| posterior intercostal arteries | Terminal branches of the superior intercostal artery (from costocervical trunk) supplying upper two intercostal spaces (1-2). Posterior intercostal arteries 3-11, one of nine pairs of arteries arising from the thoracic aorta and distributed to the nine lower intercostal spaces, vertebral column, spinal cord, and muscles and integument of the back; they anastomose with branches of the musculophrenic, internal thoracic, superior epigastric, subcostal and lumbar. Synonym: arteriae intercostales posteriores. (05 Mar 2000) |
| posterior intercostal veins | 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) |
| superior intercostal artery | <anatomy, artery> Origin, costocervical trunk; distribution, structures of first and second intercostal spaces via its terminal branches, posterior intercostal arteries 1 and 2; anastomoses, anterior intercostal branches of internal thoracic. Synonym: arteria intercostalis suprema, highest intercostal artery, supreme intercostal artery. (05 Mar 2000) |
| supreme intercostal artery | <anatomy, artery> Origin, costocervical trunk; distribution, structures of first and second intercostal spaces via its terminal branches, posterior intercostal arteries 1 and 2; anastomoses, anterior intercostal branches of internal thoracic. Synonym: arteria intercostalis suprema, highest intercostal artery, supreme intercostal artery. (05 Mar 2000) |
| dorsal branch of the posterior intercostal arteries 3-11 | Terminal branch (with ventral branch) of the 3rd through 11th posterior intercostal arteries, distributed to thoracic portion of posterior vertebral column, spinal cord and environs, and back. Synonym: ramus dorsalis arteriarum intercostalium posteriorum III-XI. (05 Mar 2000) |
| dorsal branch of the posterior intercostal veins 4-11 | Major tributary of the 4th through 11th posterior intercostal veins; area drained is the same as that supplied by the dorsal branch of posterior intercostal arteries. Synonym: ramus dorsalis venarum intercostalium posteriorum IV-XI. (05 Mar 2000) |
| dorsal branch of the superior intercostal artery | <anatomy, artery> Branches of the 1st and 2nd posterior intercostal arteries which arise as branches of the supreme intercostal artery. The distribution is the same as for the dorsal branches of the other posterior intercostal arteries at the T1-T2 vertebral level. Synonym: rami dorsales arteriae intercostalis supremae. (05 Mar 2000) |
| innermost intercostal muscle | <anatomy> A layer parallel to and essentially part of the internal intercostal muscle but separated from it by the intercostal vessels and nerves.internal intercostal muscle for attachment, action and nerve supply. Synonym: musculus intercostalis intimus. (05 Mar 2000) |

| intercostal anaesthesia | Regional anaesthesia produced by injection of local anaesthetic solution about intercostal nerves. (05 Mar 2000) |
| intercostal arteries | Arteries which course in the thoracic wall between ribs. See: anterior intercostal arteries, posterior intercostal arteries 1-2, posterior intercostal arteries 3-11, superior intercostal artery. (05 Mar 2000) |
| intercostal ligaments | The membranous layers between ribs. Synonym: membranae intercostalia, intercostal ligaments, ligamenta intercostalia. (05 Mar 2000) |
| intercostal lymph nodes | 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) |
| intercostal membranes | The membranous layers between ribs. Synonym: membranae intercostalia, intercostal ligaments, ligamenta intercostalia. (05 Mar 2000) |
