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.
Some of these anterior pituitary hormones induce other glands to secrete their hormones. The rise in blood levels of the hormones produced by the final target glands (for example, the ovary or thyroid) inhibits the release of anterior pituitary hormones.
