Structure, parts and function of human ear
The ear is the organ of hearing and, in mammals, balance. In mammals, the ear is usually described as having three parts—the outer ear, the middle ear, and the inner ear. The outer ear consists of the pinna and the ear canal.

Outear includes the pinna (also called auricle), the ear canal, and the very most superficial layer
of the ear drum (also called the tympanic membrane). this portion of the ear is not vital for
hearing. The pinna only helps to direct sound through the ear canal to the Middle ear (eardrum).
Middle:The middle ear behind the ear drum (tympanic membrane), includes the three ear bones
or ossicles: the malleus (or hammer), incus (or anvil), and stapes (or stirrup). The opening of the
Eustachian tube is also within the middle ear. The tympanic membrane uses sound energy strikes
the tympanic membrane and is concentrated to the smaller footplate. and articulating ear ossicles
lead to an increase in the force applied to the stapes footplate then to the malleus.
Inner ear: The inner ear includes both the organ of hearing (the cochlea) and a sense organ
labyrinth or vestibular apparatus.
Function: When sound strikes the ear drum, transferred to the footplate of the stapes, which
presses to cochlea. The fluid inside this duct flows against the receptor cells of the Organ of
Corti,which stimulate the spiral ganglion, and pass information through the auditory portion of
the brain that is eighth cranial nerve.

Answer :
The outer ear
Pinna
Ear canal
The Middle Ear
Tympanic Membrane
The tympanic membrane or eardrum serves as a divider between the outer ear and the middle
ear structures. It is gray-pink in color when healthy and consists of three very thin layers of
living tissue.
The eardrum is very sensitive to sound waves and vibrates back and forth as the sound waves
strike it.
Middle Ear Cavity
The middle ear cavity is located in the mastoid process of the temporal bone. The middle ear
cavity is actually an extension of the nasopharynx via the eustachian tube.
Eustachian Tube
The eustachian tube acts as an air pressure equalizer and ventilates the middle ear. When the air
pressure between the outer and middle ear is unequal, the eardrum is forced outward or inward
causing discomfort and the ability of the eardrum to transmit sound is reduced.
Ossicular Chain
The middle ear is connected and transmits sound to the inner ear via the ossicular chain. The
ossicular chain amplifies a signal approximately 25 decibels as it transfers signals from the
tympanic membrane to the inner ear.
THE INNER EAR
The inner ear is composed of the sensory organ for hearing—the cochlea, as well as for
balance—the vestibular system. The systems are separate, yet both are encased in the same bony
capsule and share the same fluid systems.
Vestibular or Balance System
The balance part of the ear is referred to as the vestibular apparatus. It is composed, in part, of
three semicircular canals located within the inner ear. The vestibular system helps to maintain
balance, regardless of head position or gravity, in conjunction with eye movement and
somatosensory input. The semicircular canals are innervated by the VIIIth cranial nerve.
Cochlea
The hearing part of the inner ear is the cochlea. The cochlea is spiral-shaped, similar to the
shape of a snail.
The cochlear duct contains the Basilar membrane upon which lies the Organ of Corti. The Organ
of Corti is a sensory organ essential to hearing. It consists of approximately 30,000 finger-like
projections of cilia that are arranged in rows. These cilia are referred to as hair cells. Each hair
cell is connected to a nerve fiber that relays various impulses to the cochlear branch of the VIIIth
cranial nerve or auditory nerve.
The apical portion of the basilar membrane (the most curled area of the cochlea) transfers lower
frequency impulses. The basal end relays higher frequency impulses.
The VIII cranial nerve (VIII C.N.) or auditory C.N. carries the impulses generated from the
Organ of Corti to the brainstem. From the brainstem, nerve pathways extend through numerous
nuclei to the cerebral cortex in the temporal lobes of the brain.

The human ear has three main divisions - the outer, middle, and inner ear. The outer ear collects sound waves and directs them through the auditory canal to the eardrum. In the middle ear, three small bones transmit vibrations from the eardrum to the inner ear. The inner ear contains the cochlea for hearing and semicircular canals for balance. In the cochlea, vibrations are transmitted through fluid and sensed by hair cells, sending signals to the brain. The semicircular canals contain fluid and hair cells that sense head movement and maintain balance. The ear supports both hearing by detecting sound vibrations and balance by sensing body motion.
Anatomy of ear
The ear has three main regions - the external, middle, and inner ear. The external ear collects sound waves and channels them through the ear canal to the eardrum. The middle ear contains three small bones called the ossicles that convey vibrations through the oval window to the inner ear. The inner ear houses receptors for both hearing and balance, including the cochlea which contains hair cells that detect sounds and transmit signals to the auditory nerve.

