Where is corpus callosum

The rostrum is continuous with lamina terminals and connects the orbital surfaces of frontal lobes. It has a resemblance to a bird's beak; that why it's called rostrum. The genu is an outgrowth of the anterior corpus callosum. The long central section is called the body, and its fibers extend to the surface of the hemispheres through the corona radiate. Forceps major project fibers from the splenium and connects the occipital lobes.

This tact tapers away at the posterior section. A narrowed part between splenium and trunk is known as the isthmus. The corpus callosum always needs a constant and abundant blood supply to perform its functions. Infarcts uncommonly involve it. Mostly it gets its blood supply via pericallosal, the posterior pericallosal arteries, and branches from the anterior and posterior cerebral.

Besides, if it needs extra blood, then it receives blood from the anterior communicating artery via a median callosal artery or the subcallosal artery. How different fibers of corpus callosum get blood supply is described below. Have a look to know more about the histology of corpus callosum. The primary purpose of the corpus callosum is to integrate the information by joining both cerebral hemispheres to process motor, sensory, and cognitive signals.

It connects the similar areas of the brain and transmits the information across the left and right hemispheres. For instance, rostrum and genu connect the frontal horns of right and left hemispheres while body and splenium connect the temporal and occipital lobes of both hemispheres. Similarly, by connected similar areas brings harmonization of their functions. Besides, corpus callosum plays a crucial role in eye movement and vision by connecting both halves of the hemispheres of the visual field.

This white matter nerve bundle allows us to identify and see the objects by connecting the visual cortex in brain language centers.

Additionally, Corpus callosum process the tactile information in the parietal lobes and transmit between the brain hemispheres to identify the touch.

Likewise, it helps in maintaining the balance of attention, arousal, and play a primary role in cognition. The study suggests that the weak integrity of corpus callosum causes a decline in cognitive function in adults. On the flip side, an increase in callosum thickness helps in those brain areas development , which correlates with intelligence, problem-solving activities, and processing speed.

Corpus Callosum is a significant part of the brain and integrates and transmits information between the left and right hemispheres.
