In dogs, this substance is used primarily to mark territory, as a form of communication, or to express extreme fear. Ordinarily, the dog anal glands are emptied out ("expressed") during defecation, when the pressure of the stool presses on the glands so that some of the secretion is depos...
It is a definite possibility that organs which are primarily elements of functional systems other than the reproductive system are involved in sexual maturation. The adrenal glands are attractive candidates for such a role in sexual maturation: they are capable of producing androgens, oestrogens and ...
3Site of Pheromone Biosynthesis There is much variability among insects in the anatomical location of pheromone production, just as there are many differences in the gross morphology and function of pheromone producing tissue. Complexity varies from simple unicellular glands distributed throughout theinteg...
(B) it forms the lining of wet surfaces like buccal cavity and oesophagus (C) it occurs in the ducts of sweat glands (D) it forms the lining of salivary glands and sweat glands (E) it is a loose connetive tissue Which of the above are associated with simple epithelial tissue ?
Tears are an essential fluid that serves different functions, such as washing all the irritating substances that may be present in the eye; also, tears contain bacterial enzymes that prevent microbial infections in the eyes. In addition, tears prevent the drying of...
True Brunner gland adenoma and adenocarcinoma are thought to be rare but typically demonstrate transition from normal Brunner glands to adenomatous or adenocarcinomatous tissue ▪ Heterotopic gastric mucosa • Generally small mucosal lesions that are polypoid and are composed of recognizable gastric mucos...
2i, arrowheads in the right panel), while those of the luminal cuboidal cells were rounded (Fig. 2i, arrows in the right panel). These results indicate that myoepithelial cells are distinguishable from other cell types based on their cellular and nuclear morphologies on 3D live-tissue imaging...
The principal clinical consequence of obstructive MGD is evaporative DE syndrome. Moreover, chronic obstruction of the meibomian glands may also result in degeneration of the secretory gland tissue that can lead to a secondary hypo-secretion even if the primary obstruction is later resolved by ...
of which is separated by a connective tissue septum. Each salivary gland is made up of two separate parts: a serous portion, responsible for secreting watery saliva, and a mucous portion, responsible for a more viscous fluid. The three major salivary glands are all composed of a mixture of ...
Thus, all honey bee membranes contain a mix of phytosterols and 24MC and other phytosterols are integral components of the membranes of HPGs and MDGs. This complicates the identification of the gland that adds 24MC to food jelly as a distinction needs to be made between ‘membrane’ sterols...
