A child is brought to the speech therapist because she does not pronounce high-pitched sounds (like-s). if it is determined that the spiral organ of corti is the source of the problem, which region of the organ would be defective? is this conduction or sensorineural deafness?

The proximal end of the organ of Corti, close to the oval window.

Sensorineural deafness

Explanation:

The organ of Corti is also knowns as the spiral organ.It is the organ used for hearing and it is very receptive.It is located in the mammalian cochlea and it is the most likely organ to be affected in this case. The proximal end of the organ of Corti, close to the oval window is the affected part.

The most common kind of hearing impairment, sensorineural hearing loss is the major cause of the reduction of function in the organ of Corti.
