrum Three bones: – Hammer – Anvil – Stirrip

24. Inner Ear Cochlea – – Contain fluid and hair cells – Once you damage these hair cells, they will never grow back. What causes damage? LOUD MUSIC!!!! Figure 8.12

25. Olfaction – The Sense of Smell Olfactory receptors are in the roof of the nasal cavity – Neurons with long cilia Interpretation of smells is made in the limbic system – part of your brain dealing with memory & emotion – this is why some smells remind us of certain memories and feelings

26. Gustation = The Sense of Taste Taste buds house the receptor organs Location of taste buds – Most are on the tongue – Soft palate – Cheeks Figure 8.18a–b

27. Human Anatomy, Frolich, Head II: Throat/Larynx Five taste sensations Sweet Sour Salty Bitter “umami” (savory) M&M, Fig. 16.1

28. Practice Quiz Try it on your own to get an idea of how you will do on tomorrows quiz

29. Answers: 1.C – Limbic System 2.A – Basal Ganglia 3.B – Pons 4.A – Thalamus 5.D – Both b&c 6.C - They would get smaller because they do not need to absorb more light 7.B – Occipital Lobe 8.C – Limbic System 9.C – Equilibrium 10. Smell
