How do sound vibrations reach the cochlea when conduction deafness is present?
Sound is conducted to the receptors of the ear through vibrations of the skull bones. This is because in conduction deafness the ossicles are fused such as the stapes foot plate which can fuse to the oval window, and ossicles can fuse to oneanother from overgrowth of bony tissue. Vibrations arent specific this way and detailed so vibrations are picked up by larger surrounding bones which becomes distorted sound.
What is the difference between conduction deafness and perceptive deafness?
Conductive deafness is when the sound waves are prevented from reaching the inner ear. It can be because of wax in the outer canal, fluid inside it, or the tiny bones in the ear have seized up. With perceptive deafness, sound waves can reach the inner ear, though it is a disease of the nerves leading to the brain or a condition affecting the function of the inner ear. Most cases of deafness fall into the category of conductive and perceptive deafness, though other cases of deafness are as simple as the result of old age.
Where do sound messages go after they reach the cochlea?
eustachian tube
Why the sun's heat not reach the earth by conduction or conviction?
The sun's heat reaches the Earth through radiation, not conduction or convection. Radiation is the transfer of heat energy in the form of electromagnetic waves, such as light and infrared radiation, which can travel through the vacuum of space to reach us. Conduction and convection require a material medium, which is not present in the vacuum of space.
Nerve fibers send an impulse to the brain when the waves reach the?
Cochlea.
What attaches the stirrup to the cochlea?
The stirrup is attached to the cochlea via the oval window. When vibrations from sound waves reach the stirrup, they are transmitted through the oval window into the fluid-filled cochlea, stimulating the hair cells responsible for hearing.
What is the present tense of the word reach?
I/you/we/they reach. He/she/it reaches. The present participle is reaching.
Conduction of sound from the middle ear to the internal ear occurs via vibration of the?
Conduction of sound from the middle ear to the internal ear occurs via vibration of the oval window, which is connected to the stapes bone. When sound waves reach the oval window, they cause vibrations that travel through the fluid-filled cochlea in the inner ear, stimulating the hair cells responsible for converting sound waves into electrical signals.
What is the present tense of reach?
I/you/we/they reach. He/she/it reaches.
What is the present participle of reach?
The present participle is reaching.
Why can't the suns heat reach us by conduction or convection?
because there is no medium, conduction and convection need medium to spread through, they cannot spread through vacuum.
What happens to sound when it reaches the cochlea?
When sound waves reach the cochlea, they create pressure changes in the fluid-filled structure. This causes the basilar membrane within the cochlea to vibrate, stimulating hair cells located on the organ of Corti. These hair cells convert the mechanical vibrations into electrical signals, which are then transmitted to the brain via the auditory nerve, allowing us to perceive sound.
