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; WebNeurones involved in Motor or Autonomic Control. In the ventral horn, lamina VIII and IX contain longitudinal columns of motoneurones. Each column occupies its own position in the ventral horn and extends over several segments of spinal cord. Extensor motoneurones are arranged in columns nearer the midline of the ventral horn, and flexor ...
