| spiral bulbar septum | See: spiral septum. (05 Mar 2000) |
| spiral septum | A septum dividing the embryonic bulbus cordis into pulmonary and aortic outflow tracts from the developing heart; the distal spiral septum is derived from the right and left endocardial cushions and so separates the pulmonary and aortic orifices; the proximal spiral septum is the portion of the septum that is incorporated into the membranous part of the interventricular septum. (05 Mar 2000) |
| nasal septum | The dividing wall that runs down the middle of the nose so that there are normally two sides to the nose, each ending in a nostril. (12 Dec 1998) |
| depressor muscle of septum | <anatomy> A vertical fasciculus from the orbicularis oris musculus passing upward along the median line of the upper lip, and inserted into the cartilaginous septum of the nose; action, depresses septum; nerve supply, facial. Synonym: musculus depressor septi, depressor muscle of septum. (05 Mar 2000) |
| distal spiral septum | See: spiral septum. (05 Mar 2000) |
| division septum | <cell biology> The cell wall that forms between daughter cells at the end of mitosis in plant cells or just before separation in bacteria. (18 Nov 1997) |
| interalveolar septum | 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) |

| interlobular septum | The connective tissue between pulmonary lobules, usually containing a vein and lymphatics; seen radiographically when thickened as a Kerley B line. (05 Mar 2000) |
| intermediate cervical septum | A thin septum composed of glia fibre and leptomeningeal connective tissue in the cervical spinal cord marking the border between the gracile fasciculi and cuneatus of the dorsal funiculus. Synonym: septum cervicale intermedium. (05 Mar 2000) |
| intermuscular septum | <anatomy> A term applied to aponeurotic sheets separating various muscles of the limbs; these are anterior and posterior crural, lateral and medial femoral, lateral and medial humeral. Synonym: septum intermusculare. (05 Mar 2000) |
| interpulmonary septum | <anatomy> The space in the thoracic cavity behind the sternum and in between the two pleural sacs (containing the lungs). (27 Sep 1997) |
| interventricular septum | The stout wall separating the lower chambers (the ventricles) of the heart fromone another. A hole in the interventricular septum is termed a ventricular septal defect (vsd). (12 Dec 1998) |
