  • Wernicke = speech interpretation
  • Anatomy unit 2 nervous system the brain notes

    1. 1. ANATOMY Unit 2 Notes: The Brain
    2. 2. (1) Frontal Lobe • Speech Production (from Broca’s Area) • Concentration, Problem Solving, Planning • Voluntary Muscle Contractions
    3. 3. (2) Parietal Lobe • Interpretation of speech, sounds, surroundings • Pick up on skin sensations
    4. 4. (3) Temporal Lobe • Interpret sensations • Visual & Auditory Memory • Basic Hearing function • Ability to learn + connect concepts • Includes: – Thalamus – Hypothalamus – Pituitary Gland – Corpus Callosum – Limbic System
    5. 5. (4) Stuff In Your Temporal • Thalamus = Sensory reception • Hypothalamus = Control Body Temperature, Maintain fluid + ion levels, Regulates Metabolism, Sleep • Limbic System = Emotions • Pituitary = Regulate hormone secretion • Corpus Callosum = Connective tissue between left and right hemispheres
    6. 6. (5) Occipital Lobe • Vision • Combines images to make complete picture
    7. 7. (6) Cerebellum • Coordinates muscle movement • Maintains normal muscle tone • DOES NOT MAKE MUSCLES MOVE! – Makes them move smoothly!
    8. 8. (7) Brain Stem • Passes info between spinal cord + brain • Includes: – Midbrain – Pons – Medulla Oblongata
    9. 9. (8) Stuff in Brain Stem • Midbrain: – Fight or Flight responses (based of past) – Helps with vision + auditory senses • Pons: – Respiratory Reflexes – General Breathing Rate • Medulla Oblongata: – Maintains Homeostasis – Heartbeat, Blood pressure, Digestive reflexes – Also assists pons in respiration
