Presentation Transcript

  1. Nervous System

  2. Anatomical Divisions • CNS • Brain • Spinal Cord

  3. Anatomical Divisions • CNS • Brain • Spinal Cord • PNS • Spinal Nerves & Plexi

  4. Anatomical Divisions • CNS • Brain • Spinal Cord • PNS • Spinal Nerves & Plexi • Cranial Nerves • Peripheral Nerves

  5. Functional Divisions • Afferent • Efferent • Somatic • Autonomic • Sympathetic • Parasympathetic

  6. Principle Parts of the Brain • Cerebrum (Telencephalon)

  7. Principle Parts of the Brain • Cerebrum (Telencephalon) • Diencephalon

  8. Principle Parts of the Brain • Cerebrum (Telencephalon) • Diencephalon • Thalamus • Hypothalamus • Pineal Gland

  9. Principle Parts of the Brain • Brain Stem • Midbrain (Mesencephalon)

  10. Principle Parts of the Brain • Brain Stem • Midbrain (Mesencephalon) • Pons (Metencephalon)

  11. Principle Parts of the Brain • Brain Stem • Midbrain (Mesencephalon) • Pons (Metencephalon) • Medulla Oblongata (Myelencephalon)

  12. Principle Parts of the Brain • Brain Stem • Midbrain (Mesencephalon) • Pons (Metencephalon) • Medulla Oblongata (Myelencephalon) • Cerebellum

  13. Protection of the Brain • Skull

  14. Protection of the Brain • Skull • Meninges

  15. Protection of the Brain • Skull • Meninges • CSF

  16. Ventricles of the Brain • Lateral Ventricles

  17. Ventricles of the Brain • Lateral Ventricles • 3rd Ventricle

  18. Ventricles of the Brain • Lateral Ventricles • 3rd Ventricle

  19. Ventricles of the Brain • Lateral Ventricles • 3rd Ventricle • 4th Ventricle

  20. Ventricles of the Brain • Lateral Ventricles • 3rd Ventricle • 4th Ventricle • The cerebral aqueduct links the 3rd and 4th ventricles

  21. CSF Circulation

  22. If the cerebral aqueduct were blocked: CSF would build up in the lateral and 3rd ventricles CSF would not be able to reach the subarachnoid space Both Neither

  23. Correct! • If the cerebral aqueduct were blocked: CSF would build up in the lateral and 3rd ventricles CSF would not be able to reach the subarachnoid space Both Neither

  24. Normal

  25. Hydrocephalus
