Although this nomenclature has been widely accepted, many standard textbooks still employ confusing terminology. Thus, Ranson2 has a chapter devoted to the sympathetic nervous system. Under a subheading he stated:For many reasons it is convenient to have a name which will designate the sum total of all general visceral neurones, both preganglionic
