| urethral pressure profile | The continual recording of pressure through a hole in the side of a small catheter as it is pulled (at a constant rate while either water or a gas is infused through the hole) from a point within the bladder, through the vesical neck, and down the entire urethra; a form of resistance measurement which gives a tracing indicative of the functional length of the urethra and the points of maximal urethral resistance.

|---|---|
| urethral stricture | <urology> A narrowing of the urethra that results from inflammation, injury or infection. (27 Sep 1997) |
| urethral surface of penis | The surface of the penis opposite to the dorsum penis. Synonym: facies urethralis penis. (05 Mar 2000) |
| urethral syndrome | <syndrome, urology> Symptoms of a urinary tract infection although the urine is sterile when analysed. This suggests the infection is localised to the urethra (urethritis). Treated with antibiotics. (27 Sep 1997) |
| urethral valves | Folds in the urethral mucous membrane. See: anterior urethral valve, posterior urethral valves. (05 Mar 2000) |
| accessory lacrimal glands | Small, compound, branched, tubular glands located in the middle part of the lid (Wolfring's glands, 1872, or Ciaccio's glands, 1874) and along the superior and inferior fornices of the conjunctival sac (Krause's glands, 1854). These accessory glands are just scattered scraps of lacrimal gland tissue; all of them produce the same kind of tears and debouch on to the conjunctival surface. Henle's and Baumgarten's "glands" are in fact not glands at all, but mere epithelial invaginations. Synonym: glandulae lacrimales accessoriae. (05 Mar 2000) |
| accessory suprarenal glands | Isolated, often minute, masses of suprarenal tissue sometimes found near the main glands or in the broad ligament or the epididymis. Synonym: glandulae suprarenales accessoriae. (05 Mar 2000) |
| aggregate glands | Lymphoid organs located in the sub mucosal tissue of the mammalian gut containing very high proportions of IgA secreting precursor cells. The patches have B and T dependent regions and germinal centres. A specialised epithelium lies between the patch and the intestine. Involved in gut associated immunity. (18 Nov 1997) |
| agminate glands | Lymphoid organs located in the sub mucosal tissue of the mammalian gut containing very high proportions of IgA secreting precursor cells. The patches have B and T dependent regions and germinal centres. A specialised epithelium lies between the patch and the intestine. Involved in gut associated immunity. (18 Nov 1997) |
| Albarran's glands | Minute submucosal glands or branching tubules in the subcervical region of the prostate gland, emptying for the most part into the posterior portion of the urethra. Synonym: Albarran y Dominguez' tubules. (05 Mar 2000) |
| apocrine glands | Large, branched, specialised sweat glands that empty into the upper portion of a hair follicle instead of directly onto the skin. (12 Dec 1998) |
| apocrine sweat glands | Sudoriferous glands that develop in association with hair follicles and undergo enlargement and secretory development at puberty; they secrete a viscous and odourless sweat that supports the growth of bacteria leading to an acrid odour; secretion is by an eccrine, not apocrine, mechanism. Synonym: axillary sweat glands. (05 Mar 2000) |
| areolar glands | A number of small mammary glands forming small rounded projections from the surface of the areola of the breast; they enlarge with pregnancy and during lactation secrete a substance presumed to resist chapping. Synonym: glandulae areolares, Montgomery's follicles, Montgomery's glands. (05 Mar 2000) |
| arytenoid glands | A large number of mixed glands in the mucous membrane of the larynx; they are called, according to their situation, anterior, middle, and posterior. Synonym: glandulae laryngeae, laryngeal glands. (05 Mar 2000) |
| axillary glands | Numerous nodes around the axillary veins which receive the lymphatic drainage from the upper limb, scapular region and pectoral region (including mammary gland); they drain into the subclavian trunk. Synonym: nodi lymphatici axillares, axillary glands. (05 Mar 2000) |
