Hypothalamus/ Pituitary/ Pineal

Hypothalamus/ Pituitary/ Pineal

1. Hypothalamus

   • Location: Ventral diencephalon
     • Description: COllection of nuceli located inferior to thalamus
       • Function: Maintains sleep/wake cycle; regulates body temperature and emotional behavior, controls autonomic nervous system

2. Infundibilum of pituitary gland

   • Location: ventral surface of diencephalon (hypothalamus) at midline
     • Description: Contains hypothalamus-hypophysial tract
       • Function: Transmits antidiuretic hormone (ADH) and oxytocin through hypothalamic-hypophysial tract to posterior pituitary

3. Pineal Gland

   • Location: Diencephalon (epithalamus)
     • Description: Pea sized endocrine gland; attached to roof of third ventricle
       • Function: Secretes melatonin; modified activity in endocrine organ

4. Pituitary gland

   • Location: midline of middle cranial fossa; rests in hypophysial fossa of sphenoid bone
     • Description: small, oval bilobed endocrine gland
       • Function: Anterior pituitary produces hormones; posterior pituitary stores and releases; antidiuretic hormone and oxytocin
