The midline groove divides the anterior part of the tongue into the left and right parts. The inferior surface is connected to the floor of the mouth by a fold known as the frenulum
The tongue consists of a tip, dorsal surface, ventral surface, and root. It is made up of four pairs of muscles: 1. Intrinsic (entirely within the tongue): superior longitudinal, inferior longitudinal, vertical, and transverse muscles. Their role is to change the shape of the tongue, having a role in facilitating speech, eating, and swallowing
The tongue is a muscular organ in the mouth of a typical vertebrate.It manipulates food for mastication and swallowing as part of the digestive process, and is the primary organ of taste.The tongue's upper surface (dorsum) is covered by taste buds housed in numerous lingual papillae.It is sensitive and kept moist by saliva and is richly supplied with nerves and blood vessels INFERIOR SURFACE Covered by smooth mucous membrane In the midline, a mucosal fold called Frenulum connects the tongue with the floor of the mouth Lateral to frenulum, deep lingual vein can be seen through the mucosa Lateral to the lingual vein, mucosal fold called as plica fimbriata is present 14 The tongue is covered with moist, pink tissue called mucosa.

The inferior surface of the tongue can also be subdivided into an apex and a body. This surface becomes visible when we lift the tongue to touch the roof of the mouth. A fold known as the frenulum can be seen to connect this inferior surface to the floor of the mouth. A vein, known as deep lingual vein, is also visible on the two sides of the. Inferior surface of tongue The under surface of the oral part of the tongue lacks papillae, but does have a number of linear mucosal folds. A single median fold (the frenulum of tongue) is continuous with the mucosa covering the floor of the oral cavity, and overlies the lower margin of a midline sagittal septum, which internally separates th

The T muscle connects the medial septum to the lateral aspect of the tongue. The V muscle connects the inferior surface to the superior surface The vertical muscles connect the inferior surface to the superior surface; they are believed to flatten the tongue. ( D ) The hyoglossus (HG) muscles originate from the hyoid bone and also insert into the inferior-lateral margins of the tongue, they are believed to cause tongue retraction and depression A healthy tongue is usually pink in appearance, with small, painless nodules. If your tongue is red, yellow, or white, you likely need to address a health issue Tongue cancer is a type of cancer that starts in the cells of the tongue, and can cause lesions or tumors on your tongue. It's a type of head and neck cancer The deep lingual artery is the terminal part of the lingual artery and is found on the inferior surface of the tongue near the lingual frenulum. In addition to the lingual artery, the tonsillar and ascending palatine branches of the facial and ascending pharyngeal arteries also supply tissue in the root of the tongue
The intrinsic muscles of the tongue that we will examine are shown in figure 7.2: The superior longitudinal muscle, with fibers that run anteroposteriorly (from the front to the back) along the superior surface of the tongue, just below the mucous membrane. The inferior longitudinal muscle, with fibers that run along the sides of the tongue, fro The epithelium covering the inferior surface of the tongue is thinner and more from BIOLOGY 2402 at Cedar Valley Colleg The tongue has a dorsum, apex, inferior surface and root. The root (base) is attached to the hyoid bone and mandible while the apex forms the tip of the tongue. The sulcus terminalis, a shallow groove with the circumvallate papillae just anterior to it, divides the tongue into the oral (anterior two-thirds) and pharyngeal (posterior third) parts Veins of the tongue are called vena comitantes. The arrangement of vena comitantes is variable. 2 vena comitantes accompany the lingual artery and 1 vena comitantes accompanies the hypoglossal nerve. The deep lingual vein is the largest and the principal vein of the tongue. It is visible on the inferior surface of the tongue Is the ventral tongue anterior or posterior? From anterior to posterior, the tongue has 3 surfaces: tip, body, and base. The tip is the highly mobile, pointed anterior portion of the tongue. Posterior to the tip lies the body of the tongue, which has dorsal (superior) and ventral (inferior) surfaces (see the image and the video below)
inferior surface of tongue: shapes tongue for speech and mastication: hypoglossal nerve (CN XII) intrinsic muscle with fibers at border of tongue: 10. Describe the oral cavity, its oral vestibule and dental arches (including temporary and permanent dentitions), and the hard and soft palate . What this muscle does is it depresses the tongue. Because it's got its inferior attachment on the hyoid bone, you can see if it contracts, it will bring the tongue downwards. That's the hyoglossus muscle What are the Parts of Tongue? Tongue consists of following parts: Tip/Apex: It is directed forward and is in contact with incisors when the mouth is closed.; Root: Lies in the floor of mouth and is attached to mandible and hyoid bone by muscles. Body: is the part between the tip and root.It has: two surfaces - ventral (inferior) and dorsal (superior) an Anterior surface of the tongue. The tongue is a mass of interlacing skeletal muscle , connective tissue with some mucous and serous glands, and pockets of adipose tissue, covered in oral mucosa. A V-shaped line (shallow groove)- the sulcus terminalis, divides the tongue into an anterior 2/3 and a posterior 1/3 The inferior, or under, surface leads from the tip of the tongue to the floor of the mouth; its mucous membrane is smooth, devoid of papillae, and purple in colour from the many blood vessels present. The root, the remainder of the underside that lies on the mouth's floor, contains bundles of nerves, arteries, and muscles that branch to the.
The mucous membrane of the inferior surface of the tongue is thin, smooth, devoid of papillae, and more loosely attached to the underlying tissue. It exhibits the midline frenulum and some rather rudimentary fimbriated folds that run posterolaterally from the tip of the tongue. The frenulum is a duplication of the mucous membrane and connects. A center line visible on the surface of the tongue is called the medial sulcus. It divides the tongue into equal halves. At the posterior end of the tongue towards the back of the throat, the medial sulcus runs into the terminal sulcus, which is where the posterior tongue anatomically begins an extrinsic muscle of the tongue: inferior oblique: floor of the orbit lateral to the lacrimal groove: sclera on the inferior surface of the eyeball: elevates and abducts the corneal part of the eye; rotates the superior pole of the iris laterally; when the eye is adducted, this muscle elevates the cornea: oculomotor nerve (III), inferior divisio

