Cochlear Canal, Cochlear Duct, Middle Staircase (Scala Media)

The Cochlear Canal, or Cochlear Duct, also called the Scalena Middle, is part of the cochlea of ​​the inner ear. The cochlea is a spiral canal filled with endolymph. The Canal of the Cochlea is located between the staircases of the Vestibule and Tympani - the other two parts of the cochlea.

The Cochlear Canal contains the organ of Corti, a hearing receptor organ consisting of hair cells that convert sound vibrations into nerve impulses. These impulses are then transmitted to the brain via the auditory nerve. Thus, the Cochlear Canal, or Staircase Middle, plays a key role in the perception of sound by the inner ear.
