Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is a type of long-distance signaling?
A
Endocrine signaling
B
Paracrine signaling
C
Synaptic signaling
Explanation: 

Detailed explanation-1: -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-2: -There are four categories of chemical signaling found in multicellular organisms: paracrine signaling, endocrine signaling, autocrine signaling, and direct signaling across gap junctions (Figure 9.2).

Detailed explanation-3: -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-4: -Long distance signaling is a type of cell communication whereby the signaling molecules act on a target cell that is far from the signaling cell. On the other hand, local signaling is when cells that are close to one another communicate using signals such as paracrine signals.

Detailed explanation-5: -Answer and Explanation: Insulin signaling is an example of endocrine signaling. Insulin signaling is an important form of cell signaling for the maintenance of homeostatic blood sugar levels.
