What are the 3 anatomical regions of the ear?

The medical term for the outer ear is the auricle or pinna. The outer ear is made up of cartilage and skin. There are three different parts to the outer ear; the tragus, helix and the lobule. The ear canal starts at the outer ear and ends at the ear drum.

What are the functions of each part of the ear?

The ear is divided into three interconnecting sections: external, middle and inner ears (Fig 1). While the external and middle ears are mainly concerned with the transmission of sound, the inner ear contains the cochlea – often called the organ of hearing – and also houses the body's organ of balance.

What is middle ear anatomy?

The middle ear lies within the temporal bone, and extends from the tympanic membrane to the lateral wall of the inner ear. The main function of the middle ear is to transmit vibrations from the tympanic membrane to the inner ear via the auditory ossicles.
