1. Lateral
    Toward the sides
  2. Superior inferior
    above below
  3. proximal
    areas close in proximity
  4. distal
    locations that are farther in distance
  5. coronal slice
    divides front and back halves of brain
  6. horizontal slice
    separates top and bottom of the brain
  7. cross secretions
    horizontal slices in the spinal cord
  8. midsagittal cut
    cuts the brain between the eyes into equal left and right halves
  9. sagittal slices
    gradually more lateral cuts from the midline
  10. ipsilateral
    when two brain structures are located on the same side of the midline
  11. contralateral
    when two brain structures are located on opposite sudes of the midline
  12. meninges
    series of three membranes that protect the spinal cord and brain
  13. dura mater
    the outmost layer of the meninges, it is tough
  14. arachnoid layer
    the 2nd most outer layer of meninges, below the dura mater, spider web-like appearance
  15. pia mater
    the inner most meninges layer, very thin and adheres tightly to every contour of the brain and spinal cord
  16. subarachnoid
  17. subarachnoid
  18. subarachnoid space
    the space between the arachnoid layer and pia mater, it is filled with cerebrospinal fluid
  19. Anatomical directions
    • Anterior- front
    • Posterior- back
    • Dorsal- bottom
    • Ventral-top
  20. Ventricles
    system of hollow interconnected chambers in the brain.
  21. Central canal
    a long narrow channle that spans the center of the spinal cord.
  22. Choronoid plexus
    specialized capillary tissues that line each of the ventricles, create cerebrospinal fluid that flows to each ventricle
  23. lateral ventricles
    two large wing shaped ventricles, that serve the core of the cerebral hemispheres
  24. third ventricle
    this bisects the two lobes of the thalamus, at the center of the brain
  25. fourth ventricle
    located posterior to pons and meudlla, it is connected to the third ventricle by cerebral aqueduct
  26. cerebral aqueduct
    a very narrow channel that connects the third and fourth ventricles
  27. cerebrospinal fluid ( CSF)
    a colorless fluid that circulates through the subarachnoid space back to the top of the head. CSF helps keep you head weight balances, provides head with shock-absorbing cushion, provied nutrients to and removes wastes from the CNS
