In humans there are two main systems for carrying messages from one part of the body to another: the nervous system and the blood.

Nerve cells (neurons) carry rapid impulses to precise locations. Every time a muscle contracts it is the result of a message arriving from a nerve cell; nerves stimulate some glands, too, for example the sweat glands in the skin.

The blood circulates continuously, and in it will be any hormones that have been secreted by endocrine(hormone-producing) glands. The message, in the form of the hormone, travels much more slowly than a nerve impulse, but the effect is much longer-lasting.

Apart from endocrine messaging, there are two other, more local, systems:

* paracrine: this system of signaling involves compounds being secreted by a cell and traveling a short distance to exert an effect on other cells nearby. A good example of this is the release of neurotransmitters (such as acetylcholine) to bridge the gap (synapse) between two neurons. * autocrine: this term refers to the release by a cell of a compound that has an effect on that same cell (hence "auto-"). The signal compound may leave the cell and stimulate a receptor embedded in the cell membrane, as if it were a chemical from another cell, or it may remain within the cell, simply carrying a message from one part of the cell to another.
