| periodontal ligament fibres | The collagen fibre's, running from the cementum to the alveolar bone, that suspend a tooth in its socket; they include apical, oblique, horizontal, and alveolar crest fibre's, indicating that the orientation of the fibre's varies at different levels. (05 Mar 2000) |
|---|---|
| periodontal membrane | <anatomy> Fibrous connective tissue surrounding the root of a tooth that separates it from and attaches it to the alveolar bone. (12 Dec 1998) |
| periodontal pocket | An abnormal extension of a gingival sulcus accompanied by the apical migration of the epithelial attachment and bone resorption. (12 Dec 1998) |
| periodontal probe | A calibrated instrument used to measure the depth and topography of periodontal pockets. (05 Mar 2000) |
| periodontal prosthesis | Any restorative and replacement device that is used as a therapeutic aid in the treatment of periodontal disease. It is an adjunct to other forms of periodontal therapy and does not cure periodontal disease by itself. (boucher's clinical dental terminology, 3d ed) (12 Dec 1998) |
| Russell's Periodontal Index | An index that estimates the degree of periodontal disease present in the mouth by measuring both bone loss around the teeth and gingival inflammation; used frequently in the epidemiological investigation of periodontal disease. (05 Mar 2000) |
| lateral mammary branches of lateral cutaneous branches of intercostal nerves | Branches arising from the lateral cutaneous branches of the ventral primary rami of spinal nerves (intercostal nerves) T-3 to T-6 which run anteriorly to supply the lateral aspect of the breast. Synonym: rami mammarii laterales rami cutanei lateralis nervorum thoracicorum, rami mammarii laterales rami cutanei lateralis nervorum intercostalium, lateral mammary branches of lateral cutaneous branches of intercostal nerves. (05 Mar 2000) |
| lateral mammary branches of lateral cutaneous branches of thoracic spinal nerves | Branches arising from the lateral cutaneous branches of the ventral primary rami of spinal nerves (intercostal nerves) T-3 to T-6 which run anteriorly to supply the lateral aspect of the breast. Synonym: rami mammarii laterales rami cutanei lateralis nervorum thoracicorum, rami mammarii laterales rami cutanei lateralis nervorum intercostalium, lateral mammary branches of lateral cutaneous branches of intercostal nerves. (05 Mar 2000) |
| lateral mammary branches of lateral thoracic artery | <anatomy, artery> Branches of the lateral thoracic artery which extend around the lateral borders of the pectoral muscles to supply the lateral aspect of the breast and mammary gland. Synonym: rami mammarii laterales arteriae thoracicae lateralis. (05 Mar 2000) |
| lateral vein of lateral ventricle | A vein draining deep portions of the temporal and parietal lobes; it runs in the lateral wall of the lateral ventricle to terminate in the superior thalamostriate vein. Synonym: vena ventriculi lateralis lateralis, lateral atrial vein, lateral vein of lateral ventricle. (05 Mar 2000) |
| adrenal cyst | <radiology> Same characteristics as renal cysts, but less common, thick wall, septations, calcifications suggests pseudocyst (12 Dec 1998) |
| adventitious cyst | 1. An accumulation of fluid in a cystlike loculus, but without an epithelial or other membranous lining. Synonym: adventitious cyst, false cyst. 2. A cyst whose wall is formed by a host cell and not by a parasite. 3. A mass of 50 or more Toxoplasma bradyzoites, found within a host cell, frequently in the brain; formerly called a pseudocyst, but now considered a true cyst enclosed in its own membrane within the host cell that may rupture to release particles that form new cysts, and apparently is infective to another vertebrate host. See: bradyzoite. Origin: pseudo-+ G. Kystis, bladder (05 Mar 2000) |
| allantoic cyst | Cyst occurring in a persistent portion of the urachus, presenting as an extraperitoneal mass in the umbilical region. It is characterised by abdominal pain, and fever if infected. It may rupture, leading to peritonitis, or it may drain through the umbilicus. (12 Dec 1998) |
| alveolar hydatid cyst | A hydatid cyst of a multiloculate type, usually in the liver, caused by Echinococcus multilocularis, adults of which are in foxes; larvae (alveolar hydatid) are found chiefly in microtine rodents, but also among humans such as trappers and others handling pelts of infected foxes and other carnivores; growth is by exogenous budding and is not limited by an outer laminated membrane as in the hydatid cyst from E. Granulosus; necrosis, cavitation, contiguous spread, and death usually ensue. Synonym: multilocular hydatid cyst, multiloculate hydatid cyst. (05 Mar 2000) |
| aneurysmal bone cyst | <radiology> ABC, 10 - 30 yrs, 75% before skeletal maturity, sites: long bones; also, flat bones Findings: metaphyseal if unfused, metaepiphyseal after fusion, lytic, expansile, thin, continuous rim, thin internal bony strands (12 Dec 1998) |
