what are the parts and function of human ear?

There are three parts of the ear that work together to pass noise from external sources through your ear to your brain for information processing. The three sections are known as; the inner ear, the middle ear, the outer ear. The inner ear is made up of the cochlea, the auditory nerve and the brain.

The inner ear (also called the labyrinth) contains 2 main structures — the cochlea, which is involved in hearing, and the vestibular system (consisting of the 3 semicircular canals, saccule and utricle), which is responsible for maintaining balance.

Acoustic Senses The ears of a bony fish function in equilibrium, detecting acceleration, and hearing. There are no external openings to the ears. Sound waves travel through soft tissue to the ears. (A fish's soft body tissue has about the same acoustic density as water).

The component parts of the membranous labyrinth are the three semicircular ducts, each with a sense organ for rotational movement; the cochlear duct, with the sense organ for sound vibrations, and in the vestibule, the utricle and saccule, with their two sense organs for linear movement.

The visible part of the outer ear is called the pinna, or auricle. The pinna, with its grooves and ridges, along with the ear canal provide a natural volume boost for sounds in the 2000-3000 Hz frequency range, where we perceive many consonant sounds of speech.

Inner ear, also called labyrinth of the 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.

Middle ear. The middle ear is located between the external and inner ear. It is separated from the ear canal of the outer ear by the tympanic membrane (the eardrum). The middle ear functions to transfer the vibrations of the eardrum to the inner ear fluid.

The outer ear includes the pinna and the external auditory meatus, the ear canal. These focus sound onto the tympanic membrane, which begins the middle ear. The air-filled middle ear contains three tiny bones, the ossicles (malleus, incus, and stapes), that transmit vibrations of the tympanic membrane to the inner ear.

The ear is a sensory organ that picks up sound waves, allowing us to hear. It is also essential to our sense of balance: the organ of balance (the vestibular system) is found inside the inner ear. It is made up of three semicircular canals and two otolith organs, known as the utricle and the saccule.

The utricle is one of two "otolithic organs" in the human ear, the utricle and saccule. On the diagram above, the utricle are located in the vestibule, between the semicircular canals (5), and the cochlea (9). This figure shows a closeup of the inner ear.

The wavelengths of sound frequencies audible to the human ear (20 Hz–20 kHz) are thus between approximately 17 m and 17 mm, respectively.

The ears, nose, and throat are located near each other and have separate but related functions. The ears and nose are sensory organs, which are necessary for the senses of hearing, balance, and smell.

The major task of the ear is to detect, transmit and transduce sound. Another very important function of the ear is to maintain our sense of balance.
