plays a role in regulating body's circadianrhythm

Question 33

pituitary gland

Answer 33

Divided into anterior and posteriorlobes

Question 34

anterior lobe pituitary

Answer 34

somatotropin (stimulates cells to grow and divide) Prolactin (stimulates milk production) Melanocyte-stimulating hormone (Stimulates melanocytes to produce more melanin)

Question 35

Anterior Pituitary | master gland

Answer 35

``` Thyroid-stimulating hormone (Regulates function of thyroid gland) Adrenocorticotropin hormone (Regulates function of adrenal cortex) Gonadotropins ```

Question 36

Gonadotropins

Answer 36

``` Follicle-stimulating hormone (Responsible for development of ova and sperm –Also stimulates ovary to secrete estrogen) Luteinizing hormone (Stimulates secretion of sex hormones –Plays a role in releasing ova in females) ```
