Detailed explanation-1: -This method of communication allows cells to coordinate movement and activity with their neighbors. An example of this is called synaptic signaling. That’s when signaling occurs across the tiny gap between two neurons.

Detailed explanation-2: -Cells typically communicate using chemical signals. These chemical signals, which are proteins or other molecules produced by a sending cell, are often secreted from the cell and released into the extracellular space. There, they can float – like messages in a bottle – over to neighboring cells.

Detailed explanation-3: -Answer and Explanation: Gap junctions are the specialized cell communication channels between adjacent or neighboring cells. The function of the gap junctions is to directly connect the cytoplasm of two cells. These channel allows the movement of molecules, electrical impulses, and ions between the connected cells.

Detailed explanation-4: -There are four categories of chemical signaling found in multicellular organisms: paracrine signaling, endocrine signaling, autocrine signaling, and direct signaling across gap junctions.
