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.
Examples include autocrine, where the cell signals to itself, and paracrine, where a cell signals to a nearby neighbour. However, when cells need to communicate a message over a long distance, they can use the endocrine system. Endocrine signalling uses chemicals called hormones to send messages throughout the body.The hormones are released from the cell into the bloodstream and can travel around the entire body.here are many types of hormones-the chemicals which are responsible for endocrine signalling. Like most signalling pathways, hormones will bind to receptors on specific cells. This will produce the desired response within the cell.
