Pituitary Gland

Question 1

what 6 hormones doe the anterior pituitary gland produce

Answer 1

Adrenocorticotropic hormone (ACTH)
Follicle-stimulating hormone (FSH)
Growth hormone (GH)
Luteinizing hormone (LH)
Prolactin
Thyroid-stimulating hormone (TSH)

Question 2

what is the function of the hormone Adrenocorticotropic hormone (ACTH)

Answer 2

ACTH stimulates the adrenal glands to produce hormones.

Question 3

what is the function of the hormone Follicle-stimulating hormone (FSH)

Answer 3

FSH works with LH to ensure normal functioning of the ovaries and testes.

Question 4

what is the function of the hormone Growth hormone (GH)

Answer 4

GH is essential in early years to maintaining a healthy body composition and for growth in children. In adults, it aids healthy bone and muscle mass and affects fat distribution.

Question 5

what is the function of the hormone Luteinizing hormone (LH)

Answer 5

LH works with FSH to ensure normal functioning of the ovaries and testes.

Question 6

what is the function of the hormone Prolactin

Answer 6

Prolactin stimulates breast milk production.

Question 7

what is the function of the hormone Thyroid-stimulating hormone (TSH)

Answer 7

TSH stimulates the thyroid gland to produce hormones.

Question 8

what 2 hormones are produced in the posterior pituitary gland

Answer 8

Anti-diuretic hormone (ADH)

Oxytocin

Question 9

what is the function of the Anti-diuretic hormone (ADH)

Answer 9

This hormone prompts the kidneys to increase water absorption in the blood.

Question 10

what is the function of the hormone Oxytocin

Answer 10

Oxytocin is involved in a variety of processes, such as contracting the uterus during childbirth and stimulating breast milk production.

Question 11

what 6 hormones does they hypothalamus secrete which are released into the blood in the capillaries and travel immediately – in portal veins – to a second capillary bed in the anterior lobe of the pituitary, where they exert their effects.

Answer 11

Thyrotropin-releasing hormone (TRH)
Gonadotropin-releasing hormone (GnRH)
Growth hormone-releasing hormone (GHRH)
Corticotropin-releasing hormone (CRH)
Somatostatin
Dopamine

Question 12

what is the function of Thyrotropin-releasing hormone (TRH)

Answer 12

When it reaches the anterior lobe of the pituitary it stimulates the release there of

• thyroid-stimulating hormone (TSH)
• prolactin (PRL)

Question 13

what is the function of Gonadotropin-releasing hormone (GnRH)

Answer 13

Its secretion at the onset of puberty triggers sexual development, and from then on it is essential for normal sexual physiology in both males and females.

Question 14

what is the function of Growth hormone-releasing hormone (GHRH)

Answer 14

As its name indicates, GHRH stimulates cells in the anterior lobe of the pituitary to secrete growth hormone (GH).

Question 15

what is the function of Corticotropin-releasing hormone (CRH)

Answer 15

As its name indicates, its acts on cells in the anterior lobe of the pituitary to release adrenocorticotropic hormone (ACTH)

CRH is also synthesized by the placenta and seems to determine the duration of pregnancy.

Question 16

what is the function of Somatostatin

Answer 16

Somatostatin acts on the anterior lobe of the pituitary to:

• inhibit the release of growth hormone (GH)
• inhibit the release of thyroid-stimulating hormone (TSH)

Question 17

what is the function of Dopamine

Answer 17

inhibiting the release of prolactin (PRL) from the anterior lobe of the pituitary
