Aim: The aim of this study was to describe the patterns of arterial
distribution to the submandibular and sublingual salivary glands in
the golden hamster (Mesocricetus auratus). Methods: We adopted the
technique of acryl plastic injection. A low-viscosity acrylic resin
was injected transcardially. The tissues around the vessels in the
head and neck region were then digested in hot alkali, and the
resulting casts were examined under a binocular dissecting
microscope. The lengths and diameters of the arterial glandular
branches were measured using a sliding caliper. Results: 1) The main
arterial branch of the submandibular salivary gland originated from
the facial artery, and a supplemental branch emerged from the
submental artery inconstantly. 2) The major sublingual salivary
gland was supplied with the submandi¬bular lymph node branch.
Conclusion: Determining the main blood vessels of the submandibular
and sublingual salivary glands is very important, especially for the
surgical application. |
