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.
17 Μαΐ 2024 · The outer ear, also known as the external ear or auris externa, consists of the auricle, ear canal, and eardrum. They work together to funnel sound waves from the environment to the middle and inner ear, where they are translated into nerve impulses for the brain.
The ear is structurally and functionally partitioned into three parts that are required for normal hearing: the outer inner, middle ear, and the inner ear—the latter is further divided into the vestibular labyrinth and cochlea (Figure 1). These are discussed in detail below.
