  27. CRANIAL NERVES

  28. I - Olfactory • II - Optic • III - Oculomotor • IV - Trochlear • V - Trigeminal • VI - Abducens • VII - Facial • VIII - Auditory • IX - Glossopharyngeal • X - Vagus • XI - Accessory • XII - Hypoglassal

  29. I. Olfactory: Sensory nerves for smell

  30. II. Optic: Sensory nerve for vision.

  31. III. Oculomotor:  control of extrinsic eye muscles and pupil dilation.

  32. IV. Trochlear: control of muscles that surround the eye

  33. V. Trigeminal: control of facial nerves and muscles for chewing.

  34. VI. Abducens: muscle control of lateral movement of the eyeball

  35. VII. Facial: control over facial expression and taste

  36. VIII. Vestibulocochlear or Auditory Nerve: Sensory nerve for hearing

  37. BRAIN IS SURROUNDED AND PROTECTED BYMENINGES

  38. MENINGES • DURA MATTER – TOUGHEST, BETWEEN IT ARE MENINGEAL ARTERIES AND DURAL SINUSES. • ARACHNOID – DELICATE TRANSPARENT, SEPARATED FROM DURA M. BY SUBDURAL SPACE. • PIA MATTER – HIGHLY VASCULAR, ADHERES TO THE CONTOURS OF BRAIN. SUBARACHNOID SPACE SEPARATES PIA M. FROM ARACHNOID S.

  39. DURAL FOLDS • FALX CEREBRI – SEPARATES TWO HEMISPHERES • TENTROIUM CEREBELLI - SEPARATES THE CEREBRUM AND CEREBELLUM

  40. F.C.

  41. TEN

  42. VENTRICLES • PATHWAY FOR CIRCULATION OF CSF

  43. VENTRICLES COMMUNICATION • LATERAL VENTRICLES - L & R- SEPTUM PELLUCIDUM • LATERAL AND III – FORAMEN OF MONROE • III AND IV – AQUEDUCT OF SYLVIUS

  44. LATERAL VENTRICLES L.V.

  46. L.V. III V. L.V. O. HORN CHOROID PLEXUS

  47. L.V. S.F. III.V. L.V.

  48. CEREBRUM • CONSISTS OF W. MATTER AND G. MATTER. • C. CORTEX – OUTERMOST PORTION OF CEREBRUM. • CORPUS COLLOSUM – WHITE MATTER BUNDLE CONNECTS R & L CEREBRAL HEMISPHERES.

  49. BASAL GANGLIA • CAUDATE NUCLEUS • LENTIFORM NUCLEUS • CLAUSTRUM • THALAMUS
