The salivary glands of Ameiva ameiva (Teiidae, Lacertilia). A morphological, morphometric and histochemical study.

The authors studied morphological, morphometric, and histochemically the mucosubstances and proteins in the salivary glands of the lizard Ameiva. Based on the results, the authors concluded: 1. The labial salivary gland is formed by small mucous and mucoserous glands; the sublingual gland by mucoserous cells. 2. Mucous cells show neutral and sulphated mucosubstances and sialic acid. Mucoserous cells of the labial gland show neutral mucosubstance, sialic acid, hyaluronic acid and protein radicals. Mucoserous cells of the sublingual gland show neutral mucosubstance, sialic acid and protein radicals. 3. The average values for acinar area were: 1,198.11 microns 2 for mucoserous acini and 2,105.95 microns 2 for mucous acini of the labial salivary gland. The average values for nucleus volume were: 47.41 microns 3 for mucoserous cells and 38.97 microns 4 for mucous cells. 4. The average values for acinar area and nuclear volume of the mucoserous cells of the subingual gland were respectively: 1,474.62 microns 2 and 67.77 microns 3.
