transversum Definition på svenska

Examples of transversum

• Besides of signals from the septum transversum mesenchyme, fibroblast growth factor from the developing heart also contribute to hepatic competence, along with retinoic acid emanating from the lateral plate mesoderm.

• The surrounding mesocardium degenerates to leave the primitive heart attached only by its arterial and venous ends, which are anatomically fixed to the pharyngeal arches and the septum transversum, respectively.

• The septum transversum, the primitive central tendon of the diaphragm, originates at the rostral pole of the embryo and is relocated during longitudinal folding to the ventral thoracic region.

• During subsequent weeks the dorsal end of the embryo grows much faster than its ventral counterpart resulting in an "apparent descent" of the ventrally located septum transversum.

• After migration of hepatoblasts into the septum transversum mesenchyme, the hepatic architecture begins to be established, with liver sinusoids and bile canaliculi appearing.

• Though not derived from the septum transversum, development of the liver is highly dependent upon signals originating here.

• Normally, the pleuroperitoneal membranes fuse with the septum transversum, oesophageal mesentery and body wall by seven weeks of gestation.
