GENERAL HISTOLOGY

Detailed explanation-1: -Adherens junctions. (A) Adherens junctions, in the form of adhesion belts, between epithelial cells in the small intestine. The beltlike junction encircles each of the interacting cells.

Detailed explanation-2: -Tight junctions are found between most cells of the digestive tract. This type of cell junction prevents movement of material between cells, requiring it to actually move into cells via diffusion or active transport in order to pass through tissue.

Detailed explanation-3: -Tight junctions (TJs) play an important role in intestinal barrier function. TJs in intestinal epithelial cells are composed of different junctional molecules, such as claudin and occludin, and regulate the paracellular permeability of water, ions, and macromolecules in adjacent cells.

Detailed explanation-4: -Adjacent intestinal epithelia form tight junctions (TJs) that are essential to the function of the physical intestinal barrier, regulating the paracellular movement of various substances including ions, solutes, and water across the intestinal epithelium.

Detailed explanation-5: -Tight junctions, or zonula occludens (ZO), are characteristic of epithelial and endothelial cells (Figure 1). Located at the border between apical and lateral membranes, tight junctions regulate the passage of proteins and liquids across the cell monolayer.
