Detailed explanation-1: -The neurotransmitters are transported across the very small distances between nerve cells, which are called chemical synapses. The small distance between nerve cells allows the signal to travel quickly; this enables an immediate response.

Detailed explanation-2: -One unique example of paracrine signaling is synaptic signaling, in which nerve cells transmit signals. This process is named for the synapse, the junction between two nerve cells where signal transmission occurs.

Detailed explanation-3: -Endocrine signaling is an example of long distance communication between hormone producing cells, tissues and glands and cells that express hormone receptor molecules.

Detailed explanation-4: -Neurons as an Example of Long-Distance Bioelectric Signaling Neurons control their membrane potential via ion pumps and channels, transmit these signals over very long distances via highly specialized axonal projections, and interface with receiving cells via gap junctions or targeted secretion.
