| interatrial foramen secundum | A secondary opening appearing in the upper part of the septum primum in the sixth week of embryonic life, just prior to the closure of the interatrial foramen primum. Synonym: ostium secundum, secondary interatrial foramen. (05 Mar 2000) |

| interatrial septum | The partition separating the upper chambers (the atria) of the heart. (12 Dec 1998) |
| ventricular septal rupture | Rupture of the intraventricular septum of the heart, usually secondary to myocardial infarction. (12 Dec 1998) |
| costophrenic septal lines | Fine peripheral septal lines. Synonym: costophrenic septal lines. (05 Mar 2000) |
| posterior 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) |
| posterior septal artery of nose | A branch of the sphenopalatine artery that supplies the nasal septum and accompanies the nasopalatine nerve. Synonym: arteria nasalis posterior septi. (05 Mar 2000) |
| precommissural septal area | A slender vertical whitish band immediately anterior to the lamina terminalis and anterior commissure; contrary to its name, it is not a cortical convolution but is the ventral continuation of the transparent septum. Synonym: area subcallosa, gyrus paraterminalis, gyrus subcallosus, pedunculus corporis callosi, corpus paraterminale, paraterminal body, paraterminal gyrus, peduncle of corpus callosum, precommissural septal area, subcallosal area, Zuckerkandl's convolution. (05 Mar 2000) |
| heart septal defects | Defects in the cardiac septa, resulting in abnormal communications between the opposite chambers of the heart. (12 Dec 1998) |
| heart septal defects, atrial | Defects in the septum between the atria of the heart, due to failure of fusion between either the septum secundum or the septum primum and the endocardial cushions. (12 Dec 1998) |
| heart septal defects, ventricular | Congenital defects in the septum between the cardiac ventricles, most often due to failure of the bulbar septum to completely close the interventricular foramen. (12 Dec 1998) |
| septal | Relating to a septum. (05 Mar 2000) |
| septal area | The region of the cerebral hemisphere that stretches as a thin sheet of brain tissue between the fornix bundle and the ventral surface of the corpus callosum, forming the medial wall of the lateral ventricle's frontal horn; it extends ventrally through the narrow interval between the anterior commissure and the rostrum of corpus collosum as the precommissural septum or subcallosal gyrus, which is continuous caudally with the preoptic area and hypothalamus, as well as more laterally with the innominate substance; its major functional connections are with the hippocampus and hypothalamus. (05 Mar 2000) |
| septal artery | <anatomy, artery> A branch of the superior labial artery that supplies the lower part of the nasal septum. (05 Mar 2000) |
| 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) |
