Scholarcy highlights

  • The preganglionic parasympathetic neurons in the sacral spinal cord of the cat have been demonstrated by retrogade changes following section of the pelvic nerve
  • The sacral parasympathetic nucleus was located in the intermediate region of S‐2 and S‐3
  • The majority of the perikarya were located in the intermediolateral cell column, but a significant number were found in the intermediomedial column
  • The distribution of afferent fibers in the pelvic nerve was demonstrated by chromatolysis in cells of the dorsal root ganglia
  • Retrograde changes were limited to the ganglia of S‐2 and S‐3 in five cats, while a few cells with chromatolysis were found in the S‐1 ganglion of four cats