Depending on the location of the muscle, the tongue can be moved forward and backward and can also be elevated and depressed. There are 5 extrinsic tongue muscles: Genioglossus muscle The genioglossus originates from the inner surface of the mandibl
The inferior surface of the tongue in the midline has the frenulum of the tongue. On either side of the frenulum the deep vein of the tongue can be seen and also the openings of the ducts of the submandibular glands (Figs 7.27, 7.29). Muscles The inferior longitudinal muscle of tongue is a narrow band situated on the under surface of the tongue between the genioglossus and hyoglossus. The tongue is a muscular organ in the mouth of most vertebrates that manipulates food for mastication, and is used in the act of swallowing

The intrinsic muscles are the vertical muscle, the transverse muscle, the superior longitudinal muscle, and the inferior longitudinal muscle. They work together to provide the movements necessary for speech and swallowing. The superior longitudinal muscle runs under the surface of the tongue while the inferior longitudinal muscle lines the sides Laryngeal cavity. The laryngeal central cavity is tubular in shape and lined with mucosa. The superior aspect of the cavity (laryngeal inlet) opens into the pharynx, inferior and posterior to the tongue. The inferior aspect of the cavity is continuous with the lumen of the trachea

Intrinsic Muscles. The intrinsic muscles only attach to other structures in the tongue. There are four paired intrinsic muscles of the tongue and they are named by the direction in which they travel: the superior longitudinal, inferior longitudinal, transverse and vertical muscles of the tongue.These muscles affect the shape and size of the tongue - for example, in tongue rolling - and. The tongue also helps to produce speech by altering or stopping the flow of air through the mouth to produce the sounds of many consonants. The hard and soft palates form the roof of the mouth. On the anterior end of the mouth, the hard palate is formed by the inferior surface of the maxillae and palatine bones Visible on inferior surface of tongue, near the median plane.

The hyoglossal membrane anchors the inferior posterior edge of the tongue to the hyoid bone. The lingual septum inserts into the hyoglossal membrane and extends superiorly along the midline of the tongue (Figs 1 -3). It divides the tongue into halves and provides attachments for the transverse intrinsic muscles (4,5) Surface of eyeball between inferior rectus and lateral rectus: Moves eyes down and away from nose; rotates eyeball from 6 o'clock to 9 o'clock: Eyeballs: Superior (elevates); lateral (abducts) Extrinsic tongue muscles insert into the tongue from outside origins, and the intrinsic tongue muscles insert into the tongue from origins within.
Canker Sore. These painful ulcers can pop up on the soft areas of your mouth, gums, or under the tongue. They can cause your tongue to tingle or burn, especially a day or two before the sores show up The epithelium is thicker at the dorsal surface of the tongue than that in the ventral one. Also, the epithelium of the anterior region of the tongue is thicker than that in the posterior one. The lingual glands (Figs.2,3) are present laterally along the free portion of the tongue. The lingual glands ar Tip, anterior surface of styloid process. Side of tongue. Pulls the tongue upwards and backwards during swallowing. Hypoglossal nerve. Palatoglossus.

