ABSTRACT. The submandibular glands sampled from 8 rats (4 males and 4 females) were prepared for histological exams. Aspects concerning density and diameter of the granular tubes, but also the degree of grains deposits of the cells from tubular walls were followed. Differences regarding the degree of grains deposit from the granular cells were observed, even from a tube to another or from a cell to another, both in males and females, without significantly differences between these two sexes. Based on our results, we can say that the sexual dimorphism sustained by some authors was not confirmed by our investigation.
