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.
Larynx. 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]
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 ...
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 ...
Upper respiratory system, with soft palate labeled near center. The soft palate (also known as the velum, palatal velum, or muscular palate) is, in mammals, the soft tissue constituting the back of the roof of the mouth. The soft palate is part of the palate of the mouth; the other part is the hard palate. The soft palate is distinguished from ...
The muscles of the larynx adjust the length and tension of the vocal folds to 'fine-tune' pitch and tone. The articulators (the parts of the vocal tract above the larynx consisting of tongue , palate , cheek , lips , etc.) articulate and filter the sound emanating from the larynx and to some degree can interact with the laryngeal airflow to ...
The production of speech is a highly complex motor task that involves approximately 100 orofacial, laryngeal, pharyngeal, and respiratory muscles. [2] [3] Precise and expeditious timing of these muscles is essential for the production of temporally complex speech sounds, which are characterized by transitions as short as 10 ms between frequency bands [4] and an average speaking rate of ...
Vocal process. In the human larynx, the vocal process is the anterior angle of the base of the arytenoid cartilage, as it projects horizontally forward and gives attachment to the vocal ligament. The arytenoids are paired cartilages with a medial and a lateral process each. The medial process is called the vocal process because it is the ...
