White Matter

Tissue in the brain and spinal cord composed of myelinated nerve fibers, responsible for transmitting signals within the nervous system.

Gray Matter

Nervous system tissue made up of neuron cell bodies, dendrites, and unmyelinated axons, found in the brain and spinal cord, crucial for processing information.

Columns

In anatomical terms, columns refer to structures shaped like pillars, often found in the spinal cord, which consist of white matter that carries nerve impulses to and from the brain.
