RECESSUS MEMBRANAE TYMPANI POSTERIOR Meaning and
Definition
-
Recessus Membranae Tympani Posterior is a term used in anatomy and specifically in the study of the human ear. It refers to a small cavity or recess found in the middle ear, located behind the eardrum or the tympanic membrane.
The recessus membranae tympani posterior is a space that lies within the temporal bone of the skull. It is situated in close proximity to the middle ear cavity, which contains important auditory structures like the ossicles - the small bones involved in transmitting sound waves.
This recess is located specifically behind the eardrum, towards the posterior or back side. It is connected to the mastoid air cells, which are air-filled spaces in the mastoid part of the temporal bone. The mastoid air cells are responsible for regulating the pressure in the middle ear and draining any excess fluid or mucus.
The recessus membranae tympani posterior can vary in size and shape between individuals. Its presence is important in maintaining normal middle ear function and facilitating the exchange of air between the middle ear and mastoid air cells. Any abnormalities or disorders affecting this recess may lead to disturbances in ear pressure regulation or the potential for fluid accumulation, which can affect hearing and lead to related problems.
In summary, the recessus membranae tympani posterior is a small cavity located behind the eardrum in the middle ear. It plays a role in maintaining normal ear function and interacts with the mastoid air cells for pressure regulation and drainage.
