Inferior view of the brain
After completing this study unit you will be able to:
- Describe the visible parts of the brain on the inferior view.
- Name and demarcate the 2 parts of the inferior surface of the cerebrum.
- Identify the main gyri and sulci seen on each part of the inferior surface of the cerebrum.
The inferior surface of the cerebrum is divided by a prominent groove called the lateral (Sylvian) sulcus into an anterior and a posterior part.
- The anterior part represents the orbital surface of the frontal lobe that lies on the floor of the anterior cranial fossa. The most important landmarks on the orbital part are the three orbital gyri, and the straight gyrus.
- The posterior part represents the basal aspects of the temporal and occipital lobes that lie on the floor of the middle cranial fossa and the upper surface of the tentorium cerebelli. The tentorial part is marked by the inferior temporal, inferior occipital and lingual gyri, and the fusiform gyrus.
Besides the cortical areas, there are some structures of the diencephalon and brainstem that are visible in this inferior view of the brain.
Watch the following video to find out more about all those structures and striking features of the brain seen on the inferior surface!
