| bacterial outer membrane proteins | Proteins isolated from the outer membrane of bacteria. (12 Dec 1998) |

| rod outer segment | <ophthalmology, physiology> Major photoreceptor cell of vertebrate retina (about 125 million in a human eye). Columnar cells (about 40m long, 1m diameter) having three distinct regions: a region adjacent to and synapsed with, the neural layer of the retina contains the nucleus and other cytoplasmic organelles, below this is the inner segment, rich in mitochondria, that is connected through a thin neck (in which is located a ciliary body) to the outer segment. The outer segment largely consists of a stack of discs membrane infoldings that are incompletely separated in cones) that are continually replenished near the inner segment and that are shed from the distal end and phagocytosed by the pigmented epithelium. The membranes of the discs are rich in rhodopsin, the pigment that absorbs light. (03 Jul 1999) |
| rod outer segments | The portion of the retinal rod cell between the inner segment and the pigment epithelium layer of the retina. (12 Dec 1998) |
| hair cells, outer | Mechanoreceptors in the organ of corti. In mammals the outer hair cells are arranged in three rows which are further from the modiolus than the single row of inner hair cells. The motile properties of the outer hair cells may contribute actively to tuning the sensitivity and frequency selectivity of the cochlea. (12 Dec 1998) |
| outer cone fibre | Located between the inner segment and the cell body. (05 Mar 2000) |
| outer malleolus | The process at the lateral side of the lower end of the fibula, forming the projection of the lateral part of the ankle; the lateral malleolus is more inferiorly placed then the medial malleolus. Synonym: malleolus lateralis, external malleolus, extramalleolus, outer malleolus. (05 Mar 2000) |
| outer membrane | The larger of the two membranes of a double membrane. (05 Mar 2000) |
| the outer | Ovarian extremity of the oviduct. (05 Mar 2000) |
| Aub-DuBois table | Table of basal metabolic rates in calories per square meter of body surface per hour or day for different ages. (05 Mar 2000) |
| Gaffky table | A numerical rating for the classification of tuberculosis according to the number of tubercle bacilli in the sputum, ranging from 1 (one to four organisms in the whole preparation) to 9 (an average of 100 per field). Synonym: Gaffky scale. (05 Mar 2000) |
| vitreous table | The inner table of one of the cranial bones; it is more compact and harder than the outer table. Synonym: lamina internal ossium cranii. (05 Mar 2000) |
| water table | <ecology> The zone of saturation at the highest average depth during the wettest season, it is at least six inches thick and persists in the soil for more than a few weeks. (09 Oct 1997) |
| contingency table | A tabular cross-classification of data such that subcategories of one characteristic are indicated in rows (horizontally) and subcategories of another are indicated in columns (vertically). (05 Mar 2000) |
| cross-table lateral projection | <radiology> Lateral projection radiography of a supine subject using a horizontal X-ray beam. (05 Mar 2000) |
| inner table of skull | The inner compact layer of the cranial bones. Synonym: lamina interna cranii. (05 Mar 2000) |
