The cochlear nerve then passes these impulses to the cerebral cortex and the brain interprets them, and we get to hear. The organ of corti which contains thousands of tiny hair cells, when moved, sends electrical impulses through the cochlear nerve. Cochlea is a complex part of the ear, which takes the physical vibrations caused by the sound waves and translates them into electrical information for the brain to recognize as sound. The uppermost part of the spinal column, the cervical spine is a complex structure of bones, discs, muscles, ligaments, nerves, and tendons. Then the cochlea in the inner ear conducts the sound through a fluid. The ossicles in the middle ear do the job of amplification. Before the sound waves enter the inner ear, the total pressure must be amplified. The sound waves travel first through the ear canal and vibrate the eardrum. Vestibulocochlear Nerve: It is nerve that transmits messages regarding sound and balance, from the inner ear to the brain.They play a crucial role when it comes to balancing the body. Semicircular Canals: The semicircular canals are located in the inner ear and constitute of three tiny tubes that are filled with fluid.It plays a crucial role in ensuring that the air pressure on each side of the eardrum is even. Eustachian Tube: It is a tube which connects the middle ear cavity and the pharynx.It is responsible for converting sound vibrations into nerve signals that are sent to the brain. Cochlea: Cochlea is tiny conical structure situated in the inner ear that resembles a snail shell.Eardrum/Tympanic Membrane: It is the thin membrane located between the external ear canal and the middle ear.
Both strong and delicate, the cervical spine is an incredible structure that carries the weight of your head (10-11 pounds), protects the spinal cord, supplies blood to the brain, and allows a wide range of motion, supporting your head and neck movements. These bones together are called the auditory ossicles, and their purpose is to let the sound that strikes the eardrum, further into the inner ear. The uppermost part of the spinal column, the cervical spine is a complex structure of bones, discs, muscles, ligaments, nerves, and tendons.
