allantois - a large sack that holds some of the embryo's waste. It is located near the far end (the posterior) of the embryo, close to the leg buds.
brain - the developing brain takes up much of the head area (at the anterior) of the embryo.
eye - at this point in development, the eye consists of an eye cup and lens, and is located near the brain.
heart - the developing heart is above (anterior to) the wing buds and below (posterior to) the head.
leg bud - the beginning of the development of the of the legs are small bumps of tissue located just above (anterior to) the tail bud.
spinal cord - the developing spinal cord runs through the length of the embryo, from the brain to the tail.
tail bud - the beginning of the development of the of the tail is located at the far end (the posterior) of the embryo.
wing bud - the beginning of the development of the wings are small bumps of tissue located in the mid-section of the embryo.
