During fertilization, the portion of the decidua covering the blastocyst is called:

  • A. Decidua basalis
  • B. Decidua Vera
  • C. Decidua parietalis
  • D. Decidua capsularis
Correct Answer: D

Rationale: During fertilization, the decidua capsularis is the specific portion of the decidua that covers the blastocyst, providing protection and support. Decidua basalis refers to the part of the decidua located at the site of implantation on the maternal side. Decidua vera is the remainder of the decidua lining the uterus. Decidua parietalis is the portion of the decidua that lines the rest of the uterine cavity, except for the site of implantation. Therefore, in the context of fertilization, the decidua capsularis is the correct answer.
