Accessory Organs Caudad to each main organ in Narcine there lies a smaller structure that both by electrophysiological and anatomical criteria has now been identified as another, hitherto undescribed, electric organ. This differs significantly in many respects from the main organ and therefore is termed an accessory electric organ. Gross anatom\. The accessory organs arise dorsally in the articulation of the cartilaginous scapular process of each side. They run obliquely ventral and slightly.
