Anatomical characteristics of the major salivary glands of puma (Puma concolor Linnaeus, 1771)

Abstract

The morphological knowledge of the salivary glands in wild species is fundamental, since these studiescan be used as conservation strategies, clinical treatments and the preservation of species threatened with extinction. Thus, the aim of the study was to anatomically describe the larger salivary glands: parotid, mandibular, sublingual and molar of the jaguar. For this, two specimens of puma (Puma concolor) were used, after death by road traffic accident, donated by the Clinical Surgical Service Department of the Veterinary Hospital “Dr. Halim Atique “(UNIRP). The animals were fixed with 10% aqueous formaldehyde solution, dissected, descriptively analyzed and photographed. Morphologically, the parotid gland is grayish-yellow in color, distinctly lobulated, and has a semilunar shape. This gland is located in the posterolateral region of the face and at its ventral end we observe the parotid duct. The mandibular gland presents a slightly rounded outline, a grayish color and its surface is covered by a capsule of connective tissue. This gland is located in the posterolateral region of the face and we find the mandibular duct at its ventral end. The monostomatic sublingual gland is located on the rostral border of the mandibular gland and it is covered by the mandibular lymph nodes. The molar gland is a yellowish-gray membranous protuberance, elongated, with rectangular shape and it lies dorsally to the labial commissure. Based on the dissections, we conclude that the morphological and topographic characteristics of salivary glands of puma follow the same structural pattern described for other species of carnivorous mammals (domestic and wild).

“…Esta especie se caracteriza por tener una capa corta de color pardusco en el cuerpo, cola y extremidades con tonos más claros en la región ventral, y orejas ennegrecidas. En la edad adulta, mide aproximadamente 2 m de largo, con un peso corporal entre 34 y 120 kg (1)(2)(3)(4) .…”
