Using graphic animation, this video shows the step by step process for removing tonsils and adenoids, including these anatomical structures that are located in the throat.

This animation not only shows how the ear detects sound waves and converts those waves into nerve signals, but it also shows how cochlear implants work and allow patients with nerve deafness to hear.

Dental implants are artificial teeth that are anchored to bone; however if the bone is too thin, the dental implant cannot be implanted. The animation describes the bone grafting procedure that is sometimes necessary to build up the bone show that it can support a dental implant.

People hear sound waves when the ear and associated structures convert sound energy into nerve impulses. An overview of the way in which the ear "hears" is discussed along with discussion of the two main types of hearing loss: conductive hearing loss and sensorineural hearing loss.
