Exercise 17: Gross Anatomy of the Brain and Cranial Nerves

  • Identify the prosencephalon, mesencephalon, and rhombencephalon in an embryonic brain diagram and the adult brain structures that originate from each functional region (lecture notes).
  • Identify the brain white and gray matter.
  • List and identify four lobes of the cerebrum.
  • Name and identify the three parts of the diencephalon.
  • Name and identify the three parts of the brain stem.
  • Identify the cerebellum.
  • Identify in a human brain model or diagram:
    • The right and left lateral ventricles, third ventricle, fourth ventricle, cerebral aqueduct, choroid plexus, cerebrum, right and left cerebral hemispheres, the four cerebral lobes (frontal, parietal, temporal, occipital), gyrus, sulcus, longitudinal fissure, transverse fissure, corpus callosum, septum pellucidum, fornix, hypothalamus, thalamus, mammillary body, optic chiasma, pituitary gland, pineal gland, midbrain including anterior midbrain and posterior midbrain - corpora quadrigemina (superior and inferior colliculi), pons, cerebellum, arbor vitae, medulla oblongata, spinal cord, and central canal.
  • Identify in the sheep brain dissection:
    • Pia mater, right and left lateral ventricles, third ventricle, fourth ventricle, cerebral aqueduct, choroid plexus, cerebrum, right and left cerebral hemispheres, the four cerebral lobes, gyrus, sulcus, longitudinal fissure, transverse fissure, corpus callosum, fornix, hypothalamus, thalamus, optic chiasma, pituitary gland (if present), pineal gland, anterior midbrain, superior and inferior colliculi, pons, cerebellum, arbor vitae, medulla oblongata, spinal cord, and central canal.
  • State the function(s) for all parts studied.
  • List and identify the three meninges from superficial to deep and the spaces in between them.
  • Identify the four ventricles of the brain.
  • State the functions of cerebrospinal fluid.
  • Explain the CSF production, circulation, and reabsorption.
