The spelling of the word "recessus cochlearis" can be explained using the International Phonetic Alphabet (IPA). The first part, "recessus" is pronounced /rɪˈsɛs.ʊs/, with the stress on the second syllable. The second part, "cochlearis" is pronounced /kɒkˈliər.ɪs/, with the stress on the third syllable. The word refers to the part of the inner ear where the cochlea, a fluid-filled structure responsible for hearing, is located. Knowing how to spell and pronounce complex medical terms is important for effective communication among healthcare professionals.
Recessus cochlearis refers to a specific anatomical structure found within the inner ear, more precisely, the cochlea. The cochlea is a spiral-shaped, snail-like structure responsible for the sense of hearing. This recessus cochlearis is a section or compartment within the cochlea that plays a vital role in the transmission and processing of sound signals.
The recessus cochlearis can be described as a narrow and curved passage within the cochlea, located between the scala tympani and the scala media. These two fluid-filled chambers are integral to the functioning of the cochlea. The scala media contains a fluid called endolymph, while the scala tympani holds another fluid known as perilymph. Sound vibrations enter the cochlea through the oval window and create ripples in the fluid, triggering the activation of hair cells responsible for converting these vibrations into electrical impulses sent to the brain.
The recessus cochlearis serves as a critical region for the optimal separation of sound frequencies. It facilitates the separation and differentiation of high-frequency and low-frequency components of sound. This separation is accomplished by means of specialized structures like the basilar membrane and the specialized hair cells present in the cochlea. These cells respond to specific sound frequencies, further aiding in frequency discrimination.
Overall, recessus cochlearis is an important structural component of the cochlea that contributes to the complex process of hearing by providing an environment that supports the vital functions of sound transmission, separation of frequencies, and the conversion of sound signals into electrical impulses for interpretation by the brain.
Cochlear recess, a depression on the inner wall of the vestibule of the labyrinth, between the two limbs into which the crista vestibuli divides posteriorly; it is perforated by foramina giving passage to nerves supplying the posterior portion of the ductus cochlearis.

The term "recessus cochlearis" is derived from Latin. Here is the breakdown of its etymology:
1. Recessus: In Latin, "recessus" means "retreat" or "recess". It is derived from the verb "recedere", which means "to go back" or "to recede".
2. Cochlearis: In Latin, "cochlearis" means "of or pertaining to a snail". It is derived from the Latin noun "cochlea", which means "snail". This term is used to describe the spiral shape of the cochlea in the inner ear, which resembles a snail shell.
Therefore, "recessus cochlearis" literally translates to "the retreat or recess of the cochlea", referring to the anatomical structure within the inner ear.
