Some anatomical studies on the innervation of the perineal region in the donkey [equus asinus]

ABSTRACT

The innervation of the perineal region in the donkey of both sexes was described and illustrated during the present investigation. The region was propably innervated via the N. pudendus, the N. rectalis caudalis and the ramus for the M. coccygeus and M. levator ani. The origin, course and distribution for each was fully studied. The possible sites for blockade of the N. rectal is caudalis and R. cutaneus distalis was also determined. Terminology for these nerves was applied according to N. A. V. [1983]
