Definitions:

Gray Matter

The grayish neurons and neural segments that are involved in spinal reflexes.

Non-myelinated Neurons

Neurons without a myelin sheath, resulting in slower transmission of nerve impulses as compared to myelinated neurons.

Glial Cells

Cells that remove dead neurons and waste products from the nervous system, nourish and insulate neurons, form myelin, and play a role in neural transmission of messages.

Myelin

A fatty substance that encases and insulates axons, facilitating transmission of neural impulses.
