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]
It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.75 turns around its axis, the modiolus. [ 2 ] [ 3 ] A core component of the cochlea is the organ of Corti , the sensory organ of hearing, which is distributed along the partition separating the fluid chambers in the coiled tapered tube of the cochlea.
The organ of Corti is located in this duct on the basilar membrane, and transforms mechanical waves to electric signals in neurons. The other two sections are known as the scala tympani and the scala vestibuli. These are located within the bony labyrinth, which is filled with fluid called perilymph, similar in composition to cerebrospinal fluid.
Section through the spiral organ of Corti, magnified. The stereocilia are the "hairs" sticking out of the tops of the inner and outer hair cells.. As acoustic sensors in mammals, stereocilia are lined up in the organ of Corti within the cochlea of the inner ear.
Cross-section through the spiral organ of Corti at greater magnification. Rosenthal's canal or the spiral canal of the cochlea is a section of the bony labyrinth of the inner ear that is approximately 30 mm long and makes 2¾ turns about the modiolus, the central axis of the cochlea that contains the spiral ganglion.
But there is a range of ultra-processed foods. “Some ultra-processed foods, like protein powders or cereal, could be part of a healthy diet,” says Dena Champion, RDN, a dietitian at The Ohio ...
The spiral (cochlear) ganglion is a group of neuron cell bodies in the modiolus, the conical central axis of the cochlea. These bipolar neurons innervate the hair cells of the organ of Corti . They project their axons to the ventral and dorsal cochlear nuclei as the cochlear nerve , a branch of the vestibulocochlear nerve (CN VIII).
In March, a mother was horrified to find a pedophile symbol on a toy she bought for her daughter. Although the symbol was not intentionally placed on the toy by the company who manufactured the ...
