| Embden-Meyerhof-Parnas pathway | A pathway that degrades glucose to pyruvate, the six-carbon stage converts glucose to fructose-1,6-bisphosphate, and the three-carbon stage produces ATP while changing glyceraldehyde-3-phosphate to pyruvate. Compare: Entner-Doudoroff pathway. (09 Oct 1997) |
|---|---|
| Embden-Meyerhof pathway | The main pathway for anerobic degradation of carbohydrate. Starch or glycogen is hydrolysed to glucose 1 phosphate and then through a series of intermediates, yielding two ATP molecules per glucose and producing either pyruvate which feeds into the tricarboxylic acid cycle) or lactate. (18 Nov 1997) |
| Entner-Douderoff pathway | A degradative pathway for carbohydrates in certain microorganisms (e.g., Pseudomonas sp.) that lack hexokinase, phosphofructokinase, and glyceraldehyde-3-phosphate dehydrogenase. (05 Mar 2000) |
| Entner-Doudoroff pathway | <biochemistry> A pathway that converts glucose to pyruvate and glyceraldehyde-3 phosphate by producing 6-phosphogluconate and then dehydrating it. (09 Oct 1997) |
| extrinsic pathway | <haematology> Initiation of blood clotting as a result of factors released from damaged tissue, as opposed to contact with a foreign surface (the intrinsic pathway). Tissue thromboplastin (Factor III) in conjunction with Factor VII proconvertin) will activate Factor X that, once activated, converts prothrombin to thrombin. (27 Jun 1999) |
| 4-aminobutyrate pathway | The pathway that ultimately converts 4-aminobutyrate to succinate; succinate is then converted to alpha-ketoglutarate, via the tricarboxylic acid cycle, which is then acted upon by glutamate dehydrogenase; glutamate is then decarboxylated to reform 4-aminobutyrate; an important pathway for those cells which make this neuroactive molecule. Synonym: GABA pathway. (05 Mar 2000) |
| lysogenic pathway | <virology> The method by which a virus becomes a dormant, passive part of its host bacterium's genome (a lysogenic virus), choosing to insert its DNA into the host's and postponing completion of its lytic cycle, at which time it destroys the host and spreads its progeny to infect other bacterial cells (enters the lytic pathway). (09 Oct 1997) |
| lytic pathway | The steps in the method that a virus takes to complete a lytic cycle, including the production and assembly of progeny viruses with host cell machinery and the destruction of the host cell by rupturing its plasma membrane (lysis), releasing the progeny viruses in the process. (09 Oct 1997) |
| 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) |
| ampulla of lacrimal canaliculus | A slight dilation at the angle of the lacrimal canaliculus immediately beyond the lacrimal punctum. Synonym: ampulla canaliculi lacrimalis. (05 Mar 2000) |
| anastomotic branch of middle meningeal artery to lacrimal artery | <anatomy, artery> A branch of the middle meningeal artery arising in the cranial cavity which runs anteriorly through the superior orbital fissure to anastomose with the lacrimal artery. See: orbital branch of middle meningeal artery. Synonym: ramus anastomoticus arteriae meningeae mediae cum lacrimali. (05 Mar 2000) |
| anterior lacrimal crest | A vertical ridge on the lateral surface of the frontal process of the maxilla that forms part of the medial rim of the orbit. Synonym: crista lacrimalis anterior. (05 Mar 2000) |
| palpebral part of lacrimal gland | palpebral part of lacrimal gland |
| communicating branch of lacrimal nerve with zygomatic nerve | <anatomy, nerve> Nerve branch by which postsynaptic parasympathetic (secretomotor) fibres from the pterygopalatine ganglion are transferred from the zygomatic nerve to the lacrimal nerve (heretofore purely sensory) for distribution to the lacrimal gland. Synonym: ramus communicans nervi lacrimalis cum nervo zygomatico. (05 Mar 2000) |
| posterior lacrimal crest | A vertical ridge on the orbital surface of the lacrimal bone which, together with the anterior lacrimal crest, bounds the fossa for the lacrimal sac. Synonym: crista lacrimalis posterior. (05 Mar 2000) |
