Human ear and Physiology of Hearing 1. Pharm Amrita School of Pharmacy 2. Study of Human Ear 3. Three main parts of the Ear 5. Outer Ear Outer Ear pinna auditory canal 6. Made of cartilage and skin and shaped like a funnel. It collects and directs sounds into the ear canal.
Auditory canal Auditory canal is a tunnel or passageway that begins at the external ear and extends inward toward the eardrum. A long tube lined with hairs. It directs sounds to the eardrum. Middle Ear 8. It vibrates and transmits sound waves to the ossicles. Ossicles Made up of three small bones which is the hammer Malleus , the anvil Incus and the stirrup stapes. It intensifies the vibrations of the sound waves by 22 times before transmitting to the oval window.
Eustachian tube A narrow tube that joins the middle ear to the throat that balances the air pressure at both sides of the eardrum.
Oval window An oval-shaped, thin membrane between the middle ear and the inner ear. It transmits sound vibrations from the middle ear to the inner ear. Inner ear It consists of three tubes canals 1. Scala Vestibuli Vestibular canal 2. Scala media cochlear canal 3. The ossicles amplify the sound 22 X Tensor tymphani muscles initiates the vibrations depends upon frequency.
When the foot of the stapes moves inward against the oval window, the round window must bulge outward because the cochlea is bounded on all sides by bony walls. Vibrations of stapes and oval window displace perilymph fluid within scala vestibuli Function of Maculae Check noise levels in your surroundings to protect your ear.

The ear is the sense organ that enables us to hear. Hearing can be defined as the perception of sound energy via the brain and central nervous system. Hearing consists of two components: identification of sounds what the sound is and localisation of those sounds where the sounds are coming from. The ear is divided into three main parts — the outer ear , the middle ear , and the inner ear. The inner ear is filled with fluid. The inner ear also contains the receptors for sound which convert fluid motion into electrical signals known as action potentials that are sent to the brain to enable sound perception.
duced by the talker—human speech sounds—into neural energy that can be is defined here as the structures from the outer ear through the auditory nerve.
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 best way to describe the functioning of the ear is to describe the path which the sound waves take on their way through the ear. In the video you can see the journey of the sound waves through the ear.

The ear is the organ of hearing and, in mammals, balance.
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 pinna is a projecting elastic cartilage covered with skin. Its most prominent outer ridge is called the helix. The lobule is the soft pliable part at its lower end composed of fibrous and adipose tissue richly supplied with blood capillaries.
