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
