Anatomy & Physiology II - Special Senses Quiz

The special senses are the senses that have specialized organs devoted to them for vision hearing and balance also smell. We covered the anatomy of the organs tasked to these actions and their functions. Take the quiz below and get to learn more about the topic. All the best as you do!
