Ultrastructure of Primary Afferent Terminals in the Spinal Cord
Primary afferent fibers (PAF) arborize and terminate in the spinal gray matter with characteristic arborizations and terminal structures. The arborizations blend into the neuropil, i.e., they are tangential in lamina I, sagittally oriented sheets in laminae II and III, discs oriented in the transverse plane in the intermediate zone as well as in the ventral horn, and narrow rostro-caudally oriented bundles in Clarke’s column.
