It is an accessory digestive organ made up of skeletal muscles covered with a mucous membrane. Situated in the oral cavity, the tongue, along with its associated muscles, forms the floor of the mouth. Divided into symmetrical lateral halves by a median septum, the tongue is attached to the hyoid bone, styloid process of the temporal bone, and mandible, giving it stability and mobility.<\/p>\n<p><img loading=\"lazy\" class=\"alignnone size-full wp-image-667782\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2023\/08\/Tongue.png\" alt=\"Tongue\" width=\"528\" height=\"417\" srcset=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2023\/08\/Tongue.png 528w, https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2023\/08\/Tongue-300x237.png 300w\" sizes=\"(max-width: 528px) 100vw, 528px\" \/><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Musculature_of_tongue\"><\/span>Musculature of tongue<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The tongue&#8217;s movement and manipulation are made possible by its extrinsic and intrinsic muscles.<\/p>\n<ol>\n<li><strong>The extrinsic muscles,<\/strong> originating outside the tongue and inserted into connective tissues within it, include the hyoglossus, genioglossus, and styloglossus muscles. These muscles allow the tongue to move side to side and in and out, assisting in chewing, shaping food into a rounded mass, and pushing it to the back of the mouth for swallowing. Additionally, they form the floor of the mouth and maintain the tongue&#8217;s position.<\/li>\n<li><strong>The intrinsic muscles of the tongue<\/strong> originate and insert into connective tissues within the tongue itself. These muscles contribute to altering the tongue&#8217;s shape and size, essential for speech and swallowing. Some intrinsic muscles include the longitudinalis superior, longitudinalis inferior, transversus linguae, and verticalis linguae muscles, each playing a specific role in tongue movement.<\/li>\n<\/ol>\n<h3><span class=\"ez-toc-section\" id=\"Lingual_frenulum\"><\/span>Lingual frenulum<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>It is a fold of mucous membrane found on the undersurface of the tongue, that connects the tongue to the floor of the mouth. It serves to limit the tongue&#8217;s posterior movement. When a person has an abnormally short or rigid lingual frenulum, a condition known as ankyloglossia or being &#8220;tongue-tied,&#8221; speech can be impaired. However, this condition can be surgically corrected.<\/p>\n<p><a href=\"https:\/\/infinitylearn.com\/surge\/articles\/biology-articles\"><button class=\"btn btn-dark mx-2 my-2 px-4\" style=\"border-radius: 80px;\" type=\"button\">Biology Articles<\/button><\/a> <a href=\"https:\/\/infinitylearn.com\/surge\/articles\/animal-husbandry\/\"><button class=\"btn btn-dark mx-2 my-2 px-4\" style=\"border-radius: 80px;\" type=\"button\">Animanl Husbandry<\/button><\/a> <a href=\"https:\/\/infinitylearn.com\/surge\/articles\/heart\/\"><button class=\"btn btn-dark mx-2 my-2 px-4\" style=\"border-radius: 80px;\" type=\"button\">Heart<\/button><\/a> <a href=\"https:\/\/infinitylearn.com\/surge\/articles\/blood\/\"><button class=\"btn btn-dark mx-2 my-2 px-4\" style=\"border-radius: 80px;\" type=\"button\">Blood<\/button><\/a><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Lingual_papillae\"><\/span>Lingual papillae<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The upper surface and sides of the tongue are covered with papillae, nipple-shaped projections formed by the lamina propria covered with stratified squamous epithelium.<\/p>\n<ol>\n<li><strong>Filiform papillae<\/strong> are the most numerous and cover most of the tongue&#8217;s dorsal surface. They are slender, thread-like papillae and do not contain taste buds. Instead, their primary function is to increase friction between the tongue and food, aiding in the manipulation of food during chewing and swallowing.<\/li>\n<li><strong>Fungiform papillae<\/strong> are mushroom-shaped papillae that are scattered among the filiform papillae on the tongue&#8217;s surface. These papillae contain taste buds and are involved in taste perception. They are particularly sensitive to sweet, sour, and salty tastes.<\/li>\n<li><strong>Circumvallate papillae<\/strong> are large, circular papillae located at the back of the tongue in a V-shaped row. They also contain taste buds and are responsible for detecting different tastes. There are typically only a few circumvallate papillae on the tongue, and they are involved in taste perception and the initiation of the swallowing reflex.<\/li>\n<li><strong>Foliate papillae<\/strong> are leaf-shaped papillae found on the sides of the tongue, especially in the posterior region. They contain taste buds and play a role in taste perception, particularly for bitter tastes. While they are more prominent in infants and young children, foliate papillae tend to decrease in size and become less visible with age.<\/li>\n<\/ol>\n<h3><span class=\"ez-toc-section\" id=\"Lingual_glands\"><\/span>Lingual glands<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Lingual glands in the lamina propria of the tongue secrete mucus and a watery serous fluid containing the enzyme lingual lipase. This enzyme plays a vital role in the initial digestion of dietary triglycerides, converting them into simpler fatty acids and diglycerides.