Solution
The correct answer is option (1) as
- Parturition is induced by a complex neuroendocrine mechanism. The signals for parturition originate from the fully developed foetus and the placenta that induce mild uterine contractions called foetal ejection reflex.
- Placenta acts as an endocrine tissue and produces several hormones like hCG, hPL estrogens, progestogens, etc.
- The milk produced during the initial few days of lactation is called colostrum that contains several antibodies absolutely necessary to develop resistance for the new-born babies.
Fimbriae helps in collection of the ovum after ovulation.
