Cortisol Response ~ The synthesis of cortisol in the adrenal gland is stimulated by the anterior lobe of the pituitary gland with adrenocorticotropic hormone (ACTH); ACTH production is in turn stimulated by corticotropin-releasing hormone (CRH), which is released by the hypothalamus.
The pituitary has two parts. The anterior lobe is the source of prolactin, GH, thyroid-stimulating hormone (TSH, controlling the thyroid), gonadotropic hormones (LH and FSH, controlling testes or ovaries) and adrenocorticotropic hormone (ACTH, controlling the adrenal glands). The posterior lobe contains nerve fibers coming from the brain (hypothalamus) storing oxytocin (necessary for uterine contractions during delivery) and anti-diuretic hormone.
ACTH Also known as: Corticotropin; Cosyntropin Formal name: Adrenocorticotropic Hormone Related tests: Cortisol, Cortrosyn (ACTH) Stimulation Test, Dexamethasone Suppression Test
Emotional tears contain more protein-based hormones - prolactin, adrenocorticotropic hormone, and leucine enkephalin - all of which are produced by our body when under stress. The body gets rid of these chemicals through tears.
Cushing's syndrome describes the signs and symptoms associated with prolonged exposure to very high levels of the hormone cortisol. This can be caused by taking glucocorticoid drugs, or diseases that result in excess cortisol, adrenocorticotropic hormone (ACTH), or CRH levels. Cushing's disease refers to a pituitary-dependent cause of Cushing's syndrome: a tumor (adenoma) in the pituitary gland produces large amounts of ACTH, causing the adrenal glands to produce elevated levels of cortisol.
Hormones of the Posterior Pituitary: Antidiuretic Hormone (ADH), and Oxytocin. Hormones of the Hypothalamus and Anterior Pituitary: Growth Hormone (GH), Prolactin (PRL), Gonadotropins - Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH), Thyroid Stimulating Hormone (TSH), and Adrenocorticotropic Hormone (ACTH).
The six hormones of the anterior pituitary "FLAT PiG" F(SH) = Follicle-Stimulating Hormone L(H) = Leuteinizing Hormone A(CTH) = Adrenocorticotropic Hormone T(SH) = Thyroid Stimulating Hormone P(rolactin) = stimulates milk in female mammary glands i(gnore) G(H) = Growth Hormone The posterior pituitary gland has only two hormones it stores and releases: Oxytocin = during childbirth it increases strength of contractions ADH (anti-diuretic hormone) = regulates the concentration of urine
