1

which pituitary lobe releases both growth hormone(GH) and prolactin(PRL)

anterior lobe

2

which pituitary lobe releases both thyroid stimulating hormone(TSH) and adrenocorticotropic hormone(ACTH)

anterior lobe

3

which pituitary lobe secretes both follicle stimulating hormone(FSH) and luteinising hormone(LH)

anterior lobe

4

which pituitary lobe secretes both oxytocin and antidiuretic hormone(ADH)

posterior lobe

5

which of the pituitary gland hormones are peptides

Prolactin, Adrenocorticotropic hormone, Oxytocin and Antidiuretic hormone

6

which of the pituitary gland secretions are proteins

growth hormone

7

which of the pituitary gland secretions are glycoproteins

thyroid stimulating hormone, follicle stimulating hormone and luteinising hormone

8

what is the function of the growth hormone(GH)

promotes growth of body tissues

9

what is the function of prolactin(PRL)

promotes milk production from mammary glands

10

what is the function of thyroid stimulating hormone(TSH)

stimulates thyroid hormone release from thyroid

11

what is the function of adrenocorticotropic hormone(ACTH)

stimulates hormone release by adrenal cortex

12

what is the function of follicle stimulating hormone(FSH)

stimulates gamete production in gonads

13

what is the function of luteinising hormone(LH)

stimulates androgen production by gonads

14

what is the function of antidiuretic hormone(ADH)

stimulates water reabsorption in kidneys

15

what is the function of oxytocin

stimulates uterine contractions during childbirth

16

what is the role of the hypothalamus in pituitary gland secretions

secretes releasing or inhibitory hormones to stimulate or prevent secretion from anterior lobe

17

briefly describe the hypophyseal portal system

hypothalamic neurones secrete releasing or inhibitory hormones, then hypophyseal portal veins carry hormones to 2nd capillary bed of anterior pituitary
