Question

which of the following neurotransmitters is released in excess during the onset of lactation and breastfeeding in mothers who have just given birth?

acetylcholine

oxytocin

dopamine

serotonin

Explanation:

Oxytocin is known as the "love hormone" and plays a crucial role in lactation and breastfeeding. During the onset of lactation and breastfeeding after childbirth, oxytocin is released in excess to stimulate milk ejection (let - down reflex) and also promotes bonding between the mother and the infant. Acetylcholine is involved in muscle movement and other functions, dopamine is related to reward and motivation, and serotonin is involved in mood regulation and other processes, none of which are primarily associated with lactation onset in the same way as oxytocin.

Answer:

B. Oxytocin
