How Do You Spell SEPTUM TRANSVERSUM?

1. The septum transversum is a structure found in embryology and anatomy that refers to a horizontal partition or membrane that divides the developing body cavity into upper and lower regions. Derived from the mesoderm during early embryonic development, it plays a crucial role in organizing and separating various organs within the developing abdomen.

   In the developing embryo, the septum transversum originates near the level of the heart and extends toward the caudal or tail end. It helps create the diaphragm, a muscular structure that separates the thoracic and abdominal cavities. The septum transversum also gives rise to the central tendon of the diaphragm, providing support and attachment for the muscle fibers that contribute to respiration.

   Furthermore, the septum transversum serves as an essential component in the formation of other structures within the abdominal region. It contributes to the formation of the liver, connecting the liver bud to the anterior body wall and keeping it suspended within the abdominal cavity. It also assists in the development of the pericardium, the sac-like membrane that encloses the heart.

   Overall, the septum transversum plays a significant role in the embryonic development of various organs, particularly the diaphragm, liver, and pericardium. This partition acts as a vital reference point for spatial organization within the growing embryo, facilitating the proper positioning and functioning of these crucial structures as they continue to develop and mature.

2. (1) The projection into each ampulla of the semicircular canals of the thickened wall on which the nerves terminate; (2) the partition which forms in the embryo and divides the splanchnocoele into the abdominal and pericardial regions, becoming in mammals the diaphragm.
