1. Parts/lobes of the brain
Bullet 1
MT: Nervous system 1

2. 4 Lobes of the Brain Frontal Parietal Temporal Occipital
Insula (hidden & controversial)

3. Frontal Lobe
Fxns: reasoning, planning, problem solving, logics, thinking
Biggest area of brain
Stops developing ~25 years old

4. Parietal Lobe
Fxns: recognizing stimuli, orientation, and recognition

5. Temporal Lobe
Fxns: memory, speech, and auditory stimuli

6. Occipital Lobe
Fxns: visual processing

7. Important Lines of Brain
Central Sulcus: separates frontal and parietal lobes

8. Important Lines of Brain
Lateral fissure: separates temporal and frontal lobes

9. Important Lines of Brain
Longitudinal fissure: separates brain medially

10. INSIDE OF Brain

11. Parts of the Brain
Brainstem (old reptilian brain) = midbrain, pons, and medulla oblongata
Limbic System (old mammalian brain) = thalamus, hypothalamus, amygdala, hippocampus
Corpus Callosum

12. Brainstem: Midbrain, Pons, Medulla Oblongata

13. Brainstem: Midbrain: -superior end of brainstem
-Fxn: eye mvmts, reflexes in pupil
Pons:
-inbetween midbrain and medulla
-Fxn: regulates respiration (breathing)
Medulla Oblongata:
-inferior end of brainstem; leads into spinal cord
-Fxn: heart rate, vomiting, coughing, sneezing, hiccupping, swallowing

14. Parts of the Brain
Brainstem (old reptilian brain) = midbrain, pons, and medulla oblongata
Limbic System (old mammalian brain) = thalamus, hypothalamus, amygdala, hippocampus
Corpus Callosum

15. Limbic System Thalamus:
-Fxn: relay center; most sensory neurons go here and then they are sent to correct place
Hypothalamus:
-Fxn: controls sleep/wake cycles, homeostasis, thirst, appetite
Hippocampus:
-Fxn: memory and learning
Amygdala:
-Fxn: memory of emotional situations especially fear

16. Limbic System

17. Parts of the Brain
Brainstem (old reptilian brain) = midbrain, pons, and medulla oblongata
Limbic System (old mammalian brain) = thalamus, hypothalamus, amygdala, hippocampus
Corpus Callosum

18. Corpus Callosum Corpus Callosum:
-Fxn: neurons cross to other side of brain
Ex: left eye sends signal through left hemisphere, through the corpus callosum, to the right hemisphere, to the occipital lobe

19. Corpus Callosum

20. Cranial Nerves 1-6 Cranial Nerve # Function CN I: Olfactory
Sense of smell
CN II: Optic
Vision
CN III: Oculomotor
Eye mvtmts, pupil regulation
CN IV: Trochlear
Eye movements
CN V: Trigeminal
Sense head and face, chewing
CN VI: Abducent
Abduction of eye

21. Cranial Nerves 7-12 CN VII: Facial
Function
CN VII: Facial
Facial expressions, saliva, tears, taste
CN VIII: Vestibulocochlear
Sense of balance, hearing
CN IX: Glossopharyngeal
Sense of tongue, swallowing, saliva, blood pressure control
CN X: Vagus
Movements of organs, slows heart, increases digestion, voice production
CN XI: Accessory
Movements of shoulders, head, and viscera (organs)
CN XII: Hypoglossal
Tongue movements

22. Facial (VII)
