Anatomic study of the arterial model of vessels responsible for the blood supply of neotropic primate´s submandile gland [<em>Cebus apella</em>, Linnaeus 1766]

Abstract

Anatomic aspects of arteries responsible for Cebus apella salivary gland blood supply were studied. The technique utilized was cannulation of the aorta, injection of latex, fixation and dissection of 30 adult monkey antimeres (containing 30 main glands and 3 acessory glands, in a total of 33 glands) belonging to the FMVZ/USP. The facial artery penetrates the mandibular trigon providing single branche to the gland. In one specimen two branches were provided to the left antimer (3,03%). A variety of zero to five collateral branches to the left antimer, and of zero to four to the right antimer were observed. The main artery ends in a single branch (9,09%), in bifurcation (69,7%), in trifurcation (18,18%) and in quadrifurcation (3,03%). The distribution of the branches in the parenchyma had the following directions: cranial, caudal, lateral, medial and recurring. The data obtained permitted to trace a vascular pattern for this gland in Cebus apella
