Challenge A Anatomy Practice Test

The part described is the earlobe, the soft, fleshy lower portion of the outer ear. It lacks cartilage and is the section people commonly wear earrings in because it’s flexible and easy to pierce. The pinna (or auricle) is the entire outer ear’s cartilaginous framework, which is firmer and not the lower squishy area. The cochlea is part of the inner ear, not visible on the outside. So the best answer is the earlobe.
