Hormone secreted by the adenohypophysis (anterior pituitary)
1.Thyroid stimulating hormone (TSH)
Triggers the release of thyroid hormones
Thyrotropin releasing hormone promotes the release of TSH
2.Adrenocorticotropic hormone (ACTH)
Stimulates the release of glucocorticoids by the adrenal gland
Corticotrophin releasing hormone causes the secretion of ACTH
3.Follicle stimulating hormone (FSH)
Stimulates follicle development and estrogen secretion in females and sperm production in males
4.Leutinizing hormone (LH)
Causes ovulation and progestin production in females and androgen production in males
Gonadotropin releasing hormone (GNRH) promotes the secretion of FSH and LH
5.Prolactin (PH)
Stimulates the development of mammary glands and milk production
6.Growth hormone (GH or somatotropin)
Stimulates cell growth and replication through release of somatomedins or IGF
Secretion is controlled by Growth-hormone releasing hormone (GH-RH) and Growth-hormone inhibiting hormone (GH-IH)
7.Melanocyte stimulating hormone (MSH)
May be secreted by the pars intermedia during fetal development, early childhood, pregnancy or certain diseases
Stimulates melanocytes to produce melanin
Posterior pituitary contains axons of hypothalamic nerves
8.ADH
Neurons of the supraoptic nucleus manufacture antidiuretic hormone (ADH)
Decreases the amount of water lost at the kidneys
Elevates blood pressure
9.Oxytocin
Neurons of the paraventricular nucleus manufacture oxytocin
Stimulates contractile cells in mammary glands
Stimulates smooth muscle cells in uterus
