Difficulty: MediumReproductive Systems and Processes in Organisms

Match each mammalian reproductive hormone listed on the left with its primary physiological role during reproduction on the right.

  • Follicle-Stimulating Hormone (FSH)Stimulates growth and development of ovarian follicles
  • Luteinizing Hormone (LH)Triggers ovulation and promotes corpus luteum formation
  • ProgesteroneMaintains the vascularized uterine lining during gestation
  • OxytocinInduces rhythmic contractions of the uterine wall during labor

Answer

Follicle-Stimulating Hormone (FSH) matches with stimulating growth and development of ovarian follicles; Luteinizing Hormone (LH) matches with triggering ovulation and promoting corpus luteum formation; Progesterone matches with maintaining the vascularized uterine lining during gestation; Oxytocin matches with inducing rhythmic contractions of the uterine wall during labor.
Each hormone is correctly matched with its specific physiological role: Follicle-Stimulating Hormone drives ovarian follicle growth, Luteinizing Hormone stimulates ovulation and corpus luteum development, Progesterone maintains the uterine mucosal lining for implantation, and Oxytocin promotes uterine contractions during parturition.

Step-by-Step Solution

1
Analyze the role of pituitary gonadotropic hormones acting on the ovaries.
FSH promotes follicle development, whereas LH induces ovulation and corpus luteum formation.
Anterior pituitary gonadotropins directly regulate ovarian follicular phases.
2
Identify the primary function of the ovarian steroid hormone progesterone.
Progesterone maintains the endometrial lining of the uterus to support pregnancy.
High progesterone levels prevent menstruation and support implantation.
3
Determine the physiological action of oxytocin during childbirth.
Oxytocin stimulates powerful myometrial contractions to expel the fetus during parturition.
Oxytocin acts on uterine smooth muscle receptors near the end of gestation.
