Both assertion and reason are false.
Because parturition is induced by oxytocin which is released by posterior pitutary directly to the organ(uterus)to contract for parturition.so assertion is false.
maternal pituitary release prolactin which causes production of milk.so reason is false.

Introduction:
Parturition, also known as childbirth, is the process by which a baby is born from the mother's uterus. It is a complex physiological process that involves a series of events leading to the expulsion of the fetus. The onset of parturition is triggered by various hormonal and neural signals.

Maternal Pituitary and Parturition:
The maternal pituitary gland plays a crucial role in the initiation and progression of parturition. It secretes several hormones that are involved in the process. One of these hormones is prolactin.

Role of Prolactin:
At the end of the gestation period, the maternal pituitary gland releases prolactin. Prolactin is primarily known for its role in milk production and breastfeeding. However, it also has an important function in parturition.

Uterine Contractions:
Prolactin stimulates the uterine muscles, leading to contractions. These contractions are essential for the expulsion of the fetus. They help in dilating the cervix and pushing the baby through the birth canal.

Neural Signals and Parturition:
While prolactin from the maternal pituitary gland plays a significant role in initiating uterine contractions, parturition is also influenced by neural signals. The hypothalamus, a region of the brain, releases oxytocin, a hormone involved in the contraction of the uterine muscles.

Oxytocin and Uterine Contractions:
Oxytocin is released by the posterior pituitary gland in response to neural signals from the hypothalamus. It acts on the uterine muscles, causing them to contract. These contractions help in the progress of labor and facilitate the delivery of the baby.

Interaction between Hormonal and Neural Signals:
The release of prolactin from the maternal pituitary gland and oxytocin from the hypothalamus work together to induce and sustain uterine contractions during parturition. The hormonal and neural signals complement each other and ensure the successful delivery of the baby.

Conclusion:
In conclusion, parturition is a complex process that involves the interaction between hormonal and neural signals. The maternal pituitary gland releases prolactin, which stimulates uterine contractions. Additionally, neural signals from the hypothalamus trigger the release of oxytocin, further enhancing uterine contractions. Both hormonal and neural signals play crucial roles in the initiation and progression of parturition.
