media

Small, round, pea-sized structure

Controls all of the other glands in the body (but controlled by the hypothalamus

Anterior & Posterior lobes

Pituitary Gland

3

​Anterior Lobe Hormones

Growth Hormone- promotes the growth of body structures

Thyroid-stimulating hormone- affects the growth and functioning of the thyroid gland

Follicle-stimulating hormone- and Luteinizing hormone LH- gonadotropins>they act on the gonads/ovaries

Prolactin- mammary glands>produce milk

Adrenocorticotropic hormone (ACTH) acts on adrenal glands  secrete glucocorticoids including cortisol.

4

​Posterior Lobe Hormones

  • Oxytocin- contractions

  • Antidiuretic hormone- acts on kidneys to increase the absorption of water
