Foetal ejection reflex in human female is induced bya)Pressure exerted by amniotic fluidb)Release of oxytocin from pituitaryc)Fully developed foetus and placentad)Differentiation of mammary glandsCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Foetal ejection reflex in human female is induced by fully developed foetus and placenta.

Parturition is an induced Complex neuroendocrine mechanism. In this signals are originated from a fully developed fetus and placenta.

This lead to mild uterine contractions and hence fetal ejection reflex. Then oxytocin acts on uterine muscles leading to strong uterine contractions. This further continues to stronger and stronger contractions

When a woman is in a lithotomy or semi-sitting position, the Foetal Ejection Reflux is impaired and the increased pain caused by the sacrum’s inability to move as the baby descends can be intolerable.

Answer

Parturition is an induced Complex neuroendocrine mechanism. In this signals are originated from a fully developed fetus and placenta. This lead to mild uterine contractions and hence fetal ejection reflex. Then oxytocin acts on uterine muscles leading to strong uterine contractions. This further continues to stronger and stronger contractions. As a result, the baby is expelled out of the uterus with placenta through the birth canal. IN OPINION THE ANSWER CAN BE BOTH B AND C

Answer

The correct answer is option 'B' - Release of oxytocin from pituitary.

Explanation:
The foetal ejection reflex is a physiological response that occurs during childbirth, specifically during the second stage of labour when the baby is being delivered. It is a complex process that involves various hormonal and mechanical factors.

1. Oxytocin release: The release of oxytocin from the pituitary gland plays a crucial role in inducing the foetal ejection reflex. Oxytocin is a hormone that is produced by the hypothalamus and released by the pituitary gland. It is also known as the 'love hormone' as it plays a role in social bonding and attachment. During childbirth, oxytocin is released in response to the stretching of the cervix and the pressure exerted by the baby's head on the birth canal. This release of oxytocin stimulates the contractions of the uterine muscles, leading to the expulsion of the baby.

2. Uterine contractions: The contractions of the uterine muscles are essential for the foetal ejection reflex. These contractions help to push the baby down the birth canal and facilitate its delivery. Oxytocin is responsible for stimulating these contractions. It acts on the smooth muscles of the uterus, causing them to contract and push the baby downwards.

3. Maternal relaxation: Along with oxytocin release, maternal relaxation is also crucial for the foetal ejection reflex. When the mother is relaxed and in a comfortable position, it allows for the optimal functioning of the uterine muscles and the birth canal. This relaxation can be facilitated by various techniques such as deep breathing, massage, and the support of a birth partner or healthcare provider.

4. Hormonal feedback loop: The release of oxytocin during childbirth is regulated by a hormonal feedback loop. As the baby's head exerts pressure on the birth canal, it stimulates the release of oxytocin. This oxytocin then further stimulates uterine contractions, leading to more pressure on the birth canal, and the cycle continues until the baby is delivered.

In conclusion, the foetal ejection reflex in human females is primarily induced by the release of oxytocin from the pituitary gland. This hormone stimulates uterine contractions, which push the baby down the birth canal and facilitate its delivery. Maternal relaxation and the hormonal feedback loop also play important roles in this process.
