Detailed explanation-1: -For example, epinephrine functions both as a neurotransmitter and as a hormone produced by the adrenal gland to signal glycogen breakdown in muscle cells.

Detailed explanation-2: -In long-distance endocrine signaling, signals are produced by specialized cells and released into the bloodstream, which carries them to target cells in distant parts of the body. Signals that are produced in one part of the body and travel through the circulation to reach far-away targets are known as hormones.

Detailed explanation-3: -Answer and Explanation: Yes, endocrine signaling is an example of long-distance signaling. Specialized cells, tissues, glands, and organs use the circulatory system to send the hormones they produce in order to target cells in other parts of the body. It produces a slow and long-lasting response in these target cells.

Detailed explanation-4: -Neuronal signaling is perhaps the best-studied example of long-distance biophysical signaling.
