Multiple Choice

What occurs during the proliferative phase of the menstrual cycle?

The endometrial lining is shed through menstruation.

The endometrium thickens in preparation for potential implantation.

Ovulation occurs and the egg is released from the ovary.

The corpus luteum forms and secretes progesterone.

Verified step by step guidance

Understand the phases of the menstrual cycle: The menstrual cycle is divided into several phases, including the menstrual phase, proliferative phase, ovulation, and secretory phase.

Identify the proliferative phase: This phase occurs after menstruation and before ovulation. It is characterized by the rebuilding of the endometrial lining.

Recognize the role of estrogen: During the proliferative phase, estrogen levels rise, stimulating the thickening of the endometrium. This prepares the uterus for potential implantation of a fertilized egg.

Differentiate from other phases: Unlike the menstrual phase where the lining is shed, or the secretory phase where progesterone maintains the lining, the proliferative phase focuses on growth and thickening.

Connect to the overall cycle: The thickening of the endometrium during the proliferative phase is crucial for a successful implantation if fertilization occurs after ovulation.
