Which layer of uterus nourishes the embryo after implantation?
- A. Cervical epithelium
- B. Myometrium
- C. Endometrium
- D. Perimetrium
Explanation
The endometrium is the inner glandular lining, thickened and richly supplied with blood by progesterone, and it is where the blastocyst implants and from which the maternal part of the placenta develops. The myometrium is the thick smooth muscle whose contractions expel the baby at birth, and the perimetrium is the outer covering. Shedding of the endometrium is what menstruation consists of.
