Different conditions of the thyroid gland mostly fall into these three categories:
Hypothyroidism: This is the under-functioning of the thyroid.
Hyperthyroidism: This is the over-functioning of the thyroid.
Euthyroid: This refers to there being normal functioning of the thyroid.
The thyroid gland is part of the endocrine (gland) system in the body. The endocrine system is useful for doing things like making adrenalin, insulin, hormones, and many other important secretions. The thyroid gland makes thyroid hormones, and four pockets of parathyroid glands within it make parathormone (parathyroid hormone), which affects the balance of calcium for our bones. Removing the entire thyroid gland will also remove the parathyroid glands, a surgical caveat that became apparent as soon as thyroid surgery was developed.
The thyroid itself is a butterfly-shaped gland that covers the trachea (windpipe) below the Adam’s apple. Its main ...
The human pineal gland manufactures the original sleep aid, melatonin (derived from serotonin), to put us into sleep. Although the pineal gland and its melatonin do not create our circadian rhythm, they act on it by increasing activity and levels, respectively, from a higher source of instructions, which is of course the brain.
Melatoninâ€”the original hypnotic
The pineal gland is an endocrine gland that secretes melatonin, a hormone, into the blood and, more importantly, the cerebrospinal fluid (CSF). The melatonin in the blood is ten times higher at night than in the daytime blood.
Melatonin begins to be made during an infant’s 3rd to 4th month of age, when sleep patterns begin consolidating at nighttime.
Synthetic melatonin, a sleep-aid, has been shown to affect the circadian rhythm, but before going out to buy it, know that melatonin’s receptor sites become desensitized (less stimulated by melatonin) in larger doses.
Today’s anti-melatoninâ€ ...
