The larynx (/ ˈlærɪŋks /), commonly called the voice box, is an organ in the top of the neck involved in breathing, producing sound and protecting the trachea against food aspiration. The opening of larynx into pharynx known as the laryngeal inlet is about 4–5 centimeters in diameter. [1]
The aryepiglottic muscle or aryepiglotticus muscle, often considered the aryepiglottic part of oblique arytenoid muscle, is an intrinsic muscle of the larynx. [1] It is a direct continuation of a portion of the fibers of the oblique arytenoid muscle, sharing its innervation and blood supply, after these select fibers travel laterally around the arytenoid apex to the aryepiglottic fold.
Vocal cord paresis, also known as recurrent laryngeal nerve paralysis or vocal fold paralysis, is an injury to one or both recurrent laryngeal nerves (RLNs), which control all intrinsic muscles of the larynx except for the cricothyroid muscle. The RLN is important for speaking, breathing and swallowing. [1][2]
The recurrent laryngeal nerve (RLN) is a branch of the vagus nerve (cranial nerve X) that supplies all the intrinsic muscles of the larynx, with the exception of the cricothyroid muscles. There are two recurrent laryngeal nerves, right and left. The right and left nerves are not symmetrical, with the left nerve looping under the aortic arch ...
Sagittal section of the larynx and upper part of the trachea. (Arytenoideus visible at center right.) The arytenoid muscle / ærɪˈtiːnɔɪd / or interarytenoid muscle is a composite intrinsic muscle of the larynx, consisting of a transverse part and an oblique part - the two parts may be considered as separate muscles: an unpaired transverse ...
Anatomical terms of muscle. [edit on Wikidata] The posterior cricoarytenoid muscle is a (bilaterally paired) intrinsic muscle of the larynx. It arises from the cricoid cartilage; it inserts onto the arytenoid cartilage of the same side. It is innervated by the recurrent laryngeal nerve. Each acts to open the vocal folds by pulling the vocal ...
Vocal folds (speaking) In humans, the vocal cords, also known as vocal folds, are folds of throat tissues that are key in creating sounds through vocalization. The length of the vocal cords affects the pitch of voice, similar to a violin string. Open when breathing and vibrating for speech or singing, the folds are controlled via the recurrent ...
Right lamina of thyroid cartilage removed. The lateral cricoarytenoid (also anterior cricoarytenoid) is an intrinsic muscle of the larynx. It attaches at the cricoid cartilage anteriorly, and at the arytenoid cartilage of the same side posteriorly. It is innervated by the recurrent laryngeal nerve. It acts to close the rima glottidis, thus ...
