Lesson 6 Assignment: PART TWO 1. Identify the sensory receptors in the ear. The sensory receptors in the ear are the hair cells that are found on the organ of Corti. The hair cells change the vibrations into electrical signals that are sent to the brain through the hearing nerve. 2. Explain in detail how sound waves that are amplified by the ossicles are translated into a nerve impulse in the inner ear. Sound waves that are amplified by the ossicles are translated into a nerve impulse in the inner ear because the bones in the ear act as amplifiers for each other. This means that as the sound waves travel through the ear, they become louder as they move from the malleus to the incus to the stapes. This moves sound waves from the tympanum to the inner ear. 3. Describe how continued exposure to loud noises can result in noise-induced hearing loss. The long term exposure to loud noises can lead to noise induced hearing loss because the hair cells eventually become more damaged. The louder the noise is, the more damage it does to the hair

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