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Foramen_Cecum\"><\/span>Foramen Cecum<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The foramen cecum is a small depression or pit-like structure located at the back of the tongue, near the base. It is the region that marks the origin of the thyroid gland during during early fetal development. The foramen cecum is situated at the junction of the anterior two-thirds and the posterior one-third of the tongue.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Lingual_tonsils\"><\/span>Lingual tonsils<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The lingual tonsil is a part of the lymphatic system located at the base of the tongue. It consists of clusters of lymphoid tissue covered with mucous membranes and plays a vital role in the body&#8217;s immune response. Like other tonsils (palatine, tubal, and pharyngeal), it helps protect against infections by detecting and trapping harmful pathogens that may enter through the mouth. The lingual tonsil can become inflamed or enlarged due to infections, causing discomfort and difficulty swallowing. Medical evaluation and treatment may be necessary in such cases.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Functions_of_the_Tongue\"><\/span>Functions of the Tongue<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li><strong>Taste perception<\/strong><\/li>\n<\/ul>\n<p>The tongue is renowned for its role in providing our sense of taste, enabling humans to discern five fundamental taste sensations: sweet, salty, bitter, sour, and umami. This gustatory sense aids the brain in determining the nutritional value of what is being consumed. Bitter or sour tastes can signal spoiled food, while salty or sweet tastes indicate high caloric content, aiding in food evaluation.<\/p>\n<ul>\n<li><strong>Mastication<\/strong><\/li>\n<\/ul>\n<p>Scientifically referred to as mastication, chewing involves the breakdown of food with the assistance of saliva. The tongue plays a pivotal role in this process by ensuring proper mixing of food particles and saliva. Thorough chewing enhances nutrient accessibility, facilitates swallowing, and promotes smoother digestion. Functionally, the tongue aids in maneuvering food within the oral cavity, combining it with saliva, and forming it into a cohesive bolus ready for swallowing.<\/p>\n<ul>\n<li><strong>Deglutition<\/strong><\/li>\n<\/ul>\n<p>After thorough mastication and blending with saliva, food transforms into a compact mass termed a bolus. The tongue serves as a propulsive force, guiding the bolus from the oral cavity to the esophagus. Subsequently, the bolus travels through the esophagus to reach the stomach for digestion.<\/p>\n<ul>\n<li><strong>Articulation and phonation<\/strong><\/li>\n<\/ul>\n<p>Analogous to the teeth, the tongue assumes a pivotal role in articulation and sound formation during speech. While speaking, air from the lungs vibrates the vocal cords, and the resulting vibrations travel through the mouth. The tongue, in conjunction with the teeth and lips, shapes the airflow, generating diverse sounds. For instance, critical sounds such as &#8220;T,&#8221; &#8220;D,&#8221; and &#8220;L&#8221; heavily rely on the tongue&#8217;s positioning and movement during speech.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Summary\"><\/span>Summary<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The tongue, a vital organ in the oral cavity, serves essential functions in both the digestive and communication processes. Comprising skeletal muscles covered by mucous membranes, it plays a crucial role in taste perception, detecting sweet, salty, bitter, sour, and umami flavors, aiding the brain in assessing nutritional value and potential hazards of ingested substances. Additionally, the tongue is pivotal in mastication, effectively breaking down food with the assistance of saliva, enhancing nutrient accessibility, and facilitating swallowing.<\/p>\n<p>It propels the compacted bolus to the esophagus for digestion. Furthermore, the tongue is integral to speech formation, collaborating with the teeth and lips to modulate airflow and generate distinct sounds. Its anatomy, including extrinsic and intrinsic muscles, lingual frenulum, lingual papillae, and lingual glands, collectively enables these functions. The lingual tonsil, part of the lymphatic system, contributes to the immune response. Its significance lies not only in its multifaceted roles but also in its potential to reflect overall health and well-being.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"FAQs_on_Tongue\"><\/span>FAQs on Tongue<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\t\t<section class=\"sc_fs_faq sc_card \">\n\t\t\t<div>\n\t\t\t\t<h3><span class=\"ez-toc-section\" id=\"What_are_the_primary_taste_sensations_that_the_tongue_can_detect\"><\/span>What are the primary taste sensations that the tongue can detect? <span class=\"ez-toc-section-end\"><\/span><\/h3>\t\t\t\t<div>\n\t\t\t\t\t\t\t\t\t\t<p>\n\t\t\t\t\t\tThe tongue can sense five fundamental taste sensations: sweet, salty, bitter, sour, and umami.
