- The cochlea is a fluid-filled, snail-like structure within the inner ear. It plays a vital role in hearing by containing hair cells that convert sound waves into electrical impulses1234. Key points about cochlea anatomy include:
- It is a hollow, spirally coiled chamber inside the temporal bone2.
- The cochlear canal houses a triangular membranous duct called the cochlear duct2.
- The cochlea is coiled two and one-half turns around a hollow central pillar called the modiolus3.
- It contains the sensory organ of hearing3.
- Nerve cells in the spiral ganglion project sound signals to tiny hair cells within the cochlea4.

It plays a vital role in the function of hearing rather than simply being another component of the skeletal system. The cochlea contains hair cells that convert sound waves into electrical impulses that are carried along the auditory nerve to the brain.www.verywellhealth.com/cochlea-anatomy-5069393The cochlea is a component of the labyrinth of the internal ear that is responsible for hearing. It is a hollow, spirally coiled chamber inside the temporal bone that makes 2.75 turns around its axis, which is called the modiolus. The cavity of the cochlea (cochlear canal) houses a triangular membranous duct, called the cochlear duct.www.kenhub.com/en/library/anatomy/cochleaThe cochlea contains the sensory organ of hearing. It bears a striking resemblance to the shell of a snail and in fact takes its name from the Greek word for this object. The cochlea is a spiral tube that is coiled two and one-half turns around a hollow central pillar, the modiolus.www.britannica.com/science/ear/CochleaThe cochlea, which is a spiral-shaped organ that contains fluid (perilymph and endolymph), is found in the inner ear. The cochlea houses the cell bodies of the cochlear nerve within a region called the spiral ganglion.
