|
Membrane Junctions
|
D - Specializations of the Plasma membrane that are further subdivided into tight junctions, desmosomes, and gap junctions.

Tight junctions
|
D - Adjacent plasma membrane fuse tightly together like a zipper.
F - Impermeable junctions that bind cells together into leakproof sheets that prevent substances from passing through the extracellular space between cells m |

Desmosomes
|
D - buttonlike thickening of adjacent plasma membranes that are connected by fine protein filaments.
F - Prevent cells subjected to mechanical stress (I.e skin cell) from being pulled apart. |
|
|
Gap Junctions
|
D - Neighboring cells are connected by connexons (hollow cylinders composed of proteins that span the entire length of the abutting membranes)
F - Allows communication between cells (I.e heart, embryo) |
