Q

secreted by your glands, flow through the bloodstream; are chemical messengers that must bind to a receptor in order to send their signal. However, unlike neurotransmitters, which are released in close proximity to cells with their receptors, these are secreted into the bloodstream and travel throughout the body, affecting any cells that contain receptors for them. Thus, whereas neurotransmitters’ effects are localized, the effects of these are widespread. Also, they are slower to take effect, and tend to be longer lasting.

Q

descends from the hypothalamus at the base of the brain, and acts in close association with it. This is often referred to as the “master gland” because its messenger hormones control all the other glands in the endocrine system, although it mostly carries out instructions from the hypothalamus. In addition to messenger hormones, this also secretes growth hormones, endorphins for pain relief, and a number of key hormones that regulate fluid levels in the body.
