Im stuck on the second part of question
The fluid filled organ of the inner ear has tiny (A) __________ cells that release neurotransmitters. Different sound frequencies affect different groups of these cells, and louder sounds stimulate more of these cells in a given region. This stimulation triggers nerve impulses in the (B) __________ nerve, which then carries the message to the brain.
The first answer is hair
Auditory.
Thank you I never wanted to take this class but it was mandatory and so diffrent on sophia learning
To find the answer to the second part of the question, you will need to think about the role of the hair cells in the inner ear and how they are connected to the brain.
The fluid-filled organ of the inner ear contains tiny hair cells that release neurotransmitters. These hair cells play a vital role in detecting and converting sound vibrations into electrical signals that can be sent to the brain. When sound waves enter the inner ear, they cause the fluid surrounding the hair cells to move, which in turn causes the hair cells to bend.
The bending of the hair cells initiates a chemical reaction that leads to the release of neurotransmitters. These neurotransmitters transmit the electrical signals generated by the hair cells to the auditory nerve, which is also known as the cochlear nerve.
The cochlear nerve carries these electrical signals from the hair cells to the brain for further processing and interpretation. It serves as a pathway for the transmission of auditory information from the inner ear to the brain, allowing us to perceive and understand sound.
Therefore, the answer to the second part of the question is the cochlear nerve. The stimulation of the hair cells triggers nerve impulses in the cochlear nerve, which then carries the message to the brain.
