Placenta previa occurs when the placenta develops in such a way that it covers the cervix, either partially or completely. This condition can lead to complications during labor, as it can obstruct the birthing canal, posing risks for both the mother and the baby. It is essential to diagnose placenta previa through imaging techniques such as ultrasound, as it requires careful management during pregnancy.

The other conditions relate to different placental issues: one involves early detachment from the uterine wall, another refers to abnormal implantation into the uterine muscle, and the last one describes a rarer scenario where the placenta develops outside of the uterus entirely. Each of these has different implications and requires different clinical approaches, but they do not describe placenta previa.
