The cochlea is a portion of the inner ear that looks like a snail shell (cochlea is Greek for snail). [5] The cochlea receives sound in the form of vibrations, which cause the stereocilia to move. The stereocilia then convert these vibrations into nerve impulses which are taken up to the brain to be interpreted.
In one study, the basal turn of the cochlea was measured, and it was hypothesized that cochlear size correlates with body mass. The size of the basal turn of the cochlea was not different in Neanderthals and Holocene humans, however it became larger in early modern humans and Upper Paleolithic humans. Furthermore, the position and orientation ...
The ventral cochlear nucleus is unlayered whereas the dorsal cochlear nucleus is layered. Auditory nerve fibers, fibers that travel through the auditory nerve (also known as the cochlear nerve or eighth cranial nerve) carry information from the inner ear, the cochlea, on the same side of the head, to the nerve root in the ventral cochlear ...
The cochlear duct is part of the cochlea. It is separated from the tympanic duct (scala tympani) by the basilar membrane. [2] It is separated from the vestibular duct (scala vestibuli) by the vestibular membrane (Reissner's membrane). [2] The stria vascularis is located in the wall of the cochlear duct. [2]
The osseous spiral lamina is a bony shelf or ledge which projects from the modiolus into the interior of the bony canal of the cochlea, and, like the canal, takes two-and-three-quarter turns around the modiolus.
Sensorineural hearing loss (SNHL) is a type of hearing loss in which the root cause lies in the inner ear, sensory organ (cochlea and associated structures), or the vestibulocochlear nerve (cranial nerve VIII). SNHL accounts for about 90% of reported hearing loss.
For many Japanese Americans, the Oscar win for “Godzilla Minus One” on the same night that "Oppenheimer" won best picture symbolized much more than just a place in the halls of film excellence.
Cross-section through the spiral organ of Corti at greater magnification, showing position of the hair cells on the basement membrane. The organ of Corti is located in the scala media of the cochlea of the inner ear between the vestibular duct and the tympanic duct and is composed of mechanosensory cells, known as hair cells. [2]
