The inner ear contains the receptors for sound which convert fluid motion into action potentials that are sent to the brain to enable sound perception. The airborne sound waves must be transferred into the inner ear for hearing to occur.

Where does an action potential start?

Action potentials are generated on a part of the neuron called the 'axon hillock' - the proximal most portion of the axon.


How does your eardrum process sound?

It doesn't process anything, it is a part of a system (eardrum, 3 bones of the middle ear, and a thin part of your skull) that converts vibrations in the air into vibrations in the fluids of your inner ear. Those you can hear.


What is the part of a cell that carries action potentials away from the cell body?

The part of a cell that carries action potentials away from the cell body is called the axon. Axons are long, slender projections that transmit electrical signals, known as action potentials, to other neurons, muscles, or glands. They are essential for communication within the nervous system and can vary greatly in length and diameter. The axon is often insulated by a myelin sheath, which helps speed up signal transmission.


What part of the ear changes the sound waves that travel down your ear into vibrations?

The tympanic membrane, also known as the eardrum, is the part of the ear that converts sound waves into vibrations. When sound waves reach the eardrum, it vibrates and transmits these vibrations to the middle ear.


What are cartridge turntables used for?

Cartridge turntables are used to play records. The cartridge is the part of the turntable that converts the vibrations picked up from the record into music.


What structures carry action potentials caused by sound transduction?

Action potentials caused by sound transduction are carried by the auditory nerve fibers, which are part of the vestibulocochlear nerve (cranial nerve VIII). These nerve fibers transmit the signals from the hair cells in the cochlea to the brainstem and auditory cortex for processing.


What part of a telephone detects sound waves?

The tranducer/microphone converts the vibrations of the waves into electrical audio signals, the vibrations cause a diaphragm inside the transducer to vibrate which in turns create pulses of current that can be interpreted later as the recorded audio.


Where is information communicated along the nerves?

Information is communicated along the nerves through electrical signals known as action potentials. These action potentials travel down the length of the nerve cell and are transmitted from one nerve cell to another at specialized junctions called synapses. In this way, messages can be passed from one part of the body to another.


How does the long axon help in a nerve cell?

The axons are long so that action potentials can be sent from one part of the body to another very quickly. If instead of one long axon we had loads of individual cells there would be a much bigger delay because the action potentials would have to be converted to chemical signals very fequently and that takes time.


In which part of the ear receives the vibrations in the air?

The eardrum receives the vibrations of the air.


Part of your ear sends the message to your brain that you've heard a sound?

The cochlea


What part of the ear transmits the vibrations to the cochlea?

The eardrum
