Intercellular junctions were discovered by Albert Schweigger-Seidel in the early 19th century. However, modern understanding and classification of various types of intercellular junctions have been developed through the work of multiple scientists over the years.
Intercellular joining refers to the process by which cells physically connect with each other, forming tight junctions, adherens junctions, desmosomes, or gap junctions. These junctions play a crucial role in maintaining tissue structure and integrity, as well as facilitating cell communication and signaling within multicellular organisms.
Cells in the human body are connected through a network of structures called intercellular junctions. These junctions allow cells to communicate, adhere to one another, and exchange molecules. There are different types of intercellular junctions, such as tight junctions, gap junctions, and desmosomes, that play specific roles in maintaining tissue structure and function.
All four tissue types—epithelial, connective, muscle, and nervous tissue—can have intercellular junctions, but they are most prominent in epithelial and cardiac muscle tissues. Epithelial tissues utilize tight junctions, desmosomes, and gap junctions to maintain structural integrity and facilitate communication. Cardiac muscle tissue also features intercalated discs, which contain gap junctions and desmosomes to synchronize heart contractions. In contrast, connective and nervous tissues typically have fewer intercellular junctions, focusing more on structural support and signal transmission, respectively.
Gap junctions are intercellular junctions that provide ionic and electrical continuity between adjacent cells. They consist of connexin proteins that form channels allowing for the passage of ions and small molecules between cells. This communication is important for coordinating cell activities and signaling within tissues.
An example of intercellular joining is the formation of tight junctions between epithelial cells. These junctions create a barrier that prevents the passage of molecules between cells, thus maintaining distinct environments on either side of the epithelium. Tight junctions play a crucial role in regulating the absorption of substances in organs like the intestines and the blood-brain barrier.

The intercellular junctions occurring within the stratum spinosum are referred to as desmosomes. Desmosomes are specialized cell structures that function to connect neighboring cells within epithelial tissues, providing strength and support.
Gap junctions are intercellular junctions that provide ionic and electrical continuity between adjacent cells. They consist of connexin proteins that form channels allowing for the passage of ions and small molecules between cells.

Within the multicellular organism tissues, a cell junction occurs. Animals have four kinds of intercellular junctions which are gap junction, desmosomes, adherens junction and tight junction,
