THE GALL BLADDER AND BILE DUCTS
|
|
| Location / position |
- Right hypochondrium
- Tip of the 9 th costal cartilage in the mid-clavicular line
- where the linear semilunaris meets the costal margin.
- Visceral surface of liver
- Along right edge of the quadrate lobe of the liver.
|
 |
| |
|
|
| Relations |
|
 |
 Superior surface is in contact with the liver.
Its inferior and fundus in contact with:
- Transverse colon
- Superior part of the duodenum
- Anterior abdominal wall.
The neck of the gall bladdes tapers towards the porta hepatis.
The epiploic foramen lies immediately to its left. |
| |
|
|
| Peritoneal relations |
|
- Covered on the posterior and inferior surfaces by peritoneum.
- Occasionally, the gall bladder is completely invested with peritoneum, and may be connected to the liver by a short mesentry.

| Blood supply |

 |
Arterial :
Cystic artery – commonly a branch of the right hepatic between hepatic duct and cystic duct. The origin and course of this artery is variable. It may arise from:
- Common hepatic
- Left hepatic
- Superior epigastric
- Left gastric
- Left hepatic
- Gastroduodenal
- Superior mesenteric
- Coeliac trunk
It commonly runs posterior to hepatic duct, but may run anterior . |
| |
|
|
| Veins : |
|
Those from the ducts and neck of gall bladder join veins which connect the
- Gastric
- Duodenal
- Pancreatic
- Portal vein
- Some go to the liver directly.
|
| |
|
|
Lymphatics
- Cystic node at the neck of the gall bladder.
- Node of epiploic foramen – hepatic nodes – coeliac lymph nodes
|
| |
|
|
Innervation
- Sensory innervation - phrenic nerve
- Sympathetic - coeliac plexus
- Parasympathetic - vagus
