WebDec 5, 2024 · The gray matter of the spinal cord is a butterfly-shaped structure made up of neuronal cell bodies, glial cells and neuropile (unmyelinated axons, dendrites and glial cell processes). The gray matter can be functionally divided into three main regions: The anterior horn is responsible for motor function; WebUsually, a group of neuronal cell bodies lying outside the central nervous system (CNS). Nerves A bundle of axons and/or dendrites covered with connective tissue found outside the central nervous system.
