    b. False


    The spiral ganglion, formed from the primitive otocyst, is located on the cochlea's modulus (axis) and is made up of approximately 35,000 neurons in man. These bipolar neurons are of two types: type I and type II. Its peripheral extensions (dendrites) end in the spiral organ, in contact with the hair cells of which they receive information. Its central extension (axon) ends at the cochlear nuclei of the brainstem.
