what is the cell junction marked as circle ?
Correct Answer: zona adherens
Description: image shows : zona occludens : tight junctions in intestine and renal tubular cells ell Junctions Types Tight Junctions (Occluding Junctions) Seal adjacent epithelial cells together prevent passage of molecules, membrane-bound lipids and proteins Gap Junctions (Communicating Junctions)= Allow adjacent cell communication; pass ions & small molecules between cytoplasms Focal Adhesions & Hemidesmosomes (Anchoring Junctions, Actin & Intermediate Filament Attachment Sites)= Form around integrin-mediated cell--ECM contacts Focal adhesions connect integrins to actin filaments Hemidesmosomes connect integrins to intermediate filaments Adherens Junctions & Desmosomes (Anchoring Junctions, Actin & Intermediate Filament Attachment Sites) Form around cadherin-mediated cell--cell contacts Adherens junctions connect cadherins to actin filaments Desmosomes connect cadherins to intermediate filaments ref : bd chaurasia/guyton and hall
