Presentation Transcript

  1. Chapter 3 All About Biology

  2. The Basics • Nervous System: • The Central Nervous System • Brain and spinal cord • Peripheral Nervous System • Everything else

  3. Nervous System Breakdown

  4. Sympathetic vs. Almost Sympathetic Sympathetic Parasympathetic Rest and Digest Calms Relaxes • Fight or Flight • Anxiety • Increased respiration and blood flow to muscles related to movement

  5. Cell Structure Glial Cells Neurons Cell Body Dendrites Axon Myelin Sheath Synapse

  6. And Action!!! Or not...... • Action Potential vs. Resting Potential • All-or-nothing • Threshold • Concentration Gradient- Sodium vs. Potassium • PARABLE OF THE GREEK HOUSE TOILET

  7. “Can You Hear Me Now?” • Chemical message transmission- neurotransmitters • Acetylcholine (ACh) • Gamma aminobutryric acid (GABA) • Glutamate • Norepinephrine • Dopamine • Serotonin • Endorphins • Oxytocin

  8. Game Time!!!!!

  9. Instructions • Split into two teams. • Match the items you have been given to their correct counterparts. • Team that matches all items correctly wins!!!

  10. What does it look like? • Electroencephalograph (EEG) • Computerized Axial Tomography (CAT) • Positron-Emission Tomography (PET) • Magnetic Resonance Imaging (MRI) • Functional MRI (fMRI)

  11. Anatomy of the Brain • Hindbrain • Brainstem • Midbrain- Reticular Formation • Forebrain

  12. Anatomy (continued) • Limbic System: • Amygdala • Hippocampus • Thalamus • Hypothalamus • Cerebral Cortex

  13. Lobes of the Brain • Occipital • Temporal • Parietal • Frontal • Phineas Gage

  14. The Cortex • Motor Cortex • Somatosensory Cortex • Association Cortex • Broca’s Area • Wernicke’s Area

  15. Hemispheres • Split-Brain • Corpus Callosum • Integration • Plasticity

  16. Genetics • Selective Breeding- Mendel’s pea plants • Genotype vs. Phenotype

  17. Okay, girlie, I would love for you to put some great graphics in this one. If you can find some better than the few I have, you are welcome to change those too. • I really would like the picture of a cell with all its parts on the one slide where there is space provided. And I would love a fancy toilet on the action potential slide. But some cool graphics for action potentials would work too. • Thank you, thank you, thank you!!!!
