A microCT 3D reconstruction of a 10-day-old chick embryo, as seen from the right hand side. The inner ear is depicted, with the semicircular canals (the body's balance organ) and the cochlea (which converts sound waves into electrical impulses) shown in green. The otic capsule, a cartilaginous structure surrounding the inner ear which develops into part of the sphenoid bone, is shown in blue.
