mesentery

A mesentery (Latin Serosa intermedia ) is a peritoneum fold on an internal organ, which usually functions as a hanging strap and connects the organ to the abdominal wall. It is a serosa double lamella that runs between the organ coating ( peritoneum viscerale ) and the wall lining ( peritoneum parietale ).

According to the organ involvement, the mesentery is divided:

• Mesentery is the generic term for the hanging strap of the intestine. In human and veterinary anatomy, the term is also used restrictively for the mesentery of the small intestine , more precisely the jejunum ( mesojejunum ) and the ileum ( mesoileum ).
• Mesocolon : the hanging strap of the large intestine
• Mesogastrium : the embryonic suspension apparatus of the stomach , divided into anterior and posterior mesogastrium (in animal anatomy, mesogastrium dorsale and ventral ), after birth as omentum greater and omentum minus .
• Mesovarium : the hanging apparatus of the ovary
• Mesosalpinx : those of the fallopian tube
• Mesometrium : the peritoneum duplication on both sides of the uterus

The peritoneum duplicates around the internal female genital organs - mesovar, mesosalpinx and mesometrium - are also summarized as the ligamentum latum uteri . The peritoneum coating of the testicles and epididymis is special in that it loses its physiological connection with the body cavity when the testes descend .

Colloquially, the word gekröse is also used synonymously for the term innards , which today is usually negatively or disgustingly connoted.
