What is the spiral limbus?
The spiral limbus is a part of the organ of Corti in the inner ear. It is a thin, bony ridge that runs along the edge of the cochlea, the spiral-shaped structure that contains the organ of Corti. The spiral limbus is composed of periosteum, the type of tissue that covers the bone.
The spiral limbus has two main functions:
- It provides attachment for the tectorial membrane, a thin, gelatinous membrane that sits on top of the hair cells in the organ of Corti. The tectorial membrane plays a role in the transduction of sound waves into electrical signals that the brain can interpret as sound.
- It provides support for the outer hair cells in the organ of Corti. The outer hair cells are responsible for amplifying sound waves, which helps us to hear soft sounds more clearly.
The spiral limbus is located on the osseous spiral lamina, a bony ridge that runs along the edge of the cochlea. The osseous spiral lamina provides support for the spiral limbus and helps to keep it in place.

Conclusion
The spiral limbus is an important part of the organ of Corti. It provides attachment for the tectorial membrane and support for the outer hair cells. These structures play a role in the transduction of sound waves into electrical signals that the brain can interpret as sound. The spiral limbus is also important for amplifying sound waves, which helps us to hear soft sounds more clearly.
