A specialized area of apposed plasma membranes containing connexons, proteins that bridge the extracellular space and that allow the cytoplasm of one cell to communicate with that of the other cell.
A site of electrical connection between two cells, where gap junction channels bridge the gap between the insides of the two cells and allow small molecules such as ions to cross directly from one cell to the other.
a cellular junction which allows the two-way spread of action potentials from one cell to the next.
A specific type of junction between two cells.
Protein channels linking cytoplasm of adjacent cells that allows ions and small molecules to flow between cytopla´Â of the cells.
Communicating cell-cell junction that allows ions and small molecules to pass from the cytoplasm of one cell to the cytoplasm of the next.
A 2.7-nanometer gap between plasma membranes of two animal cells, spanned by protein channels. Gap junctions allow chemical substances or electrical signals to pass from cell to cell.
A structure within the intercalated disks located at the junctions of the branches of myocardial cells, permitting very rapid conduction of electrical impulses from one cell to another.
Channel formed by proteins that allows ions and other molecules to pass between adjacent cells
a cell-cell junction that allows the direct transfer of small cytosolic components between adjacent cells
a connection between cells, which allows materials from one cell to be passed to a neighboring cell
a junction between certain animal/plant cell -types that allows different molecule s and ion s to pass freely between cells
a junction between two cells, via special protein channels, that connect the cytoplasm of the cells
a transmembrane pathway of low electrical resistance that connects the cytoplasm of adjacent cells
A connection between two cells bridged by connexons.
A place where the cell membranes of two cells come in direct contact, allowing electrical potentials to be conducted directly from one to another. Contrast synapse.
Epithelial junction which allows for the electrical coupling of cells
A gap junction or nexus is a junction between certain animal cell-types that allows different molecules and ions to pass freely between cells. The junction connects the cytoplasm of cells. One Gap junction is composed of two connexons (or hemichannels) which connect across the intercellular space.
