Gross and microscopic anatomy of the major salivary glands of the ferret.

The gross and microscopic anatomy of the major salivary glands of the ferret was studied. There were 5 pairs of major salivary glands, parotid, submandibular, sublingua, molar and zygomatic. They were of compound tubuloacinar type and consisted of numerous lobes and lobules. The parotid gland was grossly similar to the parotids in other mammals but histologically it was seromucous as in the carnivores dog and cat. The parotid duct opened into the vestibule of the mouth opposite the upper third premolar tooth. The submandibular gland was single on each side, oval in shape and cervical in position. Histologically it was entirely mucous. The submandibular duct opened at a sublingual papilla in the oral cavity at the side of the frenulum of the tongue. The sublingual gland was the smallest of the major salivary glands. It was single on each side and lay deep to the digastric muscle. It opened by several small ductules into the submandibular duct. It was mainly mucous and did not contain intercalated and striated ducts. The molar gland was located superficially near the angle of the mouth. It was irregularly pyramidal and opened by several small ducts into the vesibule opposite the lower molar teeth. It was predominantly mucous. There were no intercalated or striated ducts. The zygomatic gland was present deep to the masseter and related to the orbit in the infra-temporal fossa. The gland opened by several small ducts into the vestibule opposite the upper molar teeth. It was also predominantly mucous and there were no intercalated or striated ducts.
