Study Notes

Parts of the Ear

Pinna: The visible outer part of the ear that helps capture sound waves.
Auditory Canal: A tube that channels sound from the pinna to the tympanic membrane.
Tympanic Membrane: Also known as the eardrum, it vibrates in response to sound waves, converting them into mechanical energy.
Middle Ear: Contains three small bones (ossicles) that transmit sound vibrations from the tympanic membrane to the inner ear.
Eustachian Tube: A tube that connects the middle ear to the throat, helping equalize pressure on both sides of the tympanic membrane.
Cochlea: A spiral-shaped, fluid-filled structure in the inner ear responsible for converting sound vibrations into electrical signals for the brain.
Auditory Nerve: Transmits electrical signals from the cochlea to the brain for sound perception.
Malleus: Known as the hammer, this is the first ossicle that receives vibrations from the tympanic membrane.
Incus: Referred to as the anvil, it is the second ossicle that connects the malleus to the stapes.
Stapes: Known as the stirrup, this is the third ossicle that transfers vibrations to the oval window.
Ossicles: The collective term for the three bones (malleus, incus, stapes) in the middle ear that amplify and transmit sound.
Round Window: A flexible membrane that accommodates fluid movement within the cochlea, playing a role in hearing.
Oval Window: Located behind the stapes, it serves as the connection between the middle ear and the inner ear, facilitating sound transmission.
