Structural organization and morphometric parameters in system of excretory ducts of human labial glands
Abstract
With the aim of conformity and structural features revealing and space organization of excretory ducts of small salivary glands system of human being, the histology of wall of labial excretory ducts is studied, morphometry of their major size is carried out (external diameter, space, width of wall). In the system of excretory ducts of labial gland of human being, the change of size of their external and internal diameter is revealed, which is seen on the cutting and 3-D models such local sharp narrowing and ampula-shaped widening of ducts. The phenomenon of some excretory ducts spiralization together with their siphon structure has been noted. The general tendency is preserved; it is marked by the existence of the greatest pass ability for secretion within interlobular and common excretory ducts and retention areas in the places of their narrowing. Certain regularity of mutual location of ducts and some chains of hemomicrocirculatory flow. Collector venules are located in place formation agreeably innerlobules, lobules, interlobules. Received morphological results will serve to explaining of the mechanism of the movement of secrete through complect – branching system excretory ducts of the smaller salivary glands of the human organism.
