The vertical muscle of the tongue is an intrinsic muscle of the tongue. Its fibers extend from the upper to the under surface of the tongue. It is innervated by the hypoglossal nerve (cranial nerve XII). Its contraction flattens, widens and elongates the tongue. [citation needed]
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.
The transverse muscle of tongue (transversus linguae) is an intrinsic muscle of the tongue. [1] It consists of fibers which arise from the median fibrous septum. It passes laterally to insert into the submucous fibrous tissue at the sides of the tongue. [citation needed] It is innervated by the hypoglossal nerve (cranial nerve XII). Its ...
The tongue is a specialized skeletal muscle that is specially adapted for the activities of speech, chewing, developing gustatory sense (taste) and swallowing. The tongue contains two sets of muscles, the intrinsic- involved with shape of tongue, and the extrinsic- involved with tongue movement. It is attached to the hyoid bone.
The tongue is one of the primary articulators in the production of speech, and this is facilitated by both the extrinsic muscles that move the tongue and the intrinsic muscles that change its shape. Specifically, different vowels are articulated by changing the tongue's height and retraction to alter the resonant properties of the vocal tract .
The hypoglossal nerve provides motor control of the extrinsic muscles of the tongue: genioglossus, hyoglossus, styloglossus, and the intrinsic muscles of the tongue. [2] These represent all muscles of the tongue except the palatoglossus muscle, which is innervated by the vagus nerve. [2] The hypoglossal nerve is of a general somatic efferent ...
The extrinsic muscles act on the region and pass between the larynx and parts around it but have their origin elsewhere; the intrinsic muscles are confined entirely within the larynx and have their origin and insertion there. [5] The intrinsic muscles are divided into respiratory and the phonatory muscles (the muscles of phonation).
The inferior longitudinal muscle of the tongue is an intrinsic muscle of the tongue. [1] It is thin and oval in cross-section. It is situated between the paramedian septum, and the lateral septum. [2] It extends from the root to the apex of the tongue. Posteriorly, some of its fibers attach onto the body of the hyoid bone.
