| pituicyte | Dominant intrinsic cells of the neural lobe of the hypophysis. Have long branching processes and resemble neuroglia: secrete antidiuretic hormone. (18 Nov 1997) |
| pituicytoma | <tumour> A rare gliogenous neoplasm derived from pituicytes, occurring in the posterior lobe of the pituitary gland and characterised by cells with relatively small, round or oval nuclei and long branching processes that form a complex network of cytoplasmic material, in which numerous small droplets of fat may be demonstrated. Origin: pituicyte + G. -oma, tumour (05 Mar 2000) |

| pituitary | <anatomy, endocrinology> An endocrine gland located at the base of the brain, in the small recess of a bone - certain sections of the pituitary each secretes important hormones including growth hormone (GH) and antidiuretic hormone (ADH). (16 Dec 1997) |
| pituitary adamantinoma | <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) |
| pituitary adenoma | <radiology> Benign, slow-growing, arises from adenohypophysis (anterior lobe), 5-18% of all intracranial neoplasms plain film (unreliable): enlargement of sella and sloping of the sella floor, erosion of the anterior and posterior clinoid, erosion of the dorsum sellae, calcified in less than10%, may present as a mass in the nasopharynx functioning microadenoma, less than10 mm, 20-30% of pituitary adenomas, types: prolactinoma, corticotrophic adenoma, somatotrophic adenoma, nonfunctioning macroadenoma, more than 10 mm, 70-80% of pituitary adenomas (12 Dec 1998) |
| pituitary ameloblastoma | <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) |
| pituitary apoplexy | Sudden haemorrhage into or ischemic necrosis of a normal or adenomatous pituitary gland. (12 Dec 1998) |

| pitchblende |
Uraninite is a uranium-rich mineral with a composition that is largely UO2 (uranium oxide), but which also contains UO3 and oxides of lead, thorium, and rare earths. It is most commonly known in the variety pitchblende. All uraninite minerals contain a small amount of radium as a radioactive decay product of uranium; it was in pitchblende from the J?hymov in Czechoslovakia that Marie Curie discovered radium. ...

| pith |
Pith is a light substance that is found in vascular plants. It consists of soft, spongy parenchyma cells, and is located in the center of the stem or root. It is encircled by a ring of xylem (woody tissue), and outside that, a ring of phloem (bark tissue). In most plants the pith is solid, but some plants, e.g. grasses and umbellifers, the pith has a hollow centre forming a hollow tube except at the points where leaves are produced, where there is a solid plate across the stem. ...

| pituitary |
The pituitary gland, or hypophysis, is an endocrine gland about the size of a pea that sits in the small, bony cavity (sella turcica) at the base of the brain. Its posterior lobe is connected to a part of the brain called the hypothalamus via the infundibulum (or stalk), giving rise to the tuberoinfundibular pathway. The posterior lobe is thus derived from neural ectoderm while the anterior lobe is derived from oral ectoderm. ...
