The thin strip of tissue that runs vertically from the floor of the mouth to the undersurface of the tongue is called the lingual frenulum. It tends to limit the movement of the tongue, and in some people, it is so short that it actually interferes with speaking. A hump of tissue near the base of the tongue houses a series of saliva gland ducts.
The free edge of the fimbriated fold occasionally exhibits a series of fringe-like processes. (Fimbria is Latin for fringe). Some people have small (<1 cm) horn-like triangular flaps of "skin" under their tongue. They are on each side of the frenulum (the piece of tissue connecting the bottom of the tongue to the inside of the mouth) under the ...
Tongue rolling is the ability to roll the lateral edges of the tongue upwards into a tube. The tongue's intrinsic muscles allow some people to form their tongues into specific shapes. Rolling the tongue into a tube shape is often described as a dominant trait with simple Mendelian inheritance , and it is commonly referenced in introductory and ...
The human tongue is divided into two parts, an oral part at the front and a pharyngeal part at the back. The left and right sides are also separated along most of its length by a vertical section of fibrous tissue (the lingual septum) that results in a groove, the median sulcus, on the tongue's surface. There are two groups of glossal muscles.
Fissured tongue is a benign condition characterized by deep grooves in the dorsum of the tongue. Although these grooves may look unsettling, the condition is usually painless. Although these grooves may look unsettling, the condition is usually painless.
The lingual septum is closely associated with the hyoglossus membrane, allowing the binding of the tongue to the hyoid muscles. [1] Visualization through implementing a vertical groove along the tongue called the median sulcus. It is thicker behind than in front, and occasionally contains a small fibrocartilage, about 6 mm. in length.
The lingual nerve supplies general somatic afferent (i.e. general sensory) innervation to the mucous membrane of the anterior two-thirds of the tongue (i.e. body of tongue) (whereas the posterior one-third (i.e. root of tongue) is innervated via the glossopharyngeal nerve (CN IX) [citation needed]), the floor of the oral cavity, and the mandibular/inferior lingual gingiva.
Crenated tongue is usually asymptomatic and harmless. [3] It is not a disease as such, but usually results from habits where the tongue is pressed against the lingual surfaces (the side facing the tongue) of the dental arches, or from any cause of macroglossia (enlarged tongue), [3] which in itself has many causes such as Down syndrome.
