Cell Junctions

Define Cell junctions

specialized structures which contrast adjacent cells therefore helping epithilial tissues

Tight Junction

Seal between cells & prevents things from going between cells like blood brain, barrier

Adherns Junction

Connection of actin filaments of neighbouring cells, function is to maintain shape and integrity of epithilial tissue layers

Desmosome

Strong connection between anchoring filaments to provide resisstance to mechanical stress like skin and heat

Gap junnction

Exists to allow for communication, areas that require for synchronised function = cardiac muscle

Hemidesmosome

Half of a desmosome that connects to the bottom half of the cell of the basement membrane
