spiral ganglion
anatomy
Also known as: spiral ganglion of Corti
Quick Summary
The spiral ganglion is an aggregation of nerve cell bodies located within the modiolus of the cochlea in the inner ear. These neurons, known as bipolar cells, have two sets of fibers. The longer, central fibers form the cochlear nerve, which transmits auditory information to the brainstem. The shorter, peripheral fibers extend to the hair cells within the organ of Corti, playing a crucial role in converting sound vibrations into nerve impulses. This intricate structure is essential for the process of hearing.12
