Do all animals have placentas?
The placentals include all living mammals except marsupials and monotremes. The true placenta of the placentals allows for a longer developmental period within the protection of the womb, a factor considered to have contributed to the evolutionary success of the group.

What is it called when the head is first visible?
During labor and delivery, your baby must pass through your pelvic bones to reach the vaginal opening. The goal is to find the easiest way out.

What develops first in an embryo?
Just four weeks after conception, the neural tube along your baby’s back is closing. The baby’s brain and spinal cord will develop from the neural tube. The heart and other organs also are starting to form and the heart begins to beat. Structures necessary to the formation of the eyes and ears develop.
