Sometimes fimbriated folds’ free edges have small minor bumps, but sometimes they appear with more pronounced processes. Folds lie next to noticeable lingual veins. Lateral on both sides of the lingual frenulum is the slight fimbriated folds or plicas made from the mucosa. On sublingual plicas along the sides and towards the caruncle part opens the sublingual salivary gland’s minor ducts. From its sides laterally goes sublingual folds or plicas overlying the sublingual glands. It is the part where opens the sublingual salivary gland central duct and submandibular salivary gland duct. The lingual frenulum ends with the minor swelling- sublingual caruncle. In the midline of the ventral surface, mucosa forms a lingual frenulum connecting the tongue with the oral cavity floor. It is more pronounced at the tip and the anterior part of the tongue’s body areas. Ventral surfaceĬompared to the dorsal surface, the ventral surface is relatively smooth. The superior surface is also known as the dorsal, while the inferior is the ventral surface. The tongue has two surfaces- the superior and the inferior. The tongue has two lateral edges or sides located between both surfaces. In its place, it fixes several extrinsic muscles connecting the root with the hyoid bone and mandible. It is the broadest and the least mobile area of the tongue and, in this part, locate lymphoid tissue and tonsil. It is also known as the postsulcal or pharyngeal part. It starts with the terminal sulcus and ends with the epiglottis. The posterior part or posterior one-third is the root. It is also known as the oral or pre-sulcal part. The tip, together with the body, forms the anterior part. It continues from the tip’s end to the terminal sulcus located in the tongue’s dorsal surface, approximately two-thirds from the apex. The apex is the most mobile and narrowest part, located most forward. The tongue consists of three parts- the apex, also known as the tip, body, and root. The tongue’s base and the lingual tonsil demarcate the isthmus from the bottom. It is known as the oropharyngeal isthmus or opening. The tongue participates in the oral cavity’s posterior opening formation. Posterior is the epiglottis and oropharyngeal isthmus. Superior from the tongue is the soft and hard palate, while inferior is the oral cavity’s floor and sublingual salivary glands. Posterior lateral sides meet the palatoglossal and palatopharyngeal arches and palatine tonsils between them. The tip of the tongue faces the teeth and gingiva, as well as the tongue’s anterior lateral sides. The tongue attaches by muscles to the hyoid bone, the styloid process of temporal bone, mandible, palate, and pharynx. Men’s average tongue length is around 8.5 cm (3.35 inches), while for women it is 8 centimeters (3.15 inches). The tongue has three parts, two surfaces and two edges. The tongue not only helps in food chewing and swallowing, but it also provides tactile, taste, and speech formation functions. It helps to support the floor part of the cavity. glossa) is a pink mobile muscular organ of the digestive system covered by mucosa and located in the oral cavity proper extending to the oropharynx. It doesn't pose a threat to your health, cause long-term complications or increase your risk of major health problems.The tongue (Latin: lingua s. People with geographic tongue often have another disorder called fissured tongue, which has the appearance of deep grooves (fissures) on the surface of the tongue. Some people with geographic tongue have a family history of the disorder, so inherited genetic factors may increase risk.

Factors that are likely associated with an increased risk include: Studies of factors that may be associated with an increased risk of geographic tongue have produced mixed results. But more research is needed to better understand possible connections.
