| septal bone | The tissue intervening between two adjacent pulmonary alveoli; it consists of a close-meshed capillary network covered on both surfaces by very thin alveolar epithelial cells, one of the bony partitions between the tooth sockets. Synonym: septum interalveolare, alveolar septum, septal bone. (05 Mar 2000) |
|---|---|
| septal branches | The interventricular septal branches; branches of the anterior and posterior interventricular arteries distributed to the muscle of the interventricular septum. Synonym: rami interventriculares septales. (05 Mar 2000) |
| septal cartilage | A thin cartilaginous plate located between vomer, perpendicular plate of the ethmoid, and nasal bones, and completing the nasal septum anteriorly. Synonym: cartilago septi nasi, cartilage of nasal septum, cartilaginous septum, pars cartilaginea septi nasi, quadrangular cartilage, septal cartilage. (05 Mar 2000) |
| septal cell | A round pale cell of the lungs in the septa between the pulmonary alveoli. (05 Mar 2000) |
| septal defect, atrial | A hole in the septum, the wall, between the atria, the upper chambers of the heart. Commonly called an asd. Asds are a major class of heart deformity that is present at birth (congenital cardiac malformation). (12 Dec 1998) |
| septal defect, ventricular | A hole in the interventricular septum, the wall between the ventricles, the lower chambers of the heart. Commonly called a vsd. Vsds are a common class of heart deformity that is present at birth (congenital cardiac malformation). (12 Dec 1998) |
| septal gingiva | That portion of the gingiva that covers the interdental septum. (05 Mar 2000) |
| septal lines | Radiographic images of thickened interlobular septa, most often along the lateral border of lung, extending to pleura; Kerley A and B lines; usually caused by septal oedema and fibrosis, also carcinomatosis. (05 Mar 2000) |
| septal nuclei | Neural nuclei situated in the septal region of the diencephalon. (12 Dec 1998) |
| sphenoid process of septal cartilage | The tapering extension of the septal cartilage that lies between the perpendicular plate of the ethmoid and the vomer. Synonym: processus posterior cartilaginis septi nasi, processus sphenoidalis cartilaginis septi nasi, sphenoid process of septal cartilage. (05 Mar 2000) |
| nasal septal cartilage | A thin cartilaginous plate located between vomer, perpendicular plate of the ethmoid, and nasal bones, and completing the nasal septum anteriorly. Synonym: cartilago septi nasi, cartilage of nasal septum, cartilaginous septum, pars cartilaginea septi nasi, quadrangular cartilage, septal cartilage. (05 Mar 2000) |
| defect, atrial septal | A hole in the septum, the wall, between the atria, the upper chambers of the heart. Commonly called an ASD. ASDs are a major class of congenital cardiac malformation. (12 Dec 1998) |
| defect, ventricular septal | Hole in the interventricular septum, the wall between the ventricles (lower chambers of the heart). Commonly called a VSD. VSDs are a common class of heart deformity present at birth (congenital cardiac malformation). (17 Dec 1998) |
| ambiguous atrioventricular connections | Connections in which half the atrioventricular junction is connected concordantly and the other half is discordantly connected. (05 Mar 2000) |
| anomalous atrioventricular excitation | Ectopic atrial beat conducted to the ventricle. (05 Mar 2000) |
