ARYTENOID GLANDS Meaning and
Definition
-
Arytenoid glands refer to a pair of small mucous-secreting glands located within the posterior aspect of the larynx. These glands are specifically found within the arytenoid cartilages, which are two small, pyramid-shaped cartilages situated at the back of the vocal cords. The arytenoid glands are responsible for producing and secreting mucus lubricant, which aids in the smooth movement of the vocal cords during speech and swallowing.
The arytenoid glands play a crucial role in maintaining optimal vocal cord function and protecting the delicate lining of the larynx. The mucus they secrete helps to keep the vocal cords moist and prevents them from drying out. This is particularly important as dry vocal cords can lead to voice hoarseness and strain. Additionally, the mucus produced by these glands acts as a protective barrier against irritants, bacteria, and allergens, reducing the risk of infection or inflammation of the larynx.
In certain medical conditions or situations such as prolonged voice use, dehydration, or respiratory infections, the arytenoid glands may become overactive or disrupted, resulting in an excessive production of mucus or a change in its consistency. This can contribute to voice symptoms such as hoarseness, throat clearing, or coughing. The evaluation and treatment of arytenoid gland disorders are typically carried out by an otolaryngologist (ear, nose, and throat specialist) to ensure effective management and vocal cord health.
Etymology of ARYTENOID GLANDS
The etymology of the term "arytenoid glands" can be broken down as follows:
1. Arytenoid: This word derives from the Greek term "arytenoeides", meaning "shaped like a ladle". It is a combination of "arytenes", which means "pitchfork", and "eidos", meaning "shape" or "form". The arytenoid cartilages in the larynx are named due to their resemblance to a pitchfork or ladle in shape.
2. Glands: This term comes from the Latin word "glandula", which refers to a small organ in the body that secretes substances. It originated from the Latin verb "glans", meaning "acorn", as glands were described to resemble the shape of an acorn.
