    • 1: Coronal Plane 
    • 2: Sagittal Plane 
    • 3: Axial Plane
  3. What plane is this?
    Image Upload 3
    Axial
  4. What plane is this?

    Image Upload 4
    Sagittal
  5. What plane is this?
    Image Upload 5
    Coronal
  6. What constitutes the main nervous system?
    Brain and spinal cord (encased by bone)
  7. What constitutes the peripheral nervous system?
    • Cranial nerves 
    • Spinal nerves 
    • Peripheral ganglia
    • This is encased by a vertebral column
  8. What are the 6 main subdivisions of the CNS?
    • 1: Spinal cord 
    • 2: Medulla 
    • 3: Pons and cerebellum 
    • 4: Midbrain 
    • 5: Diencephalon (made up of the thalamus and hypothalamus)
    • 6: Cerebral hemispheres
  9. On which basis is the brain divided?
    • Gross appearance:  e.g., gray matter vs white matter
    • Landmarks, e.g., sulci
    • Histology (cell anatomy)
    • Cytoarchitecture (cell composition)
    • Chemoarchitecture (distribution of neurotransmitters)
    • Projection patterns
    • Functional considerations
  10. Label this (I fucked the numbers up, add 1 to every number)

    • 3: Choroid plexus 
    • 4: Massa Intermedia 
    • 5: Corpus Callosum
    • 6: Thalmus
    • 7: Midbrain
    • 8: Tentorium
    • 9: Fourth ventricle
    • 10: Pons
    • 11: Cerebellum
    • 12: Choroid Plexus 
    • 13: Medulla 
    • 14: Spinal Cord
    • 15: Pituitary Gland
    • 16: Third Ventricle 
    • 17: Layers of Meninges 
    • 18: Cingulate Gyrus
  11. Label this

    • 1: Dorsal root ganglion
    • 2: Dorsal root
    • 3: Afferent axon
    • 4: To brain 
    • 5: Dura Mater
    • 6: Arachnoid Membrane
    • 7: Pia Mater
    • 8: Spinal nerve
    • 9: Vertebra 
    • 10: Fat tissue
    • 11: Subarachnoid space
    • 12: Spinal cord
    • 13: Motor neuron
    • 14: Efferent axon
    • 15: Ventral root
  12. What is a white matter tract?
    White matter with a common destination or origin
  13. What is a white matter Fasciculus, funiculus, peduncle or brachium?
    A distinct collection of nerve fibers (may contain many tracts)
  14. What is a white matter lemiscus?
    Ascending fibres in the brainstem
  15. How much cerebrospinal fluid can be found in an average adult human?
    125 ml
  16. Where is cerebrospinal fluid produced?
    Choroid plexus (mainly in the lateral ventricles)
  17. What is hydrocephalus?
    • There is an obstruction in the flow of cerebrospinal fluid 
    • This increases pressure within the brain, and can lead to damage
  18. What are the meninges?
    • Three membranous envelopes: pia mater, arachnoid and dura mater 
    • Cover the brain and spinal cord to offer protection to the CNS
  19. What is this the distribution of?
    Image Upload 8
    Noradrenaline
  20. What is this the distribution of?
    Image Upload 9
    Dopamine
  21. What is this the distribution of?
    Image Upload 10
    Acetylcholine
  22. What is this the distribution of?
    Image Upload 11
    Serotonin
