During pregnancy the levels of thyroxin:
1. Increase several folds in maternal blood
2. Increases several folds in fetal blood
3. Decreases several folds in maternal blood
4. Decreases several folds in fetal blood
The first movements of the fetus and the appearance of hair on the head are usually observed during:
1. 2nd month
2. 3rd month
3. 5th month
4. 6th month
The human fetus develops limbs and digits:
1. After one month of pregnancy
2. By the end of second month of pregnancy
3. During the fifth month of pregnancy
4. By the end of second trimester of pregnancy
During parturition, the fetal ejection reflex triggers the release of:
1. | An increasing amount of estrogen and a decreasing amount of progesterone from the placenta |
2. | A decreasing amount of estrogen and an increasing amount of progesterone from the placenta |
3. | Oxytocin from the maternal pituitary |
4. | GnRH from the fetal hypothalamus |
Foetal ejection reflex in human female is induced by
1. pressure exerted by amniotic fluid
2. release of oxytocin from pitutary
3. fully developed foetus and placenta
4. differentiation of mammary glands
