Abstract EN

The nasal septal island (NSI) is a sensory patch of neuroepithelium located within the soft tissue of the nasal septum in dromedaries.

The island has unique anatomical features, including the specialized subepithelial glands.

The aim of the present study was to describe the microscopic features and ultrastructure of these subepithelial glands and to speculate the possible functions.

A total of 10 camel heads were used for the study.

Unlike the serous and mucous airway glands, the NSI glands' ultrastructural features were typical for cells of the (Amine Precursor Uptake and Decarboxylation, APUD) system.

These features were included, membrane bound secretory vesicles of varying electron density, smooth endoplasmic reticulum in the form of vesicles; electron dense mitochondria, abundant rough endoplasmic reticulum and free ribosomes.

Alcian-PAS identifiable mucus granules were not observed, except for few clusters of cells, located at the luminal surface.

The probable functions were discussed on basis of cellular morphology and context.

In a conclusion, the NSI subepithelial glands in dromedaries had unique anatomical structures, and as many other APUD cells, they had the machinery required for synthesis of a variable number of biologically active peptides, amines and chemical mediators.
