The general visceral afferent fibers (GVA, or parasympathetic afferent fibers), conduct sensory impulses from the viscera through the rami communicantes and posterior roots to the spinal cord.

They are probably limited to the white rami connected with the spinal nerves in two groups, viz., the first thoracic to the second or third lumbar and the second sacral to the fourth sacral nerves.

Examples of nerves containing GVA fibers include the glossopharyngeal nerve and the vagus nerve.[1]
