Anatomy
|
Macroscopic Mucosal features:
|
Epithelium
- Columnar epithelium with microvilli (absorptive epithelium)
- Epithelium lining the biliary system does not contain mucus-producing cells (few located in neck of gall bladder)
- Basement membrane (not basal lamina which forms part of basement membrane and only visible by EM)
Lamina Propria
- connective tissue
- collagen fibers and fibroblasts
- fenestrated capillaries and venules
- lymphocytes and plasma cells
Smooth Muscle Layer
- random orientation of smooth muscle cells (fibers)
- muscularis propria (or fibromuscular coat) PMID 21074688
- not like the rest of GIT smooth muscle organisation, which is divided into muscularis mucosa (inside submucosa), muscularis externa (circular and longitudinal)
- various terminology used for this layer in different sources
Serosa/Adventitia
- Dense connective tissue layer covered with visceral mesothelium epithelial layer
- Adventitia - where it is attached to the liver
- Serosa - where it is free in the peritoneum
- Large blood vessels (arteries, veins)
- Obvious lymphatic vessels
- Autonomic nerve bundles
- Adipose tissue
