The cochlea is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25,000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain The cochlea is attached to the stapes through the oval window. The oval window is located at the beginning of a fluid-filled tube within the cochlea called the scala vestibuli. The scala vestibuli extends from the oval window, travelling above the cochlear duct, which is the central cavity of the cochlea that contains the sound-transducing.

Is at the boundary between the middle ear and inner ear., causing vibrations to pass into a coiled, fluid filled tube, known as the Cochlea The cochlea is a A fluid filled tube in which sound waves trigger nerve from PSYCH 101 at Arizona State Universit The cochlea is a coiled, fluid-filled tube that is split into three chambers by two membranes, Reissner's membrane and the basilar membrane (Fig. 53-4) The inner ear structure called the cochlea is a snail-shell like structure divided into three fluid-filled parts. Two are canals for the transmission of pressure and in the third is the sensitive organ of Corti, which detects pressure impulses and responds with electrical impulses which travel along the auditory nerve to the brain

This action is passed onto the cochlea, a fluid-filled snail-like structure that contains the organ of Corti, the organ for hearing. It consists of tiny hair cells that line the cochlea. These cells translate vibrations into electrical impulses that are carried to the brain by sensory nerves The lengthwise partition that divides most of the cochlea is itself a fluid-filled tube, the third duct. This central column is called the cochlear duct. Its fluid, endolymph, also contains electrolytes and proteins, but is chemically quite different from perilymph The cochlea is a fluid-filled duct in the temporal bone that in humans has a length of ∼35 mm and is coiled for 2 3 4 turns. The cochlear duct is subdivided into three compartments ( scala vestibuli , scala media, and scala tympani) by two membranes: the basilar membrane, which separates scala tympani from scala media, and Reissner's membrane. The vestibular system in each ear consists of a complex series of passageways and chambers within the bony skull. Within these passageways are tubes (semicircular canals), and sacs (a utricle and saccule), filled with a fluid called endolymph. Around the outside of the tubes and sacs is a different fluid called perilymph When sound waves hit the ear drum, tiny bones in the ear transmit the vibrations to the fluid of the cochlea, where they travel along a tube that winds into a spiral. The tube's properties gradually change along its length, so the waves grow and then die away, much as an ocean wave traveling towards the shore gets taller and narrower before.

Cochlea: Anatomy, Function, and Treatmen

The 3 semicircular canals are loop-shaped tubes in the inner ear. They're filled with liquid and lined with fine hairs, just like in the cochlea, except these hairs pick up body movements. a physicist examining the mammalian cochlea as a fluid-filled tube in which mechanics are dominated by viscous damping might find this counterintuitive. Equally irrational is the concept of using a gel-like, energy-dissipating tecto-rial membrane that covers all the sensory cells (Figure 1) to transmit energy in the cochlea. From a physics perspec The cochlea is a bony tube, filled with perilymph in which floats the endolymph filled membranous labyrinth. This separates the scala vestibuli from the scala media.
