Concluding Discussions and Propositionsranes come close together, reducing the intercellular space to 2–4 nm. Structures known as connexons lie in clusters within each membrane, uniting in pairs across the gap. Since each connexon is annular, enclosing a channel, the junction appears to provide a direct, low-resistance pathway between ce

In freeze-fracture replicas viewed by electron microscopy, gap junctions are composed of tightly packed clusters of particles (Kreutziger, 1968). Each particle in a gap junction pr

Gustave de Beaumont,Alexis de TocquevilleCell-to-cell coupling through low-resistance junctions represents a very old mechanism of intercellular communication. In sponges and medusae, for instance, without nervous tissue, the epithelia receive external stimuli and convert them into electrical pulses that are conducted in all directions through low-resistance junctions (Mackie, 1964).
