| platelet membrane glycoproteins | Surface glycoproteins on platelets which have a key role in haemostasis and thrombosis such as platelet adhesion and aggregation. Many of these are receptors. (12 Dec 1998) |
|---|---|
| mucous membrane | <pathology> The lubricated inner lining of the mouth, nasal passages, vagina and urethra, any membrane or lining which contains mucous secreting glands. (27 Sep 1997) |
| mucous membrane of tympanic cavity | The mucous layer of the tympanic cavity and the structures in it. Synonym: tunica mucosa cavitatis tympani, mucous membrane of tympanic cavity. (05 Mar 2000) |
| pleuropericardial membrane | A tissue fold jutting into the right or left embryonic pericardioperitoneal canal; it separates the developing pericardium from the pleural cavity and is formed by the growth of the common cardinal veins to the midline of the body. Synonym: pericardiopleural membrane, pleuropericardial membrane. (05 Mar 2000) |
| pleuroperitoneal membrane | A tissue fold jutting into the caudal portion of the embryonic pericardioperitoneal canal; it develops into the dorsal portion of the definitive diaphragm and is formed by the lungs growing caudally and the liver expanding cranially. Synonym: pleuroperitoneal membrane. (05 Mar 2000) |
| Corti's membrane | A gelatinous membrane that overlies the spiral organ (Corti) in the inner ear. Synonym: membrana tectoria ductus cochlearis, Corti's membrane, tectorium. (05 Mar 2000) |
| cricothyroid membrane | <anatomy> An elastic membrane which lies anteriorly in the neck adjacent the cricoid cartilage and the first tracheal ring. This is the membrane which is pierced or incised when performing a cricothyroidotomy. (13 Nov 1997) |
| cricotracheal membrane | <anatomy> A midline fibrous band connecting the cricoid cartilage with the first ring of the trachea. Synonym: ligamentum cricotracheale, cricotracheal membrane. (05 Mar 2000) |
| cricovocal membrane | Thicker lower portion of the elastic membrane of the larynx, extending between the cricoid cartilage and the vocal ligaments, the latter actually being a thickening of the free, superior margin of the conus elasticus. Synonym: cricovocal membrane, elastic cone. Synonym: cricothyroid ligament. (05 Mar 2000) |
| posterior atlanto-occipital membrane | The fibrous membrane that attaches between the posterior arch of the atlas and the posterior margin of the foramen magnum. Synonym: membrana atlanto-occipitalis posterior. (05 Mar 2000) |
| croupous membrane | <dermatology> A thick, tough fibrinous exudate on the surface of a mucous membrane or the skin, as seen in diphtheria. Synonym: croupous membrane, neomembrane, plica, pseudomembrane. (05 Mar 2000) |
| posterior recess of tympanic membrane | A narrow pocket in the tympanic wall between the posterior malleolar fold and the tympanic membrane. Synonym: recessus membranae tympani posterior, Troltsch's pockets, Troltsch's recesses. (05 Mar 2000) |
| postsynaptic membrane | That part of the plasma membrane of a neuron or muscle fibre with which an axon terminal forms a synaptic junction; in many instances, at least part of such a small postsynaptic membrane patch shows characteristic morphological modifications such as greater thickness and higher electron-density, believed to correspond to the transmitter-sensitive receptor site of such synapses. (05 Mar 2000) |
| cutaneous layer of tympanic membrane | The thin layer of skin on the external surface of the tympanic membrane. Synonym: cutaneous layer of tympanic membrane. (05 Mar 2000) |
| presynaptic membrane | That part of the plasma membrane of an axon terminal that faces the plasma membrane of the neuron or muscle fibre with which the axon terminal establishes a synaptic junction; many synaptic junctions exhibit structural presynaptic characteristics, such as conical, electron-dense internal protrusions, that distinguish it from the remainder of the axon's plasma membrane. See: synapse. (05 Mar 2000) |
