In vertebrates, there are three major types of cell junction:
1. Adherens junctions, desmosomes and hemidesmosomes (anchoring junctions.)
2. Gap junctions (communicating junction)
3. Tight junctions (occluding junctions)
Your question most likely is for the tight junction but more information in the question would be helpful.
Extracelluar Matrix
a gap junction
structural model of plasma membrane is called the selectively permeable membrane Structural model of the plasma membrane is called Fluid Mosaic Model.
The junction of the parietal, temporal and occipital association areas is called the general interpretative area
neuromuscular junction
The junction between a motor neruon's axon and the muscle cell membrane is called a neuromuscular junction or a myoneuraljunction?
Animal cells are mostly bound together by what are known as intercellular junctions. There are three types of cell junctions: anchoring junctions, tight junctions and gap junctions. Of these, anchoring junctions, which include adherens junction, desmosomes and hemidesmosomes, help bind the animal cells together, in an extracellular matrix.
Intercellular connections that lock cells togther are desmosomes. Desmosomes appear as thickened patches in the cell membrane region between two cells. They contain specialized proteins that increase the rigidity of tissues.
Cardiocytes are joined together by junctions called intercalated discs.
neuromuscular junction or myoneural junction
A animals cells are connected together by a thing called junctions . A junction connects either the cytoplasm , membrane or even cell itself together to form a in penetrable cell wall of fluid .
Gap junction
Extracelluar Matrix
The two bundles initially are together at a junction called the bundle of His.
It is often called the cell membrane because it is made up of phospholipid bilayers. It is also often called the plasma membrane. Each phospholipid joins together at the hydrophilic head, leaving the hydrophobic tail on the inside, and forming a bilayer.
Its called "the fluid mosaic model" of the cell membrane. This describes the clumping together of phospholipids to form rafts and their motion (along with single phospholipids) throughout the membrane.
It's literally called a junction.
