MEMBRANA CRICOTHYREOLDEA Meaning and
Definition
-
Membrana cricothyroidea, also known as the cricothyroid membrane, is a vital anatomical structure located in the neck region of the human body. It is a thin, elastic, and fibrous membrane that connects the cricoid cartilage and the thyroid cartilage, two important cartilages of the larynx. The cricothyroid membrane is positioned just above the vocal folds and helps to maintain the structural integrity of the larynx.
Functionally, the membrana cricothyroidea plays a crucial role in voice production. It serves as the point of attachment for the cricothyroid muscle, a key muscle responsible for controlling the tension of the vocal cords. When the cricothyroid muscle contracts, it causes the vocal folds to stretch and lengthen, facilitating the production of higher-pitched sounds in speech. Conversely, relaxation of this muscle results in a lower pitch.
The membrana cricothyroidea also contributes to the protection of the airway during swallowing and breathing. It helps to maintain the open passage of air during respiration and prevents foreign objects from entering the trachea. In emergency situations, the cricothyroid membrane can be punctured to establish an emergency airway, a procedure known as a cricothyrotomy.
In summary, the membrana cricothyroidea is a thin and flexible membrane located in the neck area that connects the cricoid and thyroid cartilages. It has a crucial role in voice production, facilitating sound modulation, and also acts as a protective barrier for the airway.

Conus elasticus, a membrane filling the interval between the cricoid and thyroid cartilages anteriorly; laterally it is attached above to the inferior thyroarytenoid igament (ligamentum vocale).

Etymology of MEMBRANA CRICOTHYREOLDEA
The word "membrana cricothyreoldea" is not a common term, and there is no specific etymology available for it. However, we can break it down to understand its components:
1. Membrana: This is a Latin word meaning "membrane", which refers to a thin sheet or layer of tissue that covers or lines a part of the body.
2. Cricothyreoldea: This term seems to be a combination of two medical terms:
a) Cricothyroid: "Cricothyroid" refers to the cricothyroid muscle, which is located in the neck and helps control the pitch of the voice by adjusting the tension of the vocal cords.
b) Larynx: In medical terminology, "larynx" is commonly referred to as the voice box.
