Parasomnias are disruptive sleep disorders that can occur during arousals from REM sleep or partial arousals from non-REM sleep. Parasomnias include nightmares, night terrors, sleepwalking, confusional arousals, and many others.
The anterior pituitary gland produces 6 hormones, they are: Growth hormones (GH) to the bones and muscles, thyrotropic hormones (TSH) to the thyroid, prolactin (PRL) to the mammary glands, adrenocorticotropic hormones (ACTH) to the adrenal cortex, follicle-stimulating hormones (FSH) and luteinizing hormones (LH) to the testes or ovaries.
Four of the six anterior pituitary hormones are tropic hormones that regulate the function of other endocrine organs. Most anterior pituitary hormones exhibit a diurnal rhythm of release, which is subject to modification by stimuli influencing the hypothalamus.
