Development of the suspensory ligament of the ovary
Encyclopedia
The prenatal development of the suspensory ligament of the ovary
is a part of the development of the reproductive system
.
The suspensory ligament originates from the mesonephros
, which, in turn, originates from the Wolffian duct
:
The mesonephros evolves from the Wolffian duct, and this, in turn, by the fifth or sixth week, forms an elongated spindle-shaped fold. However, it should not be confused with the urogenital fold. This fold projects into the abdominal cavity
at the side of the dorsal mesentery
, reaching from the septum transversum
in front to the fifth lumbar segment
behind. It gives rise to e.g. the suspensory ligament of the ovary
in women.

Mesonephros
The mesonephros is one of three excretory organs that develop in vertebrates. It serves as the main excretory organ of aquatic vertebrates and as a temporary kidney in reptiles, birds, and mammals. The mesonephros is included in the Wolffian body after Caspar Friedrich Wolff who described it in 1759...

Abdominal cavity
The abdominal cavity is the body cavity of the human body that holds the bulk of the viscera. It is located below the thoracic cavity, and above the pelvic cavity. Its dome-shaped roof is the thoracic diaphragm , and its oblique floor is the pelvic inlet...

Dorsal mesentery
The portion of mesentery attached to the greater curvature of the stomach is named the dorsal mesentery , and the part which suspends the colon is termed the mesocolon....

Septum transversum
The septum transversum is a thick mass of cranial mesenchyme that gives rise to parts of the thoracic diaphragm and the ventral mesentery of the foregut in the developed human being.- Origins :...

Lumbar vertebrae
The lumbar vertebrae are the largest segments of the movable part of the vertebral column, and are characterized by the absence of the foramen transversarium within the transverse process, and by the absence of facets on the sides of the body...

Ovary
The ovary is an ovum-producing reproductive organ, often found in pairs as part of the vertebrate female reproductive system. Ovaries in anatomically female individuals are analogous to testes in anatomically male individuals, in that they are both gonads and endocrine glands.-Human anatomy:Ovaries...
