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.
While these hormones are produced by the anterior pituitary, their production is controlled by regulatory hormones produced by the hypothalamus. These regulatory hormones can be releasing hormones or inhibiting hormones, causing more or less of the anterior pituitary hormones to be secreted.
