The salivary glands in many vertebrates including mammals are exocrine glands that produce saliva through a system of ducts.Humans have three paired major salivary glands (parotid, submandibular, and sublingual), as well as hundreds of minor salivary glands. [1]
The parotid gland is a major salivary gland in many animals. In humans, the two parotid glands are present on either side of the mouth and in front of both ears.They are the largest of the salivary glands.
In mammals, invertebrates and most fish, [1] [2] the anus (pl.: anuses or ani; from Latin, 'ring' or 'circle') is the external body orifice at the exit end of the digestive tract (), i.e. the opposite end from the mouth.
Blockage of the main parotid duct, or one of its branches, is often a primary cause of acute parotitis, with further inflammation secondary to bacterial superinfection.The blockage may be from a salivary stone, a mucous plug, or, more rarely, by a tumor, usually benign.
Salt gland of a bird and its inner structure Magellanic penguin. The avian salt gland has two main ducts: a medial and a lateral. Salt gland activations occurs from increased osmolarity in the blood, stimulating the hypothalamic information processing, sending a signal through the parasympathetic nerve activating vasodilation, the release of hormones (acetylcholine and vasoactive intestinal ...
Bulbourethral glands are located posterior and lateral to the membranous portion of the urethra at the base of the penis, between the two layers of the fascia of the urogenital diaphragm, in the deep perineal pouch.
Sweat glands, also known as sudoriferous or sudoriparous glands, from Latin sudor 'sweat', [6] [7] are small tubular structures of the skin that produce sweat.Sweat glands are a type of exocrine gland, which are glands that produce and secrete substances onto an epithelial surface by way of a duct.
The Skene's glands' openings are located in the vestibule of the vulva, around the lower end of the urethra. [2] The two Skene's ducts lead from the Skene's glands to the vulvar vestibule, to the left and right of the urethral opening, from which they are structurally capable of secreting fluid.
