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.
1 The anterior pituitary or adenohypophysis is a classical gland composed predominantly of cells that secrete protein hormones. 2  The posterior pituitary or neurohypophysis is not a separate organ, but an extension of the hypothalamus.hese hypothalamic hormones reach the anterior pituitary through the following route: 1  A branch of the hypophyseal artery ramifies into a capillary bed in the lower hypothalamus, and hypothalmic hormones destined for the anterior pituitary are secreted into that capillary blood.
