When mucus, fluid or tissue becomes trapped, a cyst forms. Nabothian cysts are so common that they're considered to be a normal feature of cervical anatomy. Your doctor might discover one incidentally during a pelvic exam. In general, cervical cysts don't cause symptoms and require no treatment. Your doctor might collect a tissue sample (biopsy) to send for lab testing if a cervical cyst or other lesion looks unusual. Other red flags include abnormal vaginal bleeding, pelvic pain or pain during intercourse.
Calcareous ooze is a calcium carbonate mud formed from the hard parts (tests) of the bodies of free-floating organisms.Once this mud has been deposited, it can be converted into stone by processes of compaction, cementation, and recrystallization.owever, calcareous ooze will not accumulate in the very deepest parts of the ocean, even if the surface is teeming with the right sort of organism. The reason for this will be discussed in the next section of this article.
Their bodies consist of skeletons made of a soft material called spongin, and a leathery skin broken by pores. The sponge eats by pumping seawater in through its pores. It filters microscopic plants from the water, and expels the excess water through one or more large holes called oscula. A rough sponge used for washing a car, for instance, is made with coarse crystals, while a fine sponge of the type used for applying makeup is made with very fine crystals. 2  As the celluolose mix cooks, then cools, it becomes a hard, porous block. 3  The sponge block is then soaked in a vat of bleach.
