MASTOID CELL Meaning and
Definition
-
A mastoid cell refers to a small, air-filled cavity located within the mastoid process, which is the bony prominencce situated behind the ear. Mastoid cells are part of the mastoid air cell system, a complex network of interconnected cells that are lined with mucous membranes. These cells are an extension of the middle ear cavity and serve several important functions related to hearing and the overall health of the ear.
The mastoid cell plays a crucial role in equalizing air pressure within the middle ear. It helps to regulate the transmission of sound vibrations from the outer to the inner ear and assists in maintaining the equilibrium required for optimal hearing. Additionally, mastoid cells are involved in the secretion and drainage of fluids produced within the ear, contributing to the overall health and cleanliness of the ear canal.
The size and shape of mastoid cells can vary between individuals, and they can occasionally become larger or more numerous due to various factors such as infections or certain congenital conditions. Mastoiditis, an infection of the mastoid air cell system, can occur when the mastoid cells become inflamed and filled with pus. This condition often causes pain, tenderness, and swelling behind the ear. If left untreated, mastoiditis can lead to serious complications, such as the spread of infection to nearby structures, including the brain.
Overall, mastoid cells are an integral component of the middle ear and are vital for maintaining proper hearing and ear health.

Etymology of MASTOID CELL
The word "mastoid" originated from the Greek words "mastós" meaning "breast" and "eídos" meaning "resemblance" or "form". The term was originally used to describe the breast-like shape of the mastoid process, a bony prominence behind the ear.
The word "cell" has Latin origins and it derived from the word "cella" meaning "small, enclosed space". In biology and anatomy, the term "cell" refers to a tiny compartment or chamber.
So, when combined, "mastoid cell" refers to small, enclosed spaces or compartments within the mastoid process. These spaces are often filled with air and connected to the middle ear cavity.
