Terms: forebrain, midbrain, hindbrain, telencephalon, diencephalon, mesencephalon, metencephalon, myelencephalon.

2. Identify the location and function of the following structures associated with the brain: lateral ventricles, third ventricle, fourth ventricle, lateral and medial apertures, interventricular foramen (foramen of Monro), septum pellucidum, cerebral aqueduct, meninges, falx cerebri, falx cerebelli, tentorium, cerebrospinal fluid.

3. Describe the role and general pathway and cycling of the cerebrospinal fluid of the brain and spinal cord. Terms: choroid plexus, arachnoid villi (granulations).

4. Identify the locations and functions of the following structures associated with the cerebral hemispheres: gyri, sulci, fissures, longitudinal fissure, transverse fissure, central sulcus, parieto-occipital sulcus, post-central gyrus, pre-central gyrus, frontal lobe, parietal lobe, temporal lobe, occipital lobe, insula, cerebral cortex.
