Histological and histochemical studies of the lympho reticular and glandular tissues of the pharyngeal region of the one –humped camel (camellus dromedarius)

The lyophareticular and glandular tissues associated with the. pharynx wore studied in ten hoods of adult c aac La, SOi:1plGS were takGn fron thv vc..ntral. dorsal and latercl parteof the pherymal walls as well as froll the ph&ryngeallynphnodes.
