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 hormone which the anterior pituitary gland produces is called ADH. The ADH hormone is responsible for the balance of water within the human body. These are the stages in which the ADH hormone acts if there is too little water: 1. The hypothalamus (a part of the brain) detects too little water in blood.
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.
