A(n) propagates down an axon of the first neuron like a wave across the ocean until it reached a gap between neurons called a. the sudden change in membrane potential triggers the release of which diffuse across a and then another is generated on a dendrite of the second neuron.

The small molecule cyclic amp (camp) takes about 0.2 second to diffuse 10 μm, on average, in a cell. suppose that camp is produced near the plasma membrane on one end of the cell; how long will it take for this camp to diffuse through the cytosol and reach the opposite end of a very large cell, on average? assume that the cell is 200 μm in diameter.
