Gall bladder (vesica fellea) has a saccular shape characteristic dark green color and is located on the inner surface of the liver to the gallbladder fossa (fossa vesicae felleae), while connecting with the fibrous sheath liver through the loose tissue. Its length is 8-14 cm
The gall bladder is from the bottom (fundus vesicae felleae), which is the widest part of the body (corpus vesicae felleae), which is the middle part, and the narrowest part - the neck (collum vesicae felleae), which departs from the cystic duct. The bottom of the gall bladder is sent to the lower regions of the liver, and cervix - the gate of the liver. In the transition of the body is formed in the neck bend.
Serosa covers the free surface of the gall bladder. Under it is podseroznaya basis (tela subserosa vesicae), which is a layer of loose connective tissue, which is considerably thicker at the top not covered by the peritoneum of the gallbladder wall.
Muscle membrane of the gallbladder is formed by a circular layer of smooth muscle, including bundles of longitudinally and obliquely situated fibers. The greatest thickness of the muscular layer reaches the neck area.
The mucous membrane of the gall bladder is lined with single-row cylindrical epithelium. It generates multiple small folds (plicae tunicae mucosae vesicae felleae), so has the form of a network. In the area of ??the neck formed obliquely placed spiral folds (plicae spirales). In the area of ??the body and the neck is submucosa, which are cancer.
