septum

 [sep´tum] (L.)
1. a wall or partition dividing a body space or cavity. Some are membranous, some are osseous, and some are cartilaginous; each is named according to its location. See also septal defect. adj., adj sep´tal.
alveolar septum interalveolar septum.
atrial septum (septum atrio´rum cor´dis) interatrial septum.
atrioventricular septum the part of the membranous portion of the interventricular septum between the left ventricle and the right atrium.
deviated septum an injury or malformation of the nasal septum so that one part of the nasal cavity is smaller than the other; this is fairly common and seldom causes complications. Occasionally the deviation may handicap breathing, block the normal flow of mucus from the sinuses during a cold, or prevent proper drainage of infected sinuses. In some cases surgery (called partial or complete submucous resection) may be necessary to relieve the obstruction and reduce irritation and infection in the nose and sinuses.
interalveolar septum
1. one of the thin plates of bone separating the alveoli of the teeth in the mandible and maxilla. Called also interradicular septum.
2. one of the thin septa that separate adjacent pulmonary alveoli, containing connective tissue and the capillary network of the blood supply of the lung. Defs. 1 and 2 called also alveolar septum.
interatrial septum (septum interatria´le cor´dis) the partition separating the right and left atria of the heart; called also atrial septum.
interradicular septum interalveolar septum (def. 1).
interventricular septum (septum interventricula´re cor´dis) the partition separating the right and left ventricles of the heart; called also ventricular septum.
nasal septum a plate of bone and cartilage covered with mucous membrane that divides the nasal cavity.
septum lu´cidum septum pellucidum.
pellucid septum (septum pellu´cidum) the triangular double membrane separating the anterior horns of the lateral ventricles of the brain; called also septum lucidum.
septum pri´mum a septum in the embryonic heart, dividing the primitive atrium into right and left chambers. See also congenital heart defect.
rectovaginal septum the membranous partition between the rectum and vagina.

nasal septum

The thin, central partition that divides the interior of the nose into two passages. The septum consists of a thin plate of bone, behind, and a thin plate of cartilage in front. Both are covered with MUCOUS MEMBRANE. Deflection of the septum to one side (deviated septum) is common and usually harmless.
