Expert Solution
Step 1: Answer 1

Gap junctions are involved in:

c) neural signaling.

Gap junctions are specialized intercellular channels that allow for direct communication and the exchange of ions and small molecules between adjacent cells. They play a crucial role in the coordination and synchronization of electrical and chemical signals in neural tissues, enabling rapid cell-to-cell communication in the nervous system. Therefore, they are primarily associated with neural signaling.
