//Key Understandings//
> When the pancreas doesn't produce insulin, Type I Diabetes results. > Antagonistic hormones are pairs of hormones that have opposing effects on a certain bodily component and work together to keep it at homeostasis.
 * =====The primary purpose of the endocrine system is to maintain homeostasis=====
 * The endocrine system is primarily composed of glands that secrete hormones.
 * Key glands: thyroid, pituitary, pineal, thymus, adrenal
 * Some athletes illegally receive injections of growth hormones to improve performance.
 * Also use testosterone, steroids, blood doping.
 * Insulin is secreted by beta cells in the pancreas.
 * =====The pancreas not producing insulin causes type I diabetes.=====
 * =====Type II diabetes is normally caused by obesity.=====
 * One example of a secondary messenger is cAMP.
 * Peptide hormones activate cAMP to start the enzymatic process of glycogen breakdown.
 * =====The hypothalamus controls the secretions of the pituitary gland.=====
 * =====Leptin (a hunger hormone) is produced in the adipose tissue.=====
 * Acts on the hypothalamus to inhibit hunger.
 * =====The pituitary gland has two parts: posterior and anterior.=====
 * =====The thyroid is the largest endocrine gland.=====
 * =====Once stimulated by a hormone (such as epinephrine), the G-protein coupled receptors activate a secondary messenger to prompt various bodily responses of the sympathetic nervous system as a response to an immediate stressor.=====
 * =====Too little iodine in one’s diet results in a condition called hypothyroidism.=====
 * =====One’s neck grows to form a goiter; this can be avoided by purchasing iodized salt.=====
 * Hyposecretion of adrenal hormones can lead to Addison's Disease, famously hid by John F. Kennedy.
 * Once stimulated by a hormone (such as epinephrine), G-protein coupled receptors activate a secondary messenger to prompt various bodily responses (such as increased heart rate).
 * An example of antagonistic hormones is Parathyroid Hormones (PTH) and Calcitonin.
