- Placed in front of or in the anterior portion of the occipital lobe of the brain: as, the preoccipital fovea (a slight depression demarcating, in part, the occipital from the temporal lobe).
Sorry, no etymologies found.
Below, it is separated from the temporal lobe by the posterior ramus of the lateral fissure, and by a line carried backward from it to meet the line passing downward to the preoccipital notch.
The tentorial surface of the occipital lobe is limited in front by an imaginary transverse line through the preoccipital notch, and consists of the posterior part of the fusiform gyrus (occipitotemporal convolution) and the lower part of the lingual gyrus, which are separated from each other by the posterior segment of the collateral fissure.
Posteriorly, it is limited by the parietoöccipital fissure, and by a line carried across the hemisphere from the end of this fissure toward the preoccipital notch.
About 5 cm. in front of the occipital pole on the infero-lateral border is an indentation or notch, named the preoccipital notch.
The lateral surface is limited in front by the lateral part of the parietoöccipital fissure, and by a line carried from the end of this fissure to the preoccipital notch; it is traversed by the transverse occipital and the lateral occipital sulci.
