RECESSUS EPITYMPANICUS Meaning and
Definition
-
The term "recessus epitympanicus" refers to a specific anatomical feature of the middle ear that is located above the tympanic membrane. This anatomical structure is also commonly known as the epitympanic recess.
The recessus epitympanicus is a small cavity or space within the middle ear that is situated superiorly to the eardrum, or tympanic membrane. It is known for its importance in the functioning of the auditory system. This recess is surrounded by other structures of the temporal bone, such as the tegmen tympani superiorly and the scutum laterally.
Within the recessus epitympanicus, there are several critical components that are crucial for the transmission, amplification, and processing of sound waves. One such component is the ossicular chain, which includes the three small bones of the middle ear called the malleus, incus, and stapes. These bones collectively transmit vibrations from the eardrum to the inner ear, facilitating the process of hearing.
Furthermore, the recessus epitympanicus also houses the chorda tympani nerve, which is a branch of the facial nerve. This nerve is responsible for conveying taste sensations from the tongue to the brain.
Overall, the recessus epitympanicus plays a vital role in the intricate mechanisms of the middle ear, serving as a key space that houses important anatomical structures necessary for hearing and taste perception.

Etymology of RECESSUS EPITYMPANICUS
The word "recessus epitympanicus" is a combination of two Latin terms: "recessus" and "epitympanicus".
1. "Recessus" comes from the Latin verb "recedere", meaning "to recede" or "to retreat". It refers to a space or cavity that is set back or recessed from the main anatomical area. In medical terminology, "recessus" is often used to describe small cavities or recesses within various structures of the body.
2. "Epitympanicus" consists of two components: "epi", meaning "upon" or "above", and "tympanicus", which is derived from "tympanum" (eardrum) and relates to the middle ear.
