Answer» Correct Answer - Option 2 : Childbirth and lactation Concept: Oxytocin is a hormone released from the posterior pituitary gland. The main of oxytocin is involved in uterine contractions during childbirth and lactation after childbirth. Other functions involve influence on the stress response, anxiety, and bonding. Explanation: Oxytocin is synthesized in hypothalamic magnocellular neurons and released from the posterior pituitary into the bloodstream. Gq coupled G-protein Coupled Receptor (GPCR) is the oxytocin receptor. The receptors' activation leads to the influx of calcium ions that lead to smooth contraction. Therefore, it causes contraction of the smooth muscles of the uterus. These contractions also reduce the bleeding. Oxytocin also acts on myoepithelial cells in the breast, resulting in the contraction of muscles and ejection of the milk.
