Initiation of Parturition
Initiation of parturition, or the process of childbirth, is regulated by a complex interplay of hormones. Among the hormones involved, corticosteroids play a significant role in triggering the onset of labor.
Role of Corticosteroids
- Corticosteroids, produced by the fetal adrenal gland, are released into the maternal circulation.
- These hormones stimulate the production of enzymes that convert progesterone into estrogen in the placenta.
- The increase in estrogen levels triggers a cascade of events leading to the onset of labor, including the production of prostaglandins and increased sensitivity of the myometrium to oxytocin.
Other Hormones
- ACTH (adrenocorticotropic hormone) is involved in the regulation of corticosteroid production.
- Oxytocin, known as the "love hormone," plays a crucial role in uterine contractions during labor.
- hCG (human chorionic gonadotropin) is primarily involved in maintaining the corpus luteum during early pregnancy.
Correct Answer
In the context of parturition initiation, the correct option is B: ACTH, corticosteroid, oxytocin. This combination of hormones reflects the sequential events leading to the onset of labor, with corticosteroids playing a central role in the process.
