Oxytocin and endorphin.
Hormones. The endocrine system consists of various glands that work together to secrete compounds into the blood known as "hormones". These hormones act in various ways on various tissues, controlling metabolism, neurological function, etc. Hope this helps. -Cheers P.S.

This system is a great example of how hormones act "trophically" on other hormones to initiate physiological responses.

Target cells respond to hormones because they have specific receptors for the hormone on their cell membrane or inside the cell. These receptors enable the hormone to bind and initiate a cellular response. Other cells that do not have the specific receptors for that hormone are unaffected because they cannot bind to the hormone or activate the necessary signaling pathways.
The council is prepared to initiate our latest initiate. "Initiate sequence!", shouted the Mission Commander.
