    1. CENTRAL NERVOUS SYSTEM Dissection of the Sheep Brain Including Midsagittal, Dorsal and Ventral Sections

    2. Midsagittal Section: Cerebrum and Cerebellum Cerebrum consists of two hemispheres, each with 4 lobes: frontal, parietal, occipital, and temporal (lateral view) corpus callosum -commissural fibers joining right and left hemispheres fornix - connects ??? Cerebellum - consists of folia (folds) of gray matter arbor vitae - white tracts in cerebellum Ventricles - filled with cerebrospinal fluid (CSF) lateral - within cerebral hemispheres fourth - between cerebellum and pons Cerebrum consists of two hemispheres, each with 4 lobes: frontal, parietal, occipital, and temporal (lateral view) corpus callosum -commissural fibers joining right and left hemispheres fornix - connects ??? Cerebellum - consists of folia (folds) of gray matter arbor vitae - white tracts in cerebellum Ventricles - filled with cerebrospinal fluid (CSF) lateral - within cerebral hemispheres fourth - between cerebellum and pons

    3. Midsagittal Section: Diencephalon - Thalamus & Epithalamus Diencephalon consists of epithalamus (pineal body and choroid plexuses of 3rd ventricle), thalamusDiencephalon consists of epithalamus (pineal body and choroid plexuses of 3rd ventricle), thalamus

    4. Midsagittal Section: Diencephalon - Hypothalamus

    5. Midsagittal Section: Brain Stem

    6. Midsagittal Section: Cerebellum and Spinal Cord

    7. Dorsal View – Whole Brain Sulci (sing. sulcus) – grooves between ridges Gyri (sing. gyrus) – ridgesSulci (sing. sulcus) – grooves between ridges Gyri (sing. gyrus) – ridges
