The ________ is the Endometrial Layer That Undergoes Dramatic Changes

Question

The ________ is the endometrial layer that undergoes dramatic changes during the menstrual cycle.
A) functional layer
B) corpus albicans
C) basal layer
D) corpus luteum
E) stroma

Accepted Answer

The functional layer of the endometrium is the layer that thickens and undergoes changes during the menstrual cycle, in preparation for possible implantation of a fertilized egg. If implantation does not occur, this layer is shed during menstruation. The basal layer, stroma, and corpus albicans are also parts of the endometrium but do not undergo the same changes during the menstrual cycle as the functional layer. The corpus luteum is a structure that develops in the ovary after ovulation and produces hormones to support a potential pregnancy.
