Where does a fertilized egg normally implant and develop?

A fertilized egg, after successful conception, normally implants in the uterus. The uterus provides a suitable environment for the developing embryo to receive nutrients and support its growth during the early stages of pregnancy. It has a specialized lining, known as the endometrium, which thickens in preparation for potential implantation and provides the necessary conditions for embryo attachment and development.

The other areas mentioned, such as the fallopian tube, are involved in the early stages of fertilization but are not suitable for implantation. The placenta develops later in pregnancy and serves as the interface for nutrient and waste exchange between the mother and the growing fetus, but it is not the site of implantation. The cervix, while an important structure in the reproductive system, does not play a role in the implantation of a fertilized egg either. Therefore, the uterus is indeed the correct answer as the location for implantation and development of a fertilized egg.
