Cisterna chyli
The cisterna chyli (from cisterna "cistern", chylus "lymph") or lumbar cistern is a collection space for lymph in the belly of the first two lumbar vertebrae .
location
The lymph vessels of the abdomen, pelvis and legs (hind limbs) flow into this thin-walled cistern . The lumbar cistern is part of the lymphatic system .
Inflows to the lumbar cistern are:
- Truncus lumbalis ("lumbar trunk"): paired, conducts the lymph from the pelvis and lower (rear) extremity
- Truncus intestinalis , in animal anatomy Truncus visceralis ("intestinal trunk "): unpaired, collects the lymph from the liver , stomach , spleen and intestines
The union of the visceral trunk to the visceral trunk does not occur in all animal species. In horses , the celiac trunk (liver, stomach, spleen) and intestinal trunk (intestine) are two tributaries from the intestines to the lumbar cistern.
The only drainage of the cisterna chyli is the thoracic duct (breast duct), which finally opens into the left vein angle in the upper mediastinum between the subclavian vein and internal jugular vein.
First describer
The French anatomist Jean Pecquet (1622–1674) is considered the first to describe it .
