Septum transversum - Wikipedia
The septum transversum is a thick mass of cranial mesenchyme, formed in the embryo, that gives rise to parts of the thoracic diaphragm and the ventral mesentery of the foregut in the developed human being and other mammals.
Septum Transversum - an overview | ScienceDirect Topics
Septum transversum refers to a sheet of mesoderm that appears rostral to the developing heart and forms the central tendon of the diaphragm. AI generated definition based on: Embryology (Second Edition) , 2009
Septum Transversum - an overview | ScienceDirect Topics
The diaphragm develops during the 4th through 12th weeks of intrauterine life from the septum transversum, pleuroperitoneal fold (PPF), somites, and dorsal esophageal mesentery. The septum transversum is the first structure to be formed during embryogenesis of the diaphragm.

during weeks 5-6, the septum transversum is moving through the regions between C3, 4, and 5 and receives myoblasts that will eventually develop into the skeletal muscle of the diaphragm.
Development of the diaphragm, a skeletal muscle essential for …
Embryonically, the diaphragm derives from three sources: the septum transversum, the pleuroperitoneal folds, and the somites. Currently, it is unclear whether the septum and folds are only transient embryonic structures or whether they contribute to tissues of the mature diaphragm.

4 天之前 · Initially, the transverse septum (septum transversum) arises at an embryonic junctional site. The junctional region externally is where the ectoderm of the amnion meets the endoderm of the yolk sac. The junctional region internally is where the foregut meets the Midgut.

PLEUROPERITONEAL MEMBRANES fuse with the dorsal mesentery of the esophagus and with the dorsal part of the septum transversum to complete the partition between the thoracic and abdominopelvic cavities to form the primitive diaphragm. They represent only a small portion of the final adult structure.

2023年8月7日 · Septum transversum: Septum transversum that lied cranial to the pericardial cavity also comes ventrally but lies caudal to the pericardial cavity. Septum transversum grows posteriorly but stops at the foregut, forming: Primitive diaphragm between pericardial cavity and periotneal cavity (divides pericardio-peritoneal canal)
Septum Transversum - Cellular Development, Function
The septum transversum (ST) forms from an aggregation of mesenchyme tissue that develops within the caudal part of ventral mesentery of the foregut. This compartment gives rise to the partition of the coelom, part of the diaphragm, stomach and duodenum. ST separates heart from the developing liver.
Septum Transversum became caudal (rather than cranial) to the developing heart tissue. Primitive Streak was cranial to the cloacal membrane. Now it is caudal. The connecting stalk is pushed ventral-medially and becomes the umbilical cord. Primitive Gut was formed from the dorsal regions of the yolk sac.
