Hormones secreted by the pituitary gland

This include hormone secreted by adenohypophysis (anterior pituitary)and neurohypophysis (posterior pituitary)

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

The hormones secreted by posterior lobe of the pituitary gland (neurohypophysis)

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
