The pineal runs our Œbody clocks', and it produces melatonin; the hormone that may prove to be the biggest medical discovery since penicilin, and the key to controlling the aging process. The pineal gland controls such functions as our sleeping cycle and the change of body temperature

    The soft tissue the adult pineal gland contains more fluoride than any other soft tissue or gland in the human body. Dr. Luke summarized their findings on fluoride buildup in humans: “In conclusion, the human pineal gland contains the highest concentration of fluoride in the body.

The result strengthens

    Circadian rhythm is the internal body clock that controls psychological and biological processes in a 24-hour cycle. Circadian is the Latin word meaning “about 24 hours”. Circadian rhythms are triggered by cues that signal light and darkness (such as sunrise and sunset) as well as other visual cues (like clocks and television programs) The circadian clock in humans is found in the suprachiasmatic nucleus (SCN), which is a cluster of cells located in the hypothalamus (a region inside the brain) that

    endocrine system is a collaboration of all the glands in the human body and all the hormones produced by those glands1. The glands are controlled by the stimulation of the human nervous system including the chemical receptors in the blood and the hormones produced by other glands. By regulating and controlling the hormone levels in the body the endocrine system controls homeostasis in the body1. The gland system can be divided into two types. Exocrine glands release secretions outside of the bloodstream

    fatty acids composed the plasma membrane. Steroid hormones are testosterone, estrogen and cortisol. Testosterone and estrogen are important regulators of reproductive function, secreted by the testes and the ovaries. Cortisol released by the adrenal gland due to stress and lowered levels of blood glucocorticoids is involved in stimulating glucose synthesis, anti-stress and anti-inflammatory processes. They can pass through the plasma membrane because they are lipid

    partially comparable to that in fish. The bill of the platypus, Ornithorhynchus anatinus, and the beaks of the echidnas, Tachyglossus aculeatus and Zaglossus bruijni, all contain three types of receptors: push-rod mechanoreceptors, serous gland electroreceptors, and mucous gland electroreceptors. The information collected by these receptors is sent to the somatosensory cortex. The platypus, whose electroreceptive system is more complex than that of the echidna, uses electroreception to capture prey and is