Pharyngeal Plexu The Vm extends from the dorsum to the mucosa of the inferior surface of the tongue. The intrinsic muscles have been sometimes investigated using the histological sections of fetuses [ 2 , 3 , 8 , 18 ], and some studies demonstrated the three-dimensional models of the outline of the muscles of the tongue [ 12 , 16 ] Its origin is the internal surface of the mandible near the symphysis and its insertion is along the inferior aspect of the tongue and the body of the hyoid. hyoglossus - This muscle derives its name from its connection to the hyoid bone. This muscle depresses the tongue and draws its sides downward
thickenings of the anterior anläge and posteriorly by the embryonal fissure between the anterior and the posterior anläge of the tongue. While it spread slowly against thelatter, the mass ended sharply at former, with overhanging walls. The same was true of the small mass on the inferior surface of the tongue. It also originated from the cen¬ tral line of the tongue, like the superior one. The inferior limit of the lips in the central region is the mentolabial sulcus. Anatomically, the philtrum and its pillars are a part of the upper lip. The surface of the lip is comprised of four zones: hairy skin, vermilion border, vermilion and oral mucosa. The normal shape of the lips varies with age, and is influenced by ethnicity. Vermilion A combined median swelling on the pharyngeal surface of the combined third and fourth pharyngeal arches. This swelling will give rise to the posterior third of the tongue and the epiglottic apparatus. Thyroglossal duct. The duct that initially runs between the developing thyroid gland and the surface of the tongue, where it opens at the foramen. that separates the body of the tongue from the base of the tongue. At the tip of this sulcus is the foramen cecum, a remnant of the proximal thyroglossal duct. The base of tongue contains the lingual tonsils, the inferior most portion of Waldeyer's ring [7-9]. The body of the tongue derives its characteristic surface appearanc
The terminal branches ascend on the external and superior surface of hypoglossus to provide general somatic afferent innervation to the mucus membrane of the anterior two-thirds of the tongue. Hypoglossal nerve: Lies deep to the submandibular gland and runs superficial to hyoglossus and deep to digastric muscle Basal cell carcinoma (BCC) is the most common skin cancer. Its occurrence in the oral mucosa is extremely rare. We report the clinical course of BCC arising in the inferior surface of the tongue. We performed a super selective intra-arterial chemotherapy combined with radiotherapy for this case. Loc Four were implanted under the lateral dorsal tongue surface, bilaterally at the junction of the palatoglossal arch with the tongue and at the lateral border of the tongue, and halfway between the. Surgical Anatomy. The tongue merges anteriorly and laterally with the floor of mouth (FOM), a horseshoe-shaped area that is confined peripherally by the inner aspect (lingual surface) of the mandible.Posterolaterally the tonsillolingual sulcus separates the tongue from the tonsil fossa. Posteriorly the vallecula separates the base of tongue from the lingual surface of the epiglottis
The depressions, between the surface of the epiglottis adjacent to the tongue and the root of the tongue, on the two sides of the median glossoepiglottic fold, are known as the vallecula. There are some taste buds on the epiglottis, innervated by vagus nerve fibers form the inferior ganglion  The inferior longitudinal muscle depresses the tip and lateral surface of the tongue, thus, shaping the dorsal surface of the tongue into convexity. Taste buds: The taste buds present on the tongue contain taste villi The tongue's embryonic orgin is derived from all pharyngeal arches contributing different components. As the tongue (Latin, lingua; Greek, glossa) develops inside the floor of the oral cavity, it is not readily visible in the external views of the embryonic (Carnegie) stages of development.Tongue muscle cells originate from somites mesoderm, while muscles of mastication derive from the. Since the wound was gaping, bisected the tongue, and had persistent bleeding, we elected to suture it closed. Anesthesia was obtained with bilateral inferior alveolar nerve blocks, and the wound was closed with a two-layer technique with effective hemostasis and a good cosmetic result. In follow up, the patient sent us photos of her repaired.
