Study Notes
Cell Junctions
- Fasciae adherentes, a type of anchoring junction, form a spot-like junction similar to Zonula adherens.
- The main function of Tight junctions in the columnar cells of the intestine is to prevent the passage of molecules between cells.
- Celiac disease is caused by an immune response to gluten.
- Desmosomes (Macula adherens) contain transmembrane protein linkers such as cadherins.
- Tight junctions in the endothelium of blood capillaries in the brain prevent paracellular transport.
- The function of Hemidesmosomes is to attach epithelial cells to the underlying basement membrane.
- Basal infoldings are found in the kidney and are specialized for reabsorption and ion transport.
- Gap junctions (nexus) are composed of a cluster of connexons that form a channel.
- Fibroblasts mainly synthesize collagen fibers.
- The function of occluding (tight) junctions is to prevent the passage of molecules between cells.
- Cadherin sites are located on the surface of cells.
- The main function of intermediate filaments in hemidesmosomes is to provide mechanical strength.
- Gap junctions allow for direct communication between cells through the exchange of ions and small molecules.
- C.T. stands for Connective Tissue in the context of the text.

Description
Prepare for your histology exam by revising topics related to epithelial cell surfaces, including lateral surface junctions, basement membrane specialization, and medical applications such as celiac disease. Understand the impact of celiac disease on intestinal inflammation and the decrease of microvilli of absorptive cells.
