GENERAL HISTOLOGY

Detailed explanation-1: -The corpus callosum is the largest set of commissural fibers in the brain and is a pathway of crucial importance to speech-language functions (Fig. 2-10, B). The corpus callosum serves as the major connection between the hemispheres and conveys neural information from one hemisphere to the other.

Detailed explanation-2: -The corpus callosum is a collection of nerve fibers that connect the two hemispheres. The corpus callosum is divided into rostrum (head), body, the most rostrally part is the genu (knee) with connecting the rostrum and the body, and the splenium at the caudal extremity (Figure 1.10).

Detailed explanation-3: -White Matter 1. The white matter is deep to the cortex and consists of myelinated axons running in three principal directions. 2. Association fibers connect and transmit nerve impulses between gyri in the same hemisphere.

Detailed explanation-4: -Commissural tracts connect corresponding cortical areas in the two hemispheres. They cross from one cerebral hemisphere to the other through bridges called commissures. The great majority of commissural tracts pass through the largest commissure the corpus callosum.

Detailed explanation-5: -Corpus Callosum It connects the left and right cerebral hemispheres and facilitates interhemispheric communication.
