== Interarytenoid Fold ==


==Etymology==
[[File:Gray1204.png|thumb|right|Diagram of the larynx showing the interarytenoid fold.]]
The term "interarytenoid" is derived from the Latin words "inter", meaning between, and "arytenoid", referring to the arytenoid cartilages. The "fold" refers to the shape and structure of this part of the larynx.


==Anatomy==
The '''interarytenoid fold''' is a structure located in the [[larynx]], which is part of the human [[respiratory system]]. It plays a crucial role in the function of the vocal cords and the production of sound.
The interarytenoid fold is a mucous membrane that extends between the two arytenoid cartilages in the larynx. It is located posteriorly and superiorly to the [[vocal cords]], and is also known as the aryepiglottic fold. The interarytenoid fold contains the [[interarytenoid muscle]], which is responsible for adducting the vocal cords during phonation.


==Function==
== Anatomy ==
The primary function of the interarytenoid fold is to assist in the closure of the [[glottis]] during swallowing, preventing food and liquid from entering the [[trachea]]. It also plays a role in phonation by helping to control the tension of the vocal cords.


==Clinical significance==
The interarytenoid fold is a band of tissue that connects the two [[arytenoid cartilages]] at the posterior aspect of the larynx. It is composed of [[muscle]] and [[connective tissue]], and it is covered by a layer of [[mucous membrane]].
Abnormalities or damage to the interarytenoid fold can lead to various voice disorders, such as [[hoarseness]], [[dysphonia]], and [[aphonia]]. It can also result in [[aspiration]], where food or liquid enters the trachea instead of the [[esophagus]], leading to potential respiratory problems.


==Related terms==
=== Location ===
 
The interarytenoid fold is situated at the back of the larynx, between the two arytenoid cartilages. It is part of the [[glottis]], which is the space between the vocal cords.
 
=== Structure ===
 
The fold contains the [[interarytenoid muscle]], which is responsible for adducting the vocal cords, bringing them together during phonation. This muscle is innervated by the [[recurrent laryngeal nerve]], a branch of the [[vagus nerve]].
 
== Function ==
 
The primary function of the interarytenoid fold is to assist in the closure of the vocal cords during speech and swallowing. By bringing the arytenoid cartilages closer together, it helps to close the glottis, preventing food and liquid from entering the [[trachea]] and facilitating the production of sound.
 
== Clinical Significance ==
 
Dysfunction of the interarytenoid fold can lead to voice disorders, such as [[dysphonia]], or swallowing difficulties, known as [[dysphagia]]. Conditions such as [[vocal cord paralysis]] or [[laryngitis]] can affect the function of the interarytenoid fold.

Interarytenoid Fold[edit]

Diagram of the larynx showing the interarytenoid fold.

The interarytenoid fold is a structure located in the larynx, which is part of the human respiratory system. It plays a crucial role in the function of the vocal cords and the production of sound.

Anatomy[edit]

The interarytenoid fold is a band of tissue that connects the two arytenoid cartilages at the posterior aspect of the larynx. It is composed of muscle and connective tissue, and it is covered by a layer of mucous membrane.

Location[edit]

The interarytenoid fold is situated at the back of the larynx, between the two arytenoid cartilages. It is part of the glottis, which is the space between the vocal cords.

Structure[edit]

The fold contains the interarytenoid muscle, which is responsible for adducting the vocal cords, bringing them together during phonation. This muscle is innervated by the recurrent laryngeal nerve, a branch of the vagus nerve.

Function[edit]

The primary function of the interarytenoid fold is to assist in the closure of the vocal cords during speech and swallowing. By bringing the arytenoid cartilages closer together, it helps to close the glottis, preventing food and liquid from entering the trachea and facilitating the production of sound.

Clinical Significance[edit]

Dysfunction of the interarytenoid fold can lead to voice disorders, such as dysphonia, or swallowing difficulties, known as dysphagia. Conditions such as vocal cord paralysis or laryngitis can affect the function of the interarytenoid fold.
