- - - - barorecetor: blood pressure
  - - - sclera: white part of the eye, dense connective tissue, anchor for extrinsic muscles, give eyeball shape
      - cornea: transparent, allows light in the eye, helps focus the light
    - - ciliary body: changes the shape of the lens
      - choroid: posterior part of the eye, nourishes other layers of the eye, absorbs light to prevent scattering
    - - deepest layer, contains our photo receptors, axons converge to form the optic nerve
  - - - photo receptors within the retina
    - - occipital lobe
  - - - olfactory bulb
      - cribreform plates
      - cribreform foramina
      - olfactory sensory neurons
    - - pseudostratified columnar epithelium
      - olfactory sensory neurons

        vestibular nerve
- - - - skin, body-wall, mainly everything except the ventral body cavity
    - - skin, skeletal muscle, joints, hearing, equilibrium
  - - - ventral body organs, taste, smell
    - - everything in the ventral body cavity, aretor pili, sweat glands
- - - - oligodendrocytes: creation of myelin sheath
      - schwann: creation of myelin sheath
