<p>what is this</p>

what is this

The hypothalamus (hypo-: below, under), master control center for endocrine system, controls autonomic nervous system, regulates body temp, food, water intake, emotional behavior, sleep/wake cycle.

<p>Locate the pituitary gland.</p>

Locate the pituitary gland.

Split into anterior and posterior,

  • Anterior pituitary produces the following hormones: thyroid-stimulating (TSH), prolactin (PRL), adrenocorticotropic (ACTH), growth (GH), luteinizing (LH), melanocyte-stimulating (MSH), and follicle-stimulating (FSH)

  • Posterior pituitary stores and releases: antidiuretic hormone (ADH) and oxytocin (OT)

Does not produce any hormones. ADH and OT produced in hypothalamus
