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.

What junction in plant cells connects the cytoplasm of living cells?
Plasmodesmata are junctions in plant cells that connect the cytoplasm of living cells. They are microscopic channels that pass through the cell walls, allowing for communication and transport of materials between adjacent plant cells.
A junction that is a protein channel linking the cytoplasms of adjacent cells is called?
A junction that is a protein channel linking the cytoplasms of adjacent cells is called a gap junction. This structure allows for direct communication and sharing of ions and small molecules between neighboring cells.
Which cell junction has a linker proteins spanning the intracellular space?
Desmosomes have linker proteins known as desmoplakins that span the intracellular space and help to connect intermediate filaments. Desmosomes provide strong adhesion between adjacent cells, especially in tissues that experience mechanical stress, such as the skin and heart muscle.
What is the Electrical synapse between adjacent myocardial cells are called?
Gap junction
Which cell junction is not illustrated and what is it's function?
Desmosomes - anchoring junctions that hold adjacent cells together

One of the major transmembrane proteins in a “tight junction” is?
One of the major transmembrane proteins in a tight junction is occludin. It plays a key role in sealing the intercellular space between adjacent cells to maintain the integrity and selective permeability of the epithelial or endothelial barrier.
Which cell junction has a linker proteins spanning the intracellular space?
Desmosomes have linker proteins known as desmoplakins that span the intracellular space and help to connect intermediate filaments. Desmosomes provide strong adhesion between adjacent cells, especially in tissues that experience mechanical stress, such as the skin and heart muscle.
Which is a belt-like intercellular junction?
A belt-like intercellular junction is known as a zonula adherens, or adherens junction. It encircles the cells and provides strong mechanical adhesion between adjacent epithelial cells, facilitating tissue integrity and communication. This junction is primarily composed of cadherin proteins and is linked to the actin cytoskeleton, playing a crucial role in maintaining the structural organization of tissues.

Desmosomes - anchoring junctions that hold adjacent cells together
Which type of membrane junction is an example of a tight junction?
Junctions among epithelial cells lining the digestive tract.
What junction allows the tissue to stretch and bend in epithelium?
Desmosomes are junctions that allow epithelial tissues to stretch and bend while providing structural support. They are composed of proteins that link adjacent cells and help maintain the integrity of the tissue.
What is the channel between animal cells?
The channel between animal cells is called a gap junction. Gap junctions allow for the direct exchange of ions and small molecules between adjacent cells, facilitating communication and coordination within tissues.
What type of cellular junction that forms when a channel is formed between two adjacent plasma membrane?
A gap junction forms when a channel is created between two adjacent plasma membranes. This type of cellular junction allows for direct communication and passage of small molecules between the two cells.
What type of intercellular junction stops materials from crossing an eithelium between cells?
Tight junctions form a seal between adjacent epithelial cells, preventing the passage of materials between cells. They help maintain the integrity and barrier function of the epithelium.
