SULCUS SPIRALIS INTERNUS Meaning and Definition

1. Sulcus spiralis internus refers to a specific anatomical feature found within the cochlea, which is the spiral-shaped portion of the inner ear responsible for hearing. The term "sulcus" refers to a shallow groove or depression, while "spiral" refers to the cochlea's unique shape.

   The sulcus spiralis internus is a small, narrow groove located within the cochlea that runs parallel to the modiolus, a central bony core. This spiral-shaped groove is positioned between the scala media, also known as the cochlear duct, and the cochlear spiral ligament. It is involved in the formation of the organ of Corti, a vital structure for hearing.

   Inside the sulcus spiralis internus, there are several important components that contribute to the function of the cochlea. These structures include the spiral ganglion, which contains the cell bodies of the auditory nerve fibers, and the cochlear duct, which houses the sensory hair cells responsible for converting sound vibrations into electrical signals that can be interpreted by the brain.

   The sulcus spiralis internus plays a crucial role in the overall structure and function of the cochlea. It provides important support and organization for the various components involved in the process of auditory perception. Understanding the anatomy and function of the sulcus spiralis internus is crucial for comprehending the complexities of the inner ear and its role in the auditory system.

2. Internal spiral sulcus, a concavity in the floor of the ductus cochlearis formed by the overhanging labium vestibulare.
