Development of the External Ear

Images of the lateral view of the human embryonic head from week 5 (stage 14) through to week 8 (stage 23) showing development of the auricular hillocks (tubercles) that will form the external ear.

The adult ear is also shown indicating the part of the ear that each hillock contributes. Images are not to scale.
