Define gray matter in the spinal cord. It is neural tissue that is dominated by the cell bodies of neurons, neuroglia, and unmyelinated axons, and surrounds the narrow central canal. It is neural tissue that contains large numbers of myelinated and unmyelinated axons. It contains the axons of motor neurons that extend into the periphery. It is neural tissue that contains the cell bodies of sensory neurons whose axons carry information to the spinal cord.

Explanation : Gray matter, named for its pinkish-gray color, is home to neural cell bodies, axon terminals, and dendrites, as well as all nerve synapses. This brain tissue is abundant in the cerebellum, cerebrum, and brain stem. It also forms a butterfly-shaped portion of the central spinal cord.

The back portion of this butterfly shape is known as the posterior, sometimes called the dorsal gray horn. This region passes sensory information via ascending nerve signals to the brain. The front part, which is sometimes called the ventral gray horn, sends descending nerve signals governing motor activities to your autonomic nerves. A problem with the dorsal gray horn may affect your brain's ability to interpret sensory information, while issues with the ventral gray horn interfere with your body's ability to receive motor information; paralysis, tingling, and muscle weakness are often the products of damage to the ventral gray horn.
