The following article is written to provide a general understanding of the structures within the auditory system and how they function. The auditory system is comprised of three components; the outer, middle, and inner ear, all of which work together to transfer sounds from the environment to the brain. Pinna The pinna or auricle is a concave cartilaginous structure, which collects and directs sound waves traveling in air into the ear canal or external auditory meatus. Ear Canal The ear canal or external auditory meatus is approximately 1. The inner two-thirds of the ear canal is imbedded in the temporal bone. The outer one-third of the canal is cartilage. Although the shape of each ear canal varies, in general the canal forms an elongated "s" shape curve.
Human ear , organ of hearing and equilibrium that detects and analyzes sound by transduction or the conversion of sound waves into electrochemical impulses and maintains the sense of balance equilibrium. The human ear, like that of other mammals , contains sense organs that serve two quite different functions: that of hearing and that of postural equilibrium and coordination of head and eye movements. Anatomically, the ear has three distinguishable parts: the outer, middle, and inner ear. The outer ear consists of the visible portion called the auricle , or pinna, which projects from the side of the head, and the short external auditory canal , the inner end of which is closed by the tympanic membrane , commonly called the eardrum. The function of the outer ear is to collect sound waves and guide them to the tympanic membrane. The middle ear is a narrow air-filled cavity in the temporal bone. It is spanned by a chain of three tiny bones —the malleus hammer , incus anvil , and stapes stirrup , collectively called the auditory ossicles.
Ears are responsible for both hearing and maintaining the balance of the body. The ears are composed of. This structure is peculiar to terrestrial organisms. Outer ear is involved in collection, amplification and transmission of the sounds. It is composed of a pinna, an external auditory canal and an ear drum. Pinna is a cartilage tissue that has a distinct shape. It collects the sound waves and determines their source and amplifies them.

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.

The ears are organs that provide two main functions — hearing and balance — that depend on specialized receptors called hair cells. Sound waves enter through the outer ear, move into the middle ear, and finally reach the inner ear and its intricate network of nerves, bones, canals, and cells. There are three bones located in the middle ear: the incus, the malleus and the stapes. Collectively, all three bones comprise the ossicles. The malleus is the outermost and largest of the three small bones in the middle ear, and reaches an average length of about eight millimeters in the…. The human ear consists of three regions called the outer ear, middle ear, and inner ear. The oval window, also known as the fenestra ovalis, is a….
