| descendens hypoglossi | The fibres that arise from the first and second cervical nerves, accompany the hypoglossal nerve, then branch off to meet the inferior root in the ansa cervicalis; they innervate the infrahyoid muscles. Synonym: descendens hypoglossi, descending branch of hypoglossal nerve, radix superior ansae cervicalis. (05 Mar 2000) |

| tractus descendens nervi trigemini | <anatomy, nerve> A compact fibre bundle, comma-shaped on transverse section, composed of primary sensory fibres of the portio major of the trigeminal nerve, descending from the level of the entrance of the trigeminus in the upper pons down through the dorsolateral region of the rhombencephalic tegmentum along the lateral side of the descending or spinal nucleus of the trigeminus, emerging on the dorsolateral surface of the lower medulla oblongata as the tuberculum cinereum, and continuing as far as the second cervical segment of the spinal cord. Its fibres are distributed to the descending or spinal nucleus of the trigeminus. Synonym: tractus spinalis nervi trigemini, descending tract of trigeminal nerve, tractus descendens nervi trigemini.

| abdominal aorta | <anatomy> The largest arterial conduit below the diaphragm. This term refers to the portion of the aorta below the diaphragm to the bifurcation into the right and left common iliac arteries. It supplies blood to the abdominal viscera, pelvic organs and lower extremities. (20 Jun 2000) |
| abdominal part of aorta | <anatomy> The largest arterial conduit below the diaphragm. This term refers to the portion of the aorta below the diaphragm to the bifurcation into the right and left common iliac arteries. It supplies blood to the abdominal viscera, pelvic organs and lower extremities. (20 Jun 2000) |
| aorta | <anatomy> The largest artery in the body which has its origin at the heart. It gives off branches to the extremities, neck and major organs for the purpose of supplying oxygenated blood. (27 Sep 1997) |
| aorta abdominalis | <anatomy> The largest arterial conduit below the diaphragm. This term refers to the portion of the aorta below the diaphragm to the bifurcation into the right and left common iliac arteries. It supplies blood to the abdominal viscera, pelvic organs and lower extremities. (20 Jun 2000) |
| aorta angusta | Congenital narrowness of aorta. (05 Mar 2000) |
| aorta ascendens | The part of the aorta prior to the aortic arch from which arise the coronary arteries. Synonym: aorta ascendens, ascending part of aorta, pars ascendens aortae. (05 Mar 2000) |
| aorta, thoracic | The portion of the descending aorta proceeding from the arch of the aorta and extending to the diaphragm. (12 Dec 1998) |
| aorta thoracica | The part of the descending aorta that supplies structures as far down as the diaphragm. Synonym: pars thoracica aortae, aorta thoracica, thoracic part of aorta. (05 Mar 2000) |
| arch of the aorta | The curved portion between the ascending and descending parts of the aorta; it begins as a continuation of the ascending aorta posterior to the sternal angle, runs posteriorly and slightly to the left as it passes over the root of the left lung, and becomes the descending aorta as it reaches and begins to course along the vertebral column; it gives rise to the brachiocephalic trunk, the left common carotid and left subclavian arteries. Any member of the several pairs of arterial channels encircling the embryonic pharynx in the mesenchyme of the brachial arches; there are potentially six pairs, but in mammals the fifth pair is poorly developed or absent. The first and second pairs are functional only in very young embryos; the third pair is involved in the formation of the carotids; the fourth arch on the left is incorporated in the arch of the aorta; the sixth pair forms the proximal part of the pulmonary arteries. A series of arterial channels encircling the embryonic pharynx in the mesenchyme of the branchial arch's. There are potentially six pairs, but in mammals the fifth pair is poorly developed or absent. The first and second pairs are functional only in very young embryos; the third pair is involved in the formation of the carotids; the fourth arch on the left is incorporated in the arch of the aorta; the sixth pair forms the proximal part of the pulmonary arteries. Synonym: arcus aortae. (05 Mar 2000) |
| arteria aorta | <anatomy> The largest artery in the body which has its origin at the heart. It gives off branches to the extremities, neck and major organs for the purpose of supplying oxygenated blood. (27 Sep 1997) |
| ascending aorta | The part of the aorta prior to the aortic arch from which arise the coronary arteries. Synonym: aorta ascendens, ascending part of aorta, pars ascendens aortae. (05 Mar 2000) |
| ascending part of aorta | The part of the aorta prior to the aortic arch from which arise the coronary arteries. Synonym: aorta ascendens, ascending part of aorta, pars ascendens aortae. (05 Mar 2000) |
| bifurcation of aorta | The division of the aorta into right and left common iliac arteries; it occurs at the level of the fourth and fifth lumbar vertebral body. Synonym: bifurcatio aortae. (05 Mar 2000) |
