  1. The Nervous System Fetal Pig Dissection Part 6

  2. Hyperpolarization

  3. The Cranial Nerves (See Packet)

  4. The Brain

  5. Your Dissection:

  6. Brain Anatomy • Arbor Vitae: (Tree of Life) branched white matter within the cerebellum • Circle of Willis: arteries supplying blood to the base of the brain • Hypophysis: pituitary gland • Meninges, Dura Mater, Pia Mater, Arachnoid: membranes covering brain and spinal cord

  7. The Eye

  8. Backside view

  9. Your Dissection

  10. Eye Anatomy • Sclera: White, outer fibrous layer • Choroid: many blood vessels, absorbs stray rays of light • Ciliary muscle: controls the shape of the lens • Iris: regulates the size of the pupil • Vitreous Humor: jelly like fluid behind the lens

  11. Eye Anatomy • Aqueous Humor: watery fluid between cornea and lens • Retina: dark shiny layer
