In the organ of corti, what membrane is attached to the hair cells

Expert Solution

In the organ of corti tectorial membrane is attached to a hair cells.

Organ of corti is the hearing or receptor organ present in the mammalian cochlea in the inner ear.

Here the auditory signals are converted into electrochemical signal , the transduction of auditory signal occurs by vibrations of structure of inner ear causing displacement of cochlear fluid and movement of hair cells in organ of corti to produce electrochemical signals.

Organ of corti in the cochlea in the inner ear located between vestibular duct and tympanic duct produces mechanosensory cells called hari cells.

They are 3 row of outer and 1 row of inner they contains a cillia like structure of stereocilia and attachs the tectorial membrane to hair cells and also basilar membrane is present this occurs in the Scala media.

Here the process of transduction of signal auditory to electrochemical occurs which comes through hearing enters to auditory canal then to tympanic membrane goes in internal ear and then there process occurs.

And these two tectorial and basillar membrane takes part in transduction process of signals.

A group of bird embryos was studied to see if the hair cells in cochlea were able to regenerate after trauma. The first group of bird embryos was treated with growth factors similar to brain-derived neurotrophic factor molecules. The second group of bird embryos had specialized growth genes introduced into their genomes through a virus. The third group was untreated and left to develop without growth factors and gene therapy. The total number of hair cells per cochlea was determined...
