Question 1

What are the 5 releasing hormones and 2 inhibiting hormones?

Answer 1

5 Releasing: (RH)
Growth hormone (GHRH)
Thyrotropin (TRH)
Gonadotropin (GnRH)
Prolactin (PRH)
Corticotropin (RH)

2 Inhibiting: (IH)

Human Growth Hormone (hGH)
bone & skeletal muscle
Insulin growth factors (IGF)

Question 3

Trace the path of Thyrotropin (TRH)

Answer 3

Thyrotropin (TRH)
Thyrotrophs (TRH) Anterior Pituitary
thyroid-stimulating hormone (TSH)
thyroid gland
T3 & T4

Question 4

Trace the path of Gonadotropin (GnRH)

Answer 4

Gonadotropin (GnRH)
Gonadotrophs (GnRH) Anterior Pituitary
follicle-stimulating hormone (FSH) & luteinizing hormone (LH)
ovaries and testes
sex hormones (estrogen and progesterone in females and testosterone in males)

Question 5

Trace the path of Prolactin (PRH)

Answer 5

Prolactin (PRH)
Lacotrophs (PRH) Anterior Pituitary
prolactin (PRL)
mammary glands (milk production)

Question 6

Answer 6

Corticotropin (RH)
Corticotrophs (CRH) Anterior Pituitary
adrenocorticotropic hormone (ACTH) & melanocyte-stimulating hormone (MSH)

Question 7

Trace the path of Growth hormone inhibiting (GHIH)

Answer 7

Growth hormone (GHIH)
Somatotrophs in the Anterior Pituitary to shut down release of human growth hormone

Question 8

Trace the path of Prolactin inhibiting (PIH)

Answer 8

Prolactin (PIH)
Lacotrophs in the Anterior Pituitary to shut down the release of prolactin
