Abstract:
Edification of neocortex is accompanied by the development and growth of the cerebral hemisphere, both processes being part of the more complex one, known under the name of telencephalization. The expression of this process is more acute on the superolateral surface of the cerebral hemisphere that expands laterally by growth of the frontal, temporal and parietal lobes. We describe the modifications of shape and deepness of the lateral cerebral fossa including the stages of its closure. We consider this event as the beginning of the appearance of gyri and sulci on the superolateral surface of the cerebral hemisphere.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Cerebellar Structure
Externally, the cerebellum features a highly convoluted surface with numerous folia (narrow ridges) separated by shallow sulci (grooves). The cerebellum is divided into two hemispheres by a thin median structure known as the vermis. The...
