Which of these is not an important component of initiation of parturition in humans?
1 Release of oxytocin
2 Release of prolactin
3 Increase in estrogen and progesterone ratio
4 Synthesis of prostaglandins
Explanation:
The signals for child birth (parturition) originate from the fully developed foetus and placenta which induce mild uterine contractions called foetal ejection reflex. This causes quick release of oxytocin from the maternal posterior lobe of pituitary gland which induces labour pains. Prostaglandins, progesterone and estrogen also play a role. Prolactin is the hormone which induces lactation and has no role in parturition.

Parturition is induced by a complex neuroendocrine mechanism involving: i. The hormone that has 2 peaks in menstrual cycle ii. Relaxin. iii. Milk let out hormone iv. Supra renal gland
1 \(\mathrm{i}\), ii
2 i, iii
3 i, ii, iv
4 iii, iv
Explanation:
Oxytocin - milk let out hormone, ACTHcorticosteroids are the hormones that are actually involved in parturition process, others are pregnancy hormones .

Delivery of developed foetus is
1 Abortion
2 Oviposition
3 Parturition
4 Conception
Explanation:
When the signals along with the placenta for a possible delivery and hence childbirth takes place also known as parturition.

The duration of gestation period is
1 Of fertilization
2 Between preparation of sex cells and fertilization
3 Between fertilization and parturition
4 Between egg growth and ovulation
Explanation:
The duration of Gestation period is between fertilization and parturition. The average duration of human pregnancy is about 9 months which is called the gestation period.
