When a tiny bone taps on the membrane of the cochlea, the fluid inside moves, stimulating the tiny hairs and triggering electrical nerve impulses.
The middle ear is encased in bone and does not associate with outside air except through the Eustachian tube. 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. The opposition of the air is greater inside The cochlea changes the mechanical vibrations from the eardrum and the ossicles into a sequence of electrical impulses. The cerumen (ear wax) prevents the entry of the foreign bodies into the ear. They also noted that the ear does indeed get larger as a person ages.Another study at Texas Tech Universit… The hair cells change the movement into electrical impulses. Typically, men’s ears are larger than women’s, according to a study in the journal Plastic and Reconstructive Surgery. Structure of Ear. Researchers also found that the average ear is about 2.5 inches (6.3 centimeters) long, and the average ear lobe is 0.74 inches (1.88 cm) long and 0.77 inches (1.96 cm) wide. Outer ear: Acoustic energy, in the form of sound waves, passes pinna, ear canal. Monday – Friday:9:00am – 5:00pm (San Luis Obispo)Monday – Thursday:9:00am – 5:00pm (Atascadero)Weekends & After-Hours:By appointment only. The human ear picks up and interprets high-frequency vibrations of air, while the sound-sensing organs of aquatic animals are designed to pick up high-frequency vibrations in water. The major task of the ear is to detect, transmit and transduce sound. Maintaining a sense of balance is another important function performed by the human ear. The ear canal, also called the external auditory meatus, is the other important outer ear landmark. The ear is an advanced and very sensitive organ of the human body. This tubular structure is normally closed, but it can be involuntarily opened by swallowing, yawning, or chewing. The eardrum, or tympanic membrane (TM), is the dividing structure between the outer and middle ear. It is mainly concerned with detecting, transmitting and transducing sound. It directs sound down the ear and helps localize sound. The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. The cochlea is a spiral-shaped membrane which is lined with over 15,000 tiny hairs and has fluid moving within it. The ear’s function is to transmit and transduce sound to the brain through the parts of the ear: the outer ear, the middle ear and the inner ear. The cochlea is arranged by frequency, much like a piano, and encodes sounds from 20Hz (low pitch) to 20,000Hz (high pitch) in humans. The motion of the three bones causes the fluid in the inner ear, or cochlea, to move. The ear can be divided into three parts, which work together, they are the outer ear, the middle ear and the inner ear.
Ears come in many shapes and sizes. The movement of the fluid in the inner ear causes the hair cells in the cochlea to bend. Three main parts of ear are: 1.External ear: it have protective function and the outer pinna directs the ear towards the sound wave.without pinna also one can hear 2.Middle ear: it consists of auditory canal and ear drum or tympanum. The major functions of the ear are to maintain the balance and equilibrium of the body and to aid in hearing capabilities.
The part of human ear involved in the function of hearing is the cochlea. The inner ear has two main structures: the semicircular canals and the cochlea. The pinna, with its grooves and ridges, provides a natural volume boost for sounds in the 2000 to 3000 Hz frequency range, where we perceive many consonant sounds of speech. Another major function of the human ear is to maintain balance of the body. The outer ear works like a funnel. The ear is an advanced and very sensitive organ of the human body. This means that there is an abundant flow of blood to the ear canal.

The inner ear is the final part of the ear, allowing us to translate sound waves into recognisable information. The ossicles translate mechanical vibrations received at the eardrum into the inner ear. Functions of External Ear: It directs sound waves towards the tympanic membrane. Functions of eardrum: Provide a funnel to a sound waves to reach among bone fragments located in the middle ear: The role of the eardrum, also called as the tympanic membrane, is always to take sound waves to bone fragments which have been found in the middle ear. The ossicles are the three tiny bones of the middle ear located directly behind the tympanic membrane. Sound waves hit the ear drum, causing it to vibrate like a drum. The inner ear is an organ located deep within the temporal bone, which is the bone of the skull on both sides of the head above the outer ear. These three bones form a connected chain in the middle ear. The different parts of the human ear that help in balancing are the semicircular canals consisting … The ear is a sensitive organ of the human body. 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 resulting functions of the ear permit the hearing of the elephant’s trumpet and the croak of the frog, as well as the voices of friends and family and the sounds of favored music. The semicircular canals do not contribute to hearing, but assist in maintaining balance as we move. When this happens, you might hear a soft popping sound. These middle ear bones mechanically amplify sound and compensate mismatched impedance. Let us have an overview of the structure and functions of the human ear.
