Exocrine Gland

 

in animals and humans, a gland that secretes the substances it forms through ducts onto the surface of the body or of mucous membranes or into a cavity. Exocrine glands include the sebaceous, salivary, sweat, mammary, lacrimal, and musk glands, as well as the liver, glands of the gastrointestinal tract, and other glands that release secretions into the alimentary canal.

(2009a) provide evidence that CBC is present in substantial amounts in juvenile plants and declines with maturation; these authors found variants in which CBC persisted into maturity, and noticed that this is associated with a reduced presence of perigonal bracts and secretory glands. CBG rarely dominates the resin of Cannabis (Fournier et al., 1987).
The natural function of the abundant secretory glands, and of the large volume of resin they produce, has not been established.
Epidermal secretory glands are present on all of the preceding structures, explaining the presence of cannabinoids.
The absolute quantity of cannabinoids produced by an individual plant or by a population (on an average basis) depends on growth and development traits (such as size and proportion of tissues constituted by secretory glands), which are (a) probably determined polygenically, (b) are unrelated to cannabinoid biosynthetic pathways, and (c) are subject to strong environmental modification.
It is predominantly prepared by filtering cannabis material through very fine fabric screens (such as silk) or sieves, and mechanically agitating the material to collect a resinous or powdery material with a higher concentration of the plant's secretory glands than in conventional marijuana.
Stickiness of the secretory glands is due to terpene secretions over the outer surface of the glands.
The Asian tradition of using filters is employed, but the millipore screens now commonly used have much smaller openings (50150 microns in diameter), and the techniques utilized produce a material that is very much richer in presence of secretory glands, very much lower in presence of other herbal material, and is (usually) higher in THC, by comparison with conventional Asian hashish.
Secretory glands observed in peripheral regions of the collagenous layer and epidermis were morphologically similar to Type II/III cells reported previously in the leech, Theromyzon tessulatum (Sayers et al., 2009).
While a woman's menstrual cycle advances toward ovulation, the endometrial lining increases significantly in mass as the uterine tissue develops the vasculature and secretory glands needed to sustain an implanted embryo.
