Each ear has three sections: the outer ear, the middle ear, and the inner ear. The outer ear is divided into two main parts: the auricle and the ear canal. The auricle is the part of the ear that is visible on the sides of the head.
Inner ear | Definition, Anatomy, Balance, & Facts | Britannica
Inner ear, part of the ear that contains organs of the senses of hearing and equilibrium. The bony labyrinth, a cavity in the temporal bone, is divided into three sections: the vestibule, the semicircular canals, and the cochlea.
Human ear - Hearing, Anatomy, Physiology | Britannica
Human ear - Hearing, Anatomy, Physiology: Hearing is the process by which the ear transforms sound vibrations in the external environment into nerve impulses that are conveyed to the brain, where they are interpreted as sounds.
Vestibular system | Definition, Anatomy, & Function | Britannica
Vestibular system, apparatus of the inner ear involved in balance. It consists of two structures of the bony labyrinth of the inner ear, the vestibule and the semicircular canals, and the structures of the membranous labyrinth contained within them.
Malleus | anatomy | Britannica
In ear bone These are the malleus, or hammer, the incus, or anvil, and the stapes, or stirrup. Together they form a short chain that crosses the middle ear and transmits vibrations caused by sound waves from the eardrum membrane to the liquid of the inner ear.
Human ear - Cochlea, Hearing, Balance | Britannica
Human ear - Cochlea, Hearing, Balance: The cochlea contains the sensory organ of hearing. It bears a striking resemblance to the shell of a snail and in fact takes its name from the Greek word for this object. The cochlea is a spiral tube that is coiled two and one-half turns around a hollow central pillar, the modiolus.

Human ear - Anatomy, Hearing, Balance | Britannica
Human ear - Anatomy, Hearing, Balance: The most-striking differences between the human ear and the ears of other mammals are in the structure of the outermost part, the auricle. In humans the auricle is an almost rudimentary, usually immobile shell that lies close to the side of the head.
Human ear - Cochlear Nerve, Auditory Pathways | Britannica
Human ear - Cochlear Nerve, Auditory Pathways: The vestibulocochlear nerve consists of two anatomically and functionally distinct parts: the cochlear nerve, which innervates the organ of hearing, and the vestibular nerve, which innervates the organs of equilibrium.
