Anterior Funiculus

Thursday, October 29, 2009

The anterior funiculus is the bundle of white matter which lies on both sides of the spinal cord anterior median fissure and is bounded by the ventral roots of the spinal nerves. The anterior funiculus is composed of longitudinal motor fibers which come down from the cerebral cortex via the cerebral peduncles and the pyramid. Fibers from the anterior funiculus, along with axons from radial neurons in the anterior horn of the grey commisure, form the ventral roots of the spinal nerves.
