Septum transversum
Septum Transversum
The Septum Transversum (pronunciation: sep-tum trans-ver-sum) is an essential structure in embryonic development, which later forms several components of the thoracic and abdominal cavities.
Etymology
The term "Septum Transversum" originates from Latin, where "Septum" means a partition or wall, and "Transversum" refers to something lying or extending across or in a cross direction.
Definition
The Septum Transversum is an embryonic structure that forms during the fourth week of human development. It is initially positioned at the cervical level and subsequently descends to the thoracic and upper abdominal regions. This structure eventually gives rise to the central tendon of the diaphragm and the ventral mesentery of the foregut, which includes the liver, gallbladder, and lesser omentum.
Development
The Septum Transversum develops from the mesoderm, one of the three primary germ layers in the very early embryo. The mesoderm itself originates from the gastrula during the process of gastrulation.
