| plastic section stain | <technique> For electron microscopy, a stain (e.g., osmic acid, PTA, potassium permanganate) used on thin sections of plastic-embedded tissues, utilizing differential attachment of heavy atoms to various cellular and tissue structures so that electrons will be absorbed and scattered by these structures to produce an image; to achieve differential staining, the stain must penetrate nonwettable plastic embedments, for light microscopy, a stain (e.g., alkaline toluidine blue, silver methenamine) used on plastic-embedded tissues to attain higher resolution and more detail than normally possible; semi-thick (0.5-1.5 um) sections are particularly useful in renal pathology, especially in combination with the phase microscope.

| tissue culture plastic | <cell culture> Polystyrene that has been rendered wettable by oxidation, a treatment that increases its adhesiveness for cells from animal tissues and without which anchorage dependent cells will not grow. Commercially achieved by treatment known as glow discharge. (18 Nov 1997) |
| Broca's pouch | A pear-shaped encapsulated collection of connective tissue and fat in each labium majus. Synonym: Broca's pouch. (05 Mar 2000) |
| paracystic pouch | A peritoneal depression formed by the reflection of the peritoneum from the lateral pelvic wall onto the roof of the bladder; in the female, it is the lateral portion of the uterovesical pouch, separated from the pararectal pouch by the broad ligament. Synonym: fossa paravesicalis, paracystic pouch, paravesical pouch. (05 Mar 2000) |
| Rathke's pouch | A tubular outgrowth of ectoderm from the stomodeum of the embryo; it grows dorsad toward the infundibular process of the diencephalon, around which it forms a cup-like mass, giving rise to the pars distalis and pars juxtaneuralis of the hypophysis. Synonym: craniopharyngeal canal, hypophyseal pouch, Rathke's diverticulum, Rathke's pocket, Rathke's pouch. (05 Mar 2000) |
| Rathke's pouch tumour | <oncology, tumour> A form of primary brain tumour which develops in the pituitary gland. These tumours often secrete increased quantities of pituitary hormones (for example growth hormone) which can result in conditions such as gigantism and acromegaly. They are often benign and rare and comprise less than 5% of childhood brain tumours. Other symptoms include vision changes, headache and weight gain. Treatment often includes a combination of surgery and radiation therapy. (27 Sep 1997) |
| pararectal pouch | A peritoneal depression on either side of the rectum formed by peritoneal (sacrogenital) folds passing from the posterolateral pelvic wall to the central pelvic viscera. The fossa is a lateral extension of the male rectovesical pouch or the female rectouterine pouch. Synonym: pararectal pouch. (05 Mar 2000) |
| paravesical pouch | A peritoneal depression formed by the reflection of the peritoneum from the lateral pelvic wall onto the roof of the bladder; in the female, it is the lateral portion of the uterovesical pouch, separated from the pararectal pouch by the broad ligament. Synonym: fossa paravesicalis, paracystic pouch, paravesical pouch. (05 Mar 2000) |
| rectouterine pouch | <anatomy> A pocket formed by the deflection of the peritoneum from the rectum to the uterus. Synonym: excavatio rectouterina, cavum douglasi, cul-de-sac, Douglas' cul-de-sac, Douglas' pouch, pouch of Douglas, rectovaginouterine pouch. (05 Mar 2000) |
| rectovaginouterine pouch | <anatomy> A pocket formed by the deflection of the peritoneum from the rectum to the uterus. Synonym: excavatio rectouterina, cavum douglasi, cul-de-sac, Douglas' cul-de-sac, Douglas' pouch, pouch of Douglas, rectovaginouterine pouch. (05 Mar 2000) |
