GENERAL HISTOLOGY

Detailed explanation-1: -The white matter is divided into the dorsal (or posterior) column (or funiculus), lateral column and ventral (or anterior) column (Figure 3.8).

Detailed explanation-2: -White matter is found in the deeper tissues of the brain (subcortical). It contains nerve fibers (axons), which are extensions of nerve cells (neurons). Many of these nerve fibers are surrounded by a type of sheath or covering called myelin. Myelin gives the white matter its color.

Detailed explanation-3: -Similarly to the brain, the grey matter also splits into specific sections in the spinal cord. The three sections are the anterior grey column, the posterior grey column, and the lateral grey column.

Detailed explanation-4: -The largest white matter structure of the brain is the corpus collosum, a form of commissural tract that connects the right and left hemispheres.
