| arteriae intercostales posteriores I et II | posterior intercostal arteries 1-2 |
|---|---|
| arteriae intercostales posteriores III-XI | posterior intercostal arteries 3-11 |
| rami intercostales anteriores | One of the arteries supplying the anterior portions of the intercostal spaces of the thoracic wall. Anterior intercostal arteries 1-6 arise as branches of the internal thoracic artery; 7-11 arise as branches of the musculophrenic artery. Synonym: rami intercostales anteriores, rami intercostalis anteriores arteria thoracica interna. (05 Mar 2000) |
| venae intercostales anteriores | Tributaries to the musculophrenic or internal thoracic veins from the anterior portions of intercostal spaces. Synonym: venae intercostales anteriores. (05 Mar 2000) |
| venae intercostales posteriores | Veins draining the intercostal spaces posteriorly; those of the first 1-C space drain into the brachiocephalic veins; from spaces 2-3 they drain into right and left superior intercostal veins; from the fourth to the eleventh spaces on the right they are tributaries of the azygos vein; on the left they empty into either the hemiazygos or accessory hemiazygos veins. Synonym: venae intercostales posteriores. (05 Mar 2000) |
| musculus intercostales externi | Each arises from lower border of one rib and pass obliquely downward and forward to be inserted into the upper border of rib below; action, contract during inspiration, also maintain tension in the intercostal spaces to resist mediolateral movement; nerve supply, intercostal. Synonym: musculus intercostales externi. (05 Mar 2000) |
| nervi intercostales | The ventral rami of the thoracic nerves from segments t1 through t11. The intercostal nerves supply motor and sensory innervation to the thorax and abdomen. The skin and muscles supplied by a given pair are called, respectively, a dermatome and a myotome. (12 Dec 1998) |
| nodi lymphatici intercostales | One or two small nodes located posteriorly in each intercostal space; they receive lymph from the parietal pleura, intercostal space, and posterior body wall; the nodes in the upper spaces empty into the thoracic duct; the nodes in the lower spaces form a descending intercostal trunk that opens into the cisterna chyli. Synonym: nodi lymphatici intercostales. (05 Mar 2000) |
| annulus fibrocartilagineus membranae tympani | fibrocartilaginous ring of tympanic membrane |
| ramus membranae tympani nervi auriculotemporalis | Sensory branch of the auriculotemporal nerve supplying the external surface of the tympanic membrane. Synonym: ramus membranae tympani nervi auriculotemporalis, nerve of tympanic membrane. (05 Mar 2000) |
| recessus membranae tympani anterior | A slitlike space on the tympanic wall between the anterior malleolar fold and the tympanic membrane. Synonym: recessus membranae tympani anterior, Troltsch's pockets, Troltsch's recesses. (05 Mar 2000) |
| recessus membranae tympani posterior | 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) |
| recessus membranae tympani superior | A space in the mucous membrane on the inner surface of the tympanic membrane between the flaccid part of the membrane and the neck of the malleus. Synonym: recessus membranae tympani superior, Prussak's pouch, Prussak's space. (05 Mar 2000) |
| pars flaccida membranae tympani | Triangular loose part of tympanic membrane between the malleolar folds. Synonym: pars flaccida membranae tympani, flaccid membrane, membrana flaccida, Rivinus' membrane, Shrapnell's membrane. (05 Mar 2000) |
| pars tensa membranae tympani | The greater portion of the tympanic membrane which is tense and firm, contrasting with the small triangular flaccid part of tympanic membrane. Synonym: pars tensa membranae tympani, membrana tensa, membrana vibrans. (05 Mar 2000) |
