The sensory receptors involved in hearing are called hair cells. These specialized cells are located within the spiral-shaped cochlea of the inner ear. They are responsible for converting sound waves into electrical signals that can be processed by the brain. When sound waves enter the ear, they cause vibrations in the fluid-filled cochlea. These vibrations then stimulate the hair cells, which bend and create electrical signals. These signals are then transmitted to the brain via the auditory nerve, where they are interpreted as sound.
The sensory receptors involved in hearing are called hair cells. These hair cells are located within the cochlea, which is a spiral-shaped structure in the inner ear responsible for converting sound into electrical signals that can be interpreted by the brain.
To understand how these hair cells function, let's break it down:
1. Sound waves: Sound waves are created when an object vibrates, causing air particles to compress and expand. These waves travel through the air or other mediums, such as water.
2. Outer and middle ear: The sound waves enter the outer ear, pass through the ear canal, and reach the middle ear. The middle ear consists of the eardrum and three small bones called ossicles (malleus, incus, and stapes). These bones transmit and amplify the vibrations of the eardrum.
3. Inner ear and cochlea: The amplified vibrations from the ossicles reach the inner ear, specifically the cochlea. The cochlea is filled with fluid and consists of three main chambers. The vibrations cause the fluid in the cochlea to move, stimulating the hair cells.
4. Hair cells: Within the cochlea are thousands of specialized hair cells. These cells have tiny hair-like projections called stereocilia on their surface. When the fluid in the cochlea moves due to sound vibrations, it causes the stereocilia to bend.
5. Auditory nerve: The bending of stereocilia causes ion channels to open, allowing electrical signals to be generated in the hair cells. These electrical signals are transmitted to the auditory nerve, which carries the information to the brain for processing and interpretation.
So, to summarize, the sensory receptors involved in hearing are the hair cells located in the cochlea of the inner ear. When sound waves reach the cochlea, they cause the hair cells to move, generating electrical signals that are sent to the brain through the auditory nerve.
