Found in the lining of the bladder to prevent urine from leaking into surrounding tissues. 2. Anchoring Junctions
They act as a diffusion barrier, preventing the leakage of fluid and solutes between cells (paracellular transport). cell junctions ppt download
Cell junctions are specialized protein complexes that provide physical connections between neighboring cells or between a cell and its extracellular matrix . These structures are vital for maintaining the integrity of tissues, regulating the movement of solutes, and facilitating intercellular communication. In epithelial tissues, they are often grouped into a "junctional complex" near the apical surface of the cell. Classification of Cell Junctions Found in the lining of the bladder to
Tight junctions (also known as zonula occludens ) form a continuous, impermeable seal around the apical end of cells. Classification of Cell Junctions Tight junctions (also known
Animal cell junctions are broadly categorized into three functional groups based on their primary roles: 1. Occluding (Tight) Junctions
