4.20 Three types of cell junctions are found in animal tissues

Gap Junctions

channels that allow small molecules to flow through protein-lined pores between cells aka communicating junction

Anchoring Junction

A muscle tear injury would probably involve the rupture of which type of cell junciton

Gap Junction

Which junction allow the flow of ions through in the cells of heart muscle to coordinate their contractions. Common in Embryos which is important for devolpment

Anchoring Junctions

fasten cells together into strong sheets...-common in tissues subject to stretching or mechanical stress like skin and muscles Intermediate filaments made of STURDY Proteins anchor these junctions in the cytoplasm

Tight junctions

the plasma membranes of neighboring cells are very tightly pressed against each other, bound together by proteins---Prevents leakage of fluid across a layer of cells
