The transmission of a signal through the nervous system can also be considered an example of long-distance signaling. Local signaling in plants is not well understood. Because of their cell walls, plants must have different mechanisms from animals. Plants and animals use hormones for long-distance signaling. In animals, specialized endocrine cells release hormones into the circulatory system, by which they travel to target cells in other parts of the body. Plant hormones, called growth regulators, may travel in vessels but more often travel from cell to cell or move through air by diffusion.
By Jennifer McDowall. Link to the structural features of acetylcholine receptors. The nervous system communicates with the body by sending electrical impulses from the central nervous system (CNS) through long nerves cells to the peripheral nervous system (PNS), muscles and glands.For this to work, neighbouring nerve cells must be able to convey these electrical signals between them.he nervous system communicates with the body by sending electrical impulses from the central nervous system (CNS) through long nerves cells to the peripheral nervous system (PNS), muscles and glands.