The ear is divided into three parts - outer, middle, and inner. The outer ear collects sound waves and transmits them through the auditory canal to the eardrum. In the middle ear, the eardrum vibrates from variations in sound pressure and transmits vibrations through a series of tiny bones called ossicles. The ossicles amplify vibrations and transmit them to the inner ear, where fluid-filled cochlea converts them into nerve signals for the brain to interpret sounds.
Physiology of Hearing-1.pptx
The document provides information about the physiology of hearing. It discusses the anatomy and functions of the external ear, middle ear, and inner ear. The three parts summarize as follows:
1) The external ear collects sound waves and channels them through the external auditory canal to the middle ear. The middle ear contains three small bones called ossicles that transmit vibrations from the tympanic membrane to the inner ear.
2) The inner ear houses the cochlea, which contains the organ of Corti that converts sound wave vibrations into nerve impulses. The organ of Corti contains hair cells that detect different sound frequencies along the basilar membrane.
3) Hair cells in the inner
Human Ear
The document discusses the structure and function of the human ear. It is divided into three main parts:
1. The external ear collects sound waves and channels them through the auditory canal to the eardrum.
2. The middle ear contains three small bones that transmit vibrations from the eardrum to the inner ear.
3. The inner ear contains the cochlea, which converts sound waves into nerve signals that are sent to the brain, allowing us to perceive sound. The inner ear also contains semicircular canals that help maintain balance.
Human ear
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).
Hearing and Equilibrium
The ear is divided into three main sections - the outer, middle and inner ear. The outer ear collects sound waves and directs them to the eardrum. The middle ear contains three small bones that transmit vibrations from the eardrum to the inner ear. The inner ear contains the cochlea, which converts sound waves into electrical signals perceived as sound. It also contains organs that sense body movement and position, maintaining equilibrium.
Hearing
The document summarizes the anatomy and function of the human ear. It describes the three main parts of the ear - the outer, middle, and inner ear. The outer ear collects sound waves and directs them through the ear canal. The middle ear contains three small bones that transmit sound vibrations to the inner ear. The inner ear contains structures for both hearing and balance, including the cochlea for hearing and semicircular canals and otolith organs for balance. Hair cells in the inner ear transduce mechanical vibrations into neural signals that are sent to the brain.

Ear Anatomy & Physiology
The document discusses the anatomy and physiology of the human ear. It describes the ear as having three main parts: the outer, middle, and inner ear. The outer ear collects sounds and directs them through the external auditory canal to the tympanic membrane. The middle ear contains three small bones called ossicles that transmit vibrations from the tympanic membrane to the inner ear. The inner ear converts these vibrations into neural signals for hearing and maintains balance. The cochlea and vestibular system within the inner ear work together to provide hearing and equilibrium.
Anatomy and physiology_of_the_ear
The document describes the anatomy and physiology of the human ear. It discusses the main components of the hearing mechanism, including the outer, middle and inner ear, as well as the central auditory nervous system. Sound travels through the outer ear canal to the tympanic membrane, which vibrates and converts sound waves to mechanical energy. The ossicular chain amplifies these vibrations and passes them to the inner ear fluids and structures, like the cochlea, which converts them to electrical signals sent by the auditory nerve to the brain for perception and analysis of sound.

- 2. Humans are provided with two important organs for sensing information carried by waves--- the ears and the eyes. The ear is the organ for hearing. It is divided into three parts: Outer Ear (pinna/auricle,auditory canal) Middle Ear (eardrum, ossicles, eustachian tube) Inner Ear (cochlea, vestibule and semicircular canal)
- 3. PARTS OF THE EAR
- 4. THE HUMAN EAR IS DIVIDED INTO THREE SECTIONS.
- 5. THE OUTER EAR Picture a satellite dish that collects radio waves. The outer ear is similar! The curved formation on the outside ( the pinna) helps funnel sound down the ear canal to the eardrum.
- 6. THE OUTER EAR Pinna (auricle)- receives sound waves that travel though the auditory canal or ear canal. Auditory canal (ear canal)- acts as a funnel with an approximate length of 2.5cm and leads to the ear drum. - also protects the eardrum from shock and intrusion by external objects.
- 7. THE MIDDLE EAR The middle ear transfers the energy of a sound wave by vibrating the three bones found there.
- 8. THE MIDDLE EAR Eardrum- is a cone-shaped piece of skin about 10mm wide. - it is very sensitive - even the slightest pressure variation will cause it to vibrate. - separates the outer ear from the middle ear
- 9. Ossicles- smallest bones in the body eardrum malleus (hammer)- long handle attached to the - a tiny bone that passes vibrations from the eardrum to the anvil. incus (anvil)- a tiny bone that passes vibrations from the hammer to the stirrup. Stapes (stirrups)- a tiny, U-shaped bone that passes vibrations from the stirrup to the cochlea. -This is the smallest bone in the human body (it is 0.25 to 0.33 cm long).
- 10. BONES OF THE MIDDLE EAR These are the smallest bones in your body. Hammer Anvil Stirrup Eardrum
- 11. Eustachian tube - a tube that connects the middle ear to the back of the nose; it equalizes the pressure between the middle ear and the air outside.
- 12. THE INNER EAR Two main parts: Cochlea Auditory Nerve
- 14. THE INNER EAR Cochlea- This is a spiral tube that is covered in a stiff membrane. - contains thousands of hair cells attached to the end of the organ of the auditory nerve called Organ of Corti.
- 15. COCHLEAR HAIR CELLS These tiny hairs bend because of the vibrations caused by the sound waves.
- 16. THE AUDITORY NERVE The tiny hair cells of the cochlea are set in motion by vibrations The vibrations stimulate tiny nerve cells. The nerve cells then send signals along the auditory nerve to the brain.
- 17. Auditory Nerve- These nerves receive the electrical impulses generated by the ear and pass this information up to the brain so it can be interpreted. .
- 18. Semicircular Canals- three loops of fluid- filled tubes that are attached to the cochlea in the inner ear. They help us maintain our sense of balance.
- 19. The working of human ear is in such a way that sound waves travel from the outer ear to the middle ear, which are then transmitted to the inner ear in the form of compressional waves. In the inner ear, the compressional waves are converted into electric impulses that are perceived by the brain. This way, we can hear and differentiate various sound types.
