Released:GHRH

Inhibitor: SS aka GHIH
Targets: Liver and other tissues, Growth and Development, Metabolic

Question 14

Prolactin

Answer 14

Cell Type: Mammotroph (lactotroph)
(Preg: increase Size and #)

Prolactin releasing factors : TRH

Inhibitors: GAP (GnRH associated peptide), DOPAMINE, SS

Targets: breast., lactation, milk, growth, suppressed menstrual fx.

Question 15

Prolactin- makes milk !

Answer 15

Oxytocin- Ejects the milk

Question 16

Prolactin is ALWAYS INHIBITED

Answer 16

• if DOPAMINE is inhibited, then Prolactin will be increased

Question 17

Hypothalamo - Post. Pit. Axis

Answer 17

Hormone is made in cell body of neuron,
Vesicles containing hormone are stored in posterior pituitary,
Hormones are dumped into circulation

Question 18

Oxytocin

Answer 18

-Myometrium contractions during delivery
- Ejects Milk

Question 19

ADH- Vasopressin

Answer 19

Renal actions - Increase H2O absorption
- Water retention

Vascular act.
- VASOCONSTRICTION, INCREASED PLASMA VOLUME (decreases Pc),

Controlled by: Osmoreceptors and Volume/Pressure receptors
