ARTICULATION COCHLEARIS Meaning and
Definition
-
Articulation cochlearis refers to the main functional component of the cochlea, which is a spiral-shaped, fluid-filled structure located in the inner ear. The cochlea is responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. Within the cochlea, there are three main chambers: the scala vestibuli, the scala media, and the scala tympani. The scala media contains the organ of Corti, which is key to the process of hearing.
The articulation cochlearis is the delicate point where the scala vestibuli and the scala tympani meet and communicate. The term "articulation" in this context refers to the junction or point of connection between two chambers or structures.
This crucial connection allows sound waves to enter the cochlea through the oval window, located in the scala vestibuli, and propagate through the fluid-filled chambers. As the sound waves reach the articulation cochlearis, they cause vibrations and displacement of the basilar membrane, which supports the sensory hair cells of the organ of Corti.
These hair cells are responsible for initiating the conversion of sound waves into electrical signals. The articulation cochlearis plays a vital role in this process, ensuring the transfer of sound energy from the scala vestibuli to the scala tympani, ultimately enabling the brain to perceive and interpret different frequencies and intensities of sound.
Overall, the articulation cochlearis is a pivotal anatomical feature within the cochlea that facilitates the transmission and processing of auditory information, contributing to the sense of hearing.

Etymology of ARTICULATION COCHLEARIS
The term "articulation cochlearis" is a Latin expression that can be broken down into two parts: "articulation" and "cochlearis".
1. "Articulation": This word comes from the Latin term "articulatio", which means "a joint" or "a connection". It is derived from the verb "articulare", meaning "to divide" or "to separate". In anatomy, "articulation" refers to the joint or connection between two bones.
2. "Cochlearis": This word is derived from the Latin term "cochlea", which translates as "snail shell" in English. It refers to the spiral-shaped, fluid-filled structure in the inner ear responsible for converting sound waves into electrical signals that can be interpreted by the brain.
