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.

Endocrine System, Pituitary Gland

This narrated 3D animation shows how the brain drives the specialized nerve cells of the pituitary gland and, in turn, how the pituitary gland effects other endocrine glands. The feedback regulation of the endocrine system is also described.

Causes and Types of Hearing Loss

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.
