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.
16 cze 2022 · The human ear is divided into three parts: the outer, middle, and inner ear. Defects in outer and middle ear can cause conductive hearing loss, while the defective inner ear may lead to sensorineural hearing loss. So, it is important to study the structure and physiology of the human ear.

As the anatomy and physiology of the ear has been covered in numerous texts in great detail, it will not be covered here in depth. Instead, the emphasis in the following is on coarse-grained com-ponents and functions of the human auditory system that are relatively uncontroversial, up-to-date, and informative for a high-level analysis.
24 lip 2023 · Ear Anatomy. This illustration shows the anatomic relationships between the helix, antihelix, auricle, tympanic membrane (TM), malleus, incus, stapes, round window, semicircular canals, cochlea, cochlear nerve, and eustachian tube (ET).
The external ear also assists in locating a sound’s origins, and functions to amplify sounds with frequencies around 3 kHz, a figure within the frequency range of human speech [2].
