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.
The posterior pituitary is, in effect, a projection of the hypothalamus. It does not produce its own hormones, but only stores and releases the hormones created by the hypothalamus, whereas the anterior pituitary produces and secretes its own hormones.lthough the hypothalamus does not produce the hormones of the anterior pituitary as in the posterior pituitary, it plays an important role in their production. Releasing hormones synthesized by hypothalamic neurons travel down axons and diffuse into the primary plexus of the hypophyseal portal system.
