PATHOLOGY

Detailed explanation-1: -Grey matter consists of neuronal cell bodies and their dendrites. The dendrites are short protrusions (like little fingers) that communicate with neurons close by. In contrast, your white matter consists of the long axons of neurons that transmit impulses to more distant regions of your brain and spinal cord.

Detailed explanation-2: -The correct answer is (a): Gray matter consists of cell bodies, dendrites, and unmyelinated axons. White matter gets its color from myelin, which is a white membranous wrapping around axons. Hence, gray matter appears gray due to the lack of white myelin.

Detailed explanation-3: -Grey matter is made up of mostly somas and dendrites, where the integration and initiation of local information takes place, in other words information is processed and passed in close proximity to other neurons.

Detailed explanation-4: -White matter is the whitish nerve tissue of the central nervous system that is mainly composed of myelinated nerve fibers (or axons). The central nervous system is the brain and spinal cord. And gray matter is grayish nerve tissue of the central nervous system mainly composed of nerve cell bodies and dendrites.
