Question

Where do signals for parturition originate from?

Answer 1

Parturition:

1. Parturition is the process of giving birth to a child.
2. Neuroendocrine signals cause parturition.

Signals of parturition:

1. When the foetus is fully developed, signals from the placenta and the foetus cause the uterine wall to contract.
2. The maternal pituitary gland receives signals from uterine contractions to release the oxytocin hormone.
3. Oxytocin causes uterine contractions to be strong, which forces the foetus outside.
