Outer ear - catches sound in stereo
Eardrum - vibrates to sound
Middle ear - transducer (from big motion to small motion)
Inner ear - original sound detector, converts motion of liquid to nerve impulses
Outer Ear:
- Pinna (also called auricle): It is outer most (and visible) portion of ear. Its external parts are wide while inner portion is narrow. Because of its shape it act as a funnel (collects the sound and directs it through ear canal to ear drum).
- Ear canal (auditory canal): It contains sebaceous glands which secrete ear wax (cerumen) for lubrication of ear.
- Eardrum (tympanic membrane): It is thin membrane located at the end of outer ear. It carries the sound towards middle ear.
Middle Ear
It consists of three ear bones or ossicles (malleus, incus and stapes). These ossicles transmit sound to the inner ear.
- Malleus (also called hammer): It is hammer like ossicle. Its one end is attached to ear drum while other is connected with incus.
- Incus (anvil): It is anvil shaped bone, attached with malleus and stapes.
- Stapes: stirrup shaped bone attached to incus and oval window or vestibular window (membrane covered opening between middle ear and inner ear).
Inner ear
It contains cochlea, vestibule and semicircular canals.
- Cochlea: It is coiled portion and auditory portion of inner ear.
- Semi-circular canal: Three fluid filled canals horizontal semi-circular canal, posterior semi-circular canal and anterior semi-circular canal are called semi-circular canals.
The fluid inside these canals is called endolymph. The dilation at one end of canal is called ampulla. Ampulla contains Cupula and hair cells. Semi-circular canals are responsible for body balance and detect direction of rotation of head.
- Vestibule: It is located between the semi-circular canals and cochlea. Its anterior and inferior part has several minute holes for the passage of filaments of acoustic nerve (auditory nerve) to saccule. Saccule detects the motion of head when it moves vertically. At the upper and back of vestibule a structure called utricle detects the degree of tilt movement of head.
The ear has three main parts: the outer ear, middle ear, and inner ear. The outer ear collects sound waves and directs them to the middle ear. The middle ear contains the eardrum and three small bones that amplify sound vibrations. The inner ear has the cochlea, which converts sound vibrations into electrical signals that are sent to the brain for interpretation.
The parts of the ear that function in static equilibrium are the utricle and the saccule, which are located in the vestibule of the inner ear. These structures contain specialized sensory cells and are responsible for detecting the position of the head with respect to gravity. They help maintain balance and stability when the body is not in motion.
The different Parts of the Human EarThe three major parts of the human ear are the outer ear, the middle ear and the inner ear.Outer Ear: The outer ear consists of the following two parts:Ear Flap (Pinna)Ear Canal (Meatus)Middle Ear: consists of the following parts:Eardrum -HammerAnvil (Incus)Stirrup (Stapes)Inner Ear (Labyrinth): The inner ear comprises the following parts:CochleaSemicircular Canals -Auditory Nerve
The ear and sinus are connected through the Eustachian tube, which helps regulate pressure in the middle ear. Issues in the sinuses, such as infections or inflammation, can affect the Eustachian tube and lead to ear problems like ear infections or hearing issues. Overall, the health of the ear and sinuses are interconnected and can impact each other's functions.
The ear and sinus are connected through the Eustachian tube, which helps regulate pressure in the ear. Issues in the sinus, such as congestion or infection, can affect the Eustachian tube and lead to ear problems like ear infections or hearing issues. This connection highlights how the anatomy of the ear and sinus can impact each other's functions.
Another name for ear wax is cerumen. This is has the function of cleaning the inner parts of the ear, lubricating and also offering a layer of protection among other functions.
The three main parts of the ear are the outer ear, middle ear and the inner ear. The outer ear's function is to funnel or pass sound waves through the ear to the middle ear. The middle ear's function is to protect the inner ear from damaging sounds. In the inner ear, sound waves are converted into nerve impulses which are transmitted to the brain to be interpreted. The inner ear also serves as the main organ of balance for the body.
