1. | Increase in oestrogen and progesterone ratio |
2. | Synthesis of prostaglandins |
3. | Release of oxytocin |
4. | Release of prolactin |
Which one of the following is not the function of placenta?
1. | Secretes estrogen |
2. | Facilitates removal of carbon dioxide and waste material from embryo |
3. | Secretes oxytocin during parturition |
4. | Facilitates supply of oxygen and nutrients to embryo |
Signals for parturition originate from:
1. Both placenta as well as fully developed foetus
2. Oxytocin released from maternal pituitary
3. Placenta only
4. Fully developed foetus only
The first movements of the foetus and the appearance of hair on its head are usually observed during which month of pregnancy?
1. Fourth month
2. Fifth month
3. Sixth month
4. Third month
Signals from fully developed foetus and placenta ultimately lead to parturition which requires the release of:
1. Oxytocin from maternal pituitary
2. Oxytocin from foetal pituitary
3. Relaxin from the placenta
4. Estrogen from placenta
Foetal ejection reflex in human female is induced by:
1. pressure exerted by aminotic fluid
2. release of oxytocin from pituitary
3. fully developed foetus and placenta
4. differentiation of mammary glands
