Final answer:

Oxytocin release is regulated via a positive feedback mechanism during childbirth and in response to infant suckling.


Explanation:

Oxytocin is released from the posterior pituitary and plays a crucial role in stimulating uterine contractions during childbirth. These contractions trigger the release of more oxytocin in a positive feedback mechanism, leading to intensified contractions until the baby is delivered. Additionally, oxytocin is also released in response to the suckling of an infant, further highlighting its regulatory functions.
