Which of the Following is True of Implantation

Question

Which of the following is true of implantation?
A) It is called conception.
B) It is divided into trimesters.
C) It is stimulated by FSH and LH.
D) It occurs within the uterus.

Accepted Answer

Implantation occurs within the uterus, specifically in the endometrium (lining of the uterus), where the fertilized egg attaches and begins to develop. Conception refers to the fusion of the sperm and egg to form a zygote, which occurs in the fallopian tube. Trimesters refer to the three-month periods of pregnancy after implantation has occurred. FSH and LH are hormones involved in ovulation and the menstrual cycle, but not directly in implantation.
