The ear is divided into three intercon-necting sections: external, middle and inner ears (Fig 1). While the external and middle ears are mainly concerned with the trans-mission of sound, the inner ear contains the cochlea – often called the organ of hearing – and also houses the body’s organ of balance.
Outer Ear. • The visible part of the ear is called the Pinna or the Auricle. The pinna is made of cartilage. • The outer ear is concerned with the transmission of sound. • The outer ear consists of the Pinna, the ear canal and the outer layer of the eardrum, also called the Tympanic membrane.

Anatomy of the Ear. & Glossary of Terms. By Brian Keith, BS, Habib Rizk, MD. OVERVIEW. There are three anatomical components to the human ear: the external, middle, and inner ear. The inner ear is a complex system found within a hollow cavity of the temporal bone of the human skull known as the bony labyrinth.
The Outer Ear. The pinna, also called the auricle, is part of the outer ear and the most visible portion (Figure 4-2). Its major function is to capture and direct sound waves into the ear canal. It also helps localize the direction of sounds.
2. Structure and physiology of outer ear The outer ear comprises the pinna and the auditory canal both of which transmit the focused sound signal on the tympanic membrane which separates the outer ear and middle ear. For functional hearing, proper development of the outer ear is essen-tial.
