The frontal lobe is considered as all cortex situated anterior to the central sulcus and superior to the Sylvian fissure, encompassing the frontal pole of brain. The frontal lobe is the largest lobe of the brain comprising almost one-third of the hemispheric surface.
What is the occipital lobe?
The occipital lobe refers to a region of cortex encompassing the posterior pole of the brain. The occipital lobe lies over the tentorium cerebelli while its medial surface faces the falx cerebri. There is no clear defined sulcus separating the occipital lobe from parietal and temporal lobes; however, it is separated from the other lobes by a theoretical line starting from parieto-occipital fissure and extending to temporo-occipital incisure.
What is the brain?
The brain is a complex organ with many layers and components that play their roles, in one way or another, in almost every function performed by the body. To complicate matters, an otherwise uniform-looking region can contain sub-regions responsible for performing vastly different functions.
Where is the central sulcus located?
The central sulcus is a longitudinal infolding that begins on the medial surface of the brain. It extends laterally over the superior surface of the brain and continues almost all the way down the lateral surface of the brain to the Sylvian fissure, the lateral cerebral sulcus.
What is the lateral boundary of the superior frontal gyrus?
The superior frontal sulcus is the lateral boundary of the superior frontal gyrus. This sulcus is a deep horizontal sulcus which can be recognized in coronal and horizontal sections. Many shallow sulci are present in the superior frontal gyrus.
Which artery supplies the frontal cortex?
The medial surface of the frontal cortex is supplied primarily by branches of the anterior cerebral artery; whereas parts of the lateral surface receive blood supply from branches of the medial cerebral artery.
