1. Brain Architecture Jr / Sr Vet Science Mrs. Chotkowski Nervous System

2. OKAY……………..Let’s review Brain: Three basic units….. 1.Forebrain 2.Midbrain 3.Hindbrain

3. Hind Brain Includes: Upper part of brain stem Upper part of spinal cord Wrinkled ball of tissue called the: cerebellum (Tree of Life)

4. Hind Brain Controls: Bodily vital functions such as: respiration and heart rate

5. Hind Brain Cerebellum: Coordinates movement: Ball throwing, playing the piano

6. Mid Brain Controls some reflex actions: Eye movement and other voluntary movement.

7. Fore Brain The largest and most highly developed part of the human brain. Consists primarily of the cerebrum and the structures beneath it.

8. Fore Brain Cerebrum: The source of intellectual activities Is split into two halves Signals cross over when they go to the brain R L

9. Cerebrum Second largest part of the brain Coordinates muscle activity for smooth movement

10. Cerebrum

11. Cerebellum

12. Lobes of the Brain 1.Frontal Lobe: Organization, reason, short term storage

13. Lobes of the Brain 2.Parietal Lobes: Sensory Areas: Info @ taste, touch, and movement. (Reading and arithmetic)

14. Lobes of the Brain 3.Occipital Lobes: Process images from the eyes

15. Lobes of the Brain 4.Temporal Lobes: Appreciating music, receives info from the ears, integrating memory such as music, taste, sound, sight and touch.

16. Cerebral Cortex Gray matter, surface of the brain, the width of three dimes. Vital information processing takes place here.

17. Hypothalamus @ size of a pearl Adrenaline Emotions Secretes: Releasing and inhibiting factors that affect substance release from pituitary

18. Hypothalamus

19. Thalamus Clearinghouse for information going to and from the spinal cord

20. Thalamus

21. Meninges Connective tissue, encases the brain and spinal cord 3 layers Encloses the CNS 3 layers: Dura mater, Arachnoid and Pia mater Means durable Means spider Means soft and tender

22. Meninges

23. Olfactory Bulb Responsible for an animal’s sense of smell

24. Olfactory Bulb

25. Pituitary Gland Also called hypophysis Master gland: it secretes many hormones that control or master other endocrine glands

26. Pituitary Gland Acts in response to: Stimuli from the hypothalamus

27. Pituitary Gland

28. Medulla Oblongata Cranial end of the spinal cord Controls basic life functions

29. Medulla Oblongata

30. Spinal Cord Continuation of the medulla oblongata

31. Spinal Cord

32. Brain Stem Stalk-like, connects the cerebral hemisphere with the spinal cord: Consists of the: Pons, medulla oblongata, mid brain and interbrain

33. Brain Stem
