| anterior descending artery | <anatomy, artery> Anterior interventricular branch of left coronary artery. Terminal branch (with circumflex coronary artery) of left coronary artery; descends in anterior interventricular groove to apex, anastomosing with posterior interventricular artery. Supplies most of sternal aspect of ventricles and anterior two-thirds of interventricular septum, including atrioventricular bundle of conducting tissue. Synonym: ramus interventricularis anterior arteriae coronariae sinistrae, anterior descending artery. (05 Mar 2000) |
| groove for the descending aorta | A broad, deep, vertical sulcus immediately posterior to the hilus on the mediastinal surface of the left lung, formed as a result of the descending aorta impressing or indenting the lung. (05 Mar 2000) |
| pharyngeal branch of descending palatine artery | <anatomy, artery> May arise as a separate branch or as a continuation of lesser palatine artery. Synonym: ramus pharyngeus arteriae palatini descendens. (05 Mar 2000) |
| posterior descending artery | <anatomy, artery> Posterior interventricular branch of right coronary artery. Continuation of right coronary artery in posterior interventricular sulcus; descends to apex to anastomose with anterior interventricular artery; supplies most of diaphragmatic aspect of ventricles and posterior third of interventricular septum. Synonym: ramus interventricularis posterior arteriae coronariae dextrae, posterior descending artery. (05 Mar 2000) |
| saphenous branch of descending genicular artery | <anatomy, artery> Branch of descending genicular artery supplying skin of the upper part of the medial aspect of the leg; anastomosis: medial inferior genicular artery (articular vascular network of knee). Synonym: ramus saphenus arteriae descendentis genicularis. (05 Mar 2000) |
| descending | Of or pertaining to descent; moving downwards. <astronomy> Descending constellations or signs, that point in a planet's orbit where it intersects the ecliptic in passing southward. <mathematics> Descending series, a series in which each term is numerically smaller than the preceding one; also, a series arranged according to descending powers of a quantity.

| descending artery of knee | <anatomy, artery> Origin, femoral, in adductor canal; distribution, penetrates vastoadductor fascia to supply knee joint and adjacent parts; anastomoses, medial superior genicular, medial inferior genicular, lateral superior genicular, lateral inferior genicular and anterior tibial recurrent arteries, i.e., articular network of knee. Synonym: arteria genus descendens, arteria anastomotica magna, descending artery of knee, great anastomotic artery. (05 Mar 2000) |
| descending branch | Branch of an artery or nerve passing inferiorly. Descending branches have been described for the following: descending branch of hypoglossal nerve, superior root of ansa cervicalis; descending branch of lateral circumflex femoral artery; descending branch of the occipital artery. Synonym: ramus descendens. (05 Mar 2000) |
| descending branch of hypoglossal nerve | 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) |
| descending branch of lateral circumflex femoral artery | <anatomy, artery> A major branch of the lateral circumflex femoral artery accompanying the nerve to the vastus lateralis muscle along the anterior border of that muscle and deep to the rectus femoris muscle, supplying both muscles. Anastomosis: with lateral superior genicular artery, i.e., it contributes to the articular network of the knee. Synonym: ramus descendens arteriae circumflexae femoris lateralis. (05 Mar 2000) |
