Hormones Flashcards
Prepares endometrium to allow implantation
Progesterone
Stimulates glands in endometrium to secrete nutrients for early embryo
Progesterone
Loosens and relaxes muscles, joints and ligaments to help the body stretch
Relaxin
Loosens and relaxes muscles, joints and ligaments to help the body stretch
Relaxin
Helps the uterus grow
Oestrogen
Maintains uterine lining
Progesterone
Regulates other key hormones and triggers the development of baby’s organs
Oestrogen
Secreted by placenta, thicken uterine lining to stop menstruation
HCG
Test for to confirm pregnancy
HCG
Stimulates uterine contractions in labour and childbirth
Oxytocin
Stimulates milk ejection reflex
Oxytocin
Promotes the growth of breast tissue
Prolactin
Released by skin to skin
Oxytocin
Food cravings due to
Progesterone
Insulin
Glucagon
Food aversions due to
Oestrogen
Reduces gastric muscle tone/motility
Progesterone
What happens to MOTILIN levels in pregnancy and the effect of this
Decrease
delayed gastric emptying
What hormone increases intestinal transit time in pregnancy
Progesterone due to effect (decrease in tone) on smooth muscle
Hormone causing constipation and how
Progesterone…. transit time in colon longer so more water absorbed
Why are plasma proteins, bilirubin. Serum enzymes and lipid altered
Oestrogen and haeomodilution
What does progesterone do to gall bladder
Decrease muscle tone
Decrease motility
Volume increase emptying decrease
Retention of bile salts = itchy
When fertilisation occurs, the corpus luteum continues producing hormones to support the pregnancy until the placenta has developed. Which hormone does this?
a. Human placental lactogen (hPL)
b. Human chorionic gonadotrophin (HCG)
c. Relaxin
d. Progesterone
B) HCG
Which hormone prepares and thickens uterus lining
Oestrogen
Which hormone maintains uterus lining
Progesterone
Which hormone maintains uterus lining
Progesterone
Which causes maturation of egg on ovary?
FSH
Hormones produced by placenta (6)
Oestrogen, progesterone, hcg, hpl, placental growth hormone, relaxin
What does hpl do?
Not fully understood - believed help prepare growth mammary glands in preparation for milk production. Helps regulate maternal metabolism
