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.
Connective tissue contains jellylike intercellular material called the extracellular matrix, which provides support and connects cells together. Examples of connective tissue include cartilage, bone, and adipose tissue.
Adjacent cells at a gap junction are connected by proteins called connexins. These proteins assemble to form connexons, which are hexameric structures that create channels between cells. These channels allow for the direct transfer of ions and small molecules, facilitating intercellular communication and coordination of cellular activities.
Acetylcholine is the chemical that transmits signals across the neuromuscular junction. It binds to receptors on the muscle cell membrane, leading to muscle contraction.
Extracelluar Matrix
Gap junctions are the intercellular junctions that facilitate the rapid movement of small molecules or ions between adjacent animal cells. These specialized structures consist of protein channels called connexons that connect the cytoplasm of one cell to that of another, allowing for direct communication and coordination of cellular activities. This connectivity is crucial for processes such as electrical signaling in cardiac and smooth muscle tissues.
The junction between a motor neruon's axon and the muscle cell membrane is called a neuromuscular junction or a myoneuraljunction?
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
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.
Connective tissue contains jellylike intercellular material called the extracellular matrix, which provides support and connects cells together. Examples of connective tissue include cartilage, bone, and adipose tissue.

Gap junction
Extracelluar Matrix
The two bundles initially are together at a junction called the bundle of His.
The association site of a nerve and a muscle is called a neuromuscular junction. At this specialized synapse, motor neurons release neurotransmitters, such as acetylcholine, which bind to receptors on the muscle fiber's membrane, leading to muscle contraction. This junction is crucial for the communication between the nervous system and muscle tissue, enabling voluntary movement.
