The ear is anatomically divided into three main sections: the outer ear, the middle ear, and the inner ear. Each section contains distinct components that contribute to the overall process of hearing.

Physical Structures of the Ear

The outer ear is the most external section of the auditory system, which includes the visible pinna, the auditory canal that channels sound inward, and the tympanic membrane (eardrum) at its end.

Outer Ear

The middle ear is the central section of the ear, situated between the eardrum and the inner ear. It contains three tiny bones collectively known as the ossicles: the malleus (hammer), incus (anvil), and stapes (stirrup).

Middle Ear

The inner ear is the innermost part of the ear. It contains the semi-circular canals, which are involved in balance and the vestibular sense, and the cochlea, which houses the sensory cells for hearing.

Inner Ear

The process of hearing involves three sequential functions: (1) collecting and channeling sound waves, (2) amplifying the vibrations from these waves through a mechanical system, and (3) converting the amplified vibrations into neural signals for the brain. Which option correctly attributes these functions to the three main anatomical sections of the ear?
