three parts: the outer ear that contains the ear canal‚ the middle ear comprised of the ear drum and the small auditory bones‚ and the inner ear containing the cochlear and associated nerves. Sound is perceived in the brain through a mechanism that transforms auditory information encoded in the vibrations of the eardrum to electronic pulses that becomes transmitted through the auditory nerves in the brain. The cells that stimulate the nerve fibers and transduce the vibrational signal to electrical

1) Explain how prolonged exposure to loud noise is likely to cause deafness? Sound waves enters through your ear and travels through a narrow passage called ear canal‚ which then leads to your ear drums. Then the ear drums vibrate from the incoming sound waves and sends these sound vibrations to your three tiny bones called malleus‚ incus‚ and stapes. When the sound vibration hits the fluid movement in the cochlea of the inner ear. An elastic partition goes through the cochlea‚ which starts from

fluid-filled‚ snail-shaped cochlea purpose is to translate incoming sound waves into electrical signals so that the brain can understand its surroundings. The cochlea which is a Latin word for snailed-shell is a coiled‚ tapered tube containing the auditory branch of the inner ear. Its core component is the Organ of Corti‚ that is a cellular layer sitting on top of the basilar membrane for the sensory organ of hearing. The tube of the cochlea is divided into three chambers (upper‚ middle‚ and lower)

surgically-implanted and external component used to simulate natural hearing. This device is used to treat people with severe and profound hearing loss. The implanted component is placed under the skin‚ behind the patient’s ear‚ and connected to the auditory nerve of the brain. The Cochlear Implants are designed to receive sounds and convert them into electrical signals that bypass the damaged nerves‚ allowing the brain to interpret the electrical signals. How has the use of Cochlear Implant technology

The first is the physical damage to her brain and auditory system. Malala’s doctors were able to help with the brains amazing ability to heal‚ by removing part of her skull to stop the pressure her brain was inflicting on itself. Once the swelling was down on her brain‚ Malala’s missing piece of her skull was

levels above 110 decibels strip insulation from nerve fibres carrying signals from the ear to the brain. Loss of the protective coating‚ called myelin‚ disrupts electrical nerve signals. The same process‚ this time due to an attack from the immune system‚ damages nerves in the brain and results in MS. Loud noises are well known to lead to hearing problems such as temporary deafness or tinnitus (ringing in the ears). But this is the first time scientists have been able to identify the underlying
