الملخص EN

The present study was carried out on 78 camel's fetuses having different measurements, collected from El-Basateen slaughter house in winter.

The CRL ranged from 9 cm to 118 cm.

Half of the specimens (of different CRL) were dissected laterally to determine the changes which occurred upon the pharyngeal diverticulum and atlanto-pharyngeal muscle .The rest of specimens (of different CRL) were sawed sagittally to determine and follow up the changes of the pharyngeal cavity and soft palate.

Externally, the dorsal wall of the pharynx presented a small thin walled median dorsal diverticulum which enlarged in size and divided into rostral and caudal compartments by the M.atlantopharyngeus.

Internally, the nasopharynx was divided by a small transverse fold into a rostral and a caudal compartment.

The soft palate had a small dorsal elevation and a ventral diverticulum called dulla..
