Ciaccio's glands Ciaccio's glands Ciaccio's glands or Wolfring's glands are small tubular accessory lacrimal glands ("glandulae lacrimales accessoriae") found in the lacrimal caruncle of the eyelid. They are located in the upper border of the tarsus, approximately in the middle between the extremities of the tarsal glands. Sometimes they are situated slightly above the tarsus. There are usually 2 to 5 of these glands in the upper eyelid, and their function is to produce tears which are secreted onto the surface of the conjunctiva. They are named after Italian anatomist Giuseppe Vincenzo Ciaccio (1824–1901), who described these glands in 1874. They are
Brunner's glands Brunner's glands Brunner's glands (or duodenal glands) are compound tubular submucosal glands found in that portion of the duodenum which is above the hepatopancreatic sphincter (a.k.a. sphincter of Oddi). The main function of these glands is to produce a mucus-rich alkaline secretion i.e. Mucous (containing bicarbonate) in order to: They also secrete urogastrone, which inhibits parietal and chief cells of the stomach from secreting acid and their digestive enzymes. This is another form of protection for the duodenum. They are the distinguishing feature of the duodenum, and are named for the Swiss physician who first described them, Johann Conrad Brunner.
