Location. Gap junctions are found in many places throughout the body. This includes epithelia, which are the coverings of body surfaces, as well as nerves, cardiac (heart) muscle, and smooth muscle (such as that of the intestines). Their primary role is to coordinate the activity of adjacent cells.

Where are gap junctions found quizlet?

Where are gap junctions found? They are found where the flow of ions between cells would allow for the spread of electrical activity, such as in cardiac muscle, coordinated activities such as beating of the cilia, or in neurons of the brain.

Where are gap junctions found in CNS?

In the adult CNS, neurons are coupled via gap junctions mainly composed of Cx36 [34] and Cx45 [40] in the cortex and hippocampus. These neuronal gap junctions play an important role in forming electrical synapses [41], [42].
