Abstract

The present investigation was carried out on 7 adult and 5 foetuses of the one humped camel (Camelus dromedarius ) from which a detailed knowledge on the topography and distribution of the vagus nervein the head, cervical, thoracic and abdominal portions of the body in this species of animal was obtained by fine dissection. It was found that the vagus nerye of the camel detaches a common stem for N. Laryngeus cranialis and N. Laryngeus recurrens, the latter however after giving off the N. Laryngeus caudalis replaces the recurrent nerve in other domestic animals. The distribution of the dorsal and ventral oesophageal vagal nerve trunks on the stomach of the camel was also given in detail.
