White ramus communicans
Introduction
Template:Infobox Anatomy The thoracic, and the first and second lumbar nerves each contribute a branch, white ramus communicans to the adjoining sympathetic ganglion.
They contain myelinated preganglionic sympathetic fibers (GVE and GVA).
Unlike the gray variety, white rami communicantes do not extend below L3.[1]
