GENERAL HISTOLOGY

Detailed explanation-1: -parietal and occipital lobes; the transverse fissure, which divides the cerebrum from the cerebellum; and the longitudinal fissure, which divides the cerebrum into two hemispheres.

Detailed explanation-2: -The cerebral hemispheres are partially separate from each other along the midline by the interhemispheric fissure (deep groove) the falx cerebri (Figure 1.8A); Posteriorly, there is a transverse fissure that separates the cerebral hemisphere from the cerebellum, and contains the tentorium cerebellum.

Detailed explanation-3: -The longitudinal fissure (or cerebral fissure, great longitudinal fissure, median longitudinal fissure, interhemispheric fissure) is the deep groove that separates the two cerebral hemispheres of the vertebrate brain. Lying within it is a continuation of the dura mater (one of the meninges) called the falx cerebri.

Detailed explanation-4: -The cerebral hemispheres are paired structures separated from each other by the longitudinal fissure along the midline. A mid-sagittal cut through the longitudinal fissure is used to produce two hemisected brains. Each cerebral hemisphere is organized into five lobes: frontal, parietal, occipital, temporal and insula.

Detailed explanation-5: -The cerebellum is located in the posterior cranial fossa. The fourth ventricle, pons and medulla are in front of the cerebellum. It is separated from the overlying cerebrum by a layer of leathery dura mater, the tentorium cerebelli; all of its connections with other parts of the brain travel through the pons.
