The modiolus is a conical shaped central axis in the cochlea. The modiolus consists of spongy bone and the cochlea turns approximately 2.75 times around the central axis in humans. [1] The cochlear nerve, as well as spiral ganglion is situated inside it. The cochlear nerve conducts impulses from the receptors located within the cochlea.

The modiolus is the conical central axis or pillar of the cochlea.Its base is broad, and appears at the bottom of the internal acoustic meatus, where it corresponds with the area cochleæ; it is perforated by numerous orifices, which transmit filaments of the cochlear division of the acoustic nerve; the nerves for the first turn and a half pass ...

2021年11月17日 · The modiolus (plural: modioli) is part of the cochlea and is a conical-shaped structure that consists of spongy (porous) bone located in the center of the cochlea and contains the spiral ganglion. The spiral lamina projects from the modiolus.

2025年1月16日 · The modiolus is located within the cochlea, which is a spiral-shaped structure that is found in the inner ear. The cochlea is responsible for converting sound waves into electrical signals that can be interpreted by the brain.

2016年6月5日 · The core of the cochlea is the modiolus, which is highly porous bone that allows passage of auditory nerve fibers as they travel from the internal auditory meatus to the hair cell synapse. Extending from the modiolus into the osseous labyrinthine space is a bony shelf, or the osseous spiral lamina.

The cochlea is the part of the inner ear involved in hearing. It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.75 turns around its axis, the modiolus.

2023年10月30日 · The 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.

2024年7月29日 · The cochlea is a shell-shaped spiral that turns between two-and-a-half and two-and-three-quarters times around the modiolus (a central column of porous bone). The spiral of the cochlea is separated by the osseous spiral lamina and consists of the scala tympani (lower portion), scala media and scala vestibuli (upper portion).

The modiolus is the conical axis of the cochlea. The modiolus forms the medial wall of the spiral canal. The spiral canal is hollowed out for housing the cochlear nerve (CN VIII).

2024年4月26日 · Moderate-to-profound sensorineural hearing loss in humans is treatable by electrically stimulating the auditory nerve (AN) with a cochlear implant (CI). In the cochlea, the modiolus presents a porous bony interface between the CI electrode and the AN.
