Brain

Lab Summary

In this lab the structures of the brain are taught. Included in this guide is detailed description of base of brain along with its vascularity, lateral view of the hemispheres and posterior fossa structures and a midline dissection of brain describing the midline hemispheres, diencephalon and venous sinuses.

Lab Objectives

Identify the lobes of the brain.
Identify the midbrain, pons, medulla and cerebellum.
Locate the cranial nerves on the base of the brain.
Describe the circle of Willis.
Describe the flow cerebrospinal fluid (CSF).
Describe position of dural folds.
Describe dural venous sinuses.
