The structure of the salivary glands – Punctates cytology of salivary glands

Salivary glands (parotid, submandibular, sublingual, labial, buccal, lingual, palatine) built by alveolar type or alveolar-tubular gland and consist of secretory (end) departments, generating a secret and excretory ducts.

Depending on the nature of the secret release protein (serous), mucous glands and mixed. So how do they relate to each other next to the transitional forms, a clear distinction between them is not possible.

The ducts of the salivary glands lined cube (Low multi-row seats) , cylindrical, and in the mouth - stratified squamous epithelium.

Cells cubic epithelium Small, round or irregularly round shape, with eccentrically placed nuclei.

Цитологическая картина пунктата слюнной железы

Kernels average or below the average, circular or slightly oval, with clear smooth contours. The nucleoli are not visible. The cytoplasm surrounds the nucleus of a broad rim with clear smooth contours, basophilic, intensely colored, Homogeneous. In some cells the cytoplasm is spotty due enlightenment of various sizes, intensity and shape. Such cells are arranged in a series of short, groups and glandular structures. Sometimes detected punctate epithelial cubic large, painted in light colors.

The cells are columnar epithelium punctate in the salivary glands of the rarely revealed, have normal morphological characteristics.

Serocitы - Cells, producing protein secretion. There may be rounded, cylindrical or goblet shape. The amount depends on the fullness of their cytoplasm secret and ranges from 10 to 20 microns in diameter and more. Hyperchromatic cell nuclei, Small, located in the cell center or eccentrically depending on the cells (functioning or non-functioning).

In afunctional serotsytov cytoplasm neobylnaya, basophilic, while the broader functioning, clearly defined, It contains inclusions secret, colored pale blue, sometimes pinkish tone.

Mucosal (mucous cells) in large punctate, vacuolated, round or irregular polygonal shape. The kernels are small, rounded, sometimes bean-shaped lubricated chromatin structure and irregular contours. They are located eccentrically and characterized hypochromia. There may be a dual-core cell.

Cytoplasm abundant mucosal, basophilic, contains largest high, shape and color of the vacuole. In some cells of small vacuoles, in the other - large. With a large number of vacuoles cell as it is full of secrets. Vacuoles are painted in light gray-pinkish tone. Often large vacuoles surrounded roller basophilic cytoplasm. The edges of the cytoplasm of cells in some clear and painted more intensively, than the central part, and in others - jagged, razlohmachennye. Cells are located separately, strata and groups, sometimes form zhelezistopodobnye structure.

The punctate salivary glands occasionally found myoepitheliocytes, which may be closely associated with the cubic and cylindrical epithelium or glandular structures. The presence of such formations in punctate gives reason to believe, that the material obtained from the salivary glands.
