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)

Tongue: Anatomy, muscles, neurovasculature and histology

  1. The Tip or Apex: The tip or apex of the tongue accounts for one-third of the anterior surface of the organ. It is highly movable and rests against the incisor teeth in the mouth cavity.. Conventionally, the taste buds for sweet are only present on this part.. The tip also plays its role in the production of labiodental and alveolar sounds
  2. The deep lingual artery and vein and the lingual nerve are situated on the inferior surface of the tongue, so sensory paralysis and bleeding may occur if they are injured. In particular, care should be taken not to injure the deep lingual vein because of its position directly under the mucosa ( Fig. 20.11 )
  3. It is responsible for narrowing and extending the tongue as well as arching the lateral edges of the tongue in an upward direction. Vertical: The task of the vertical muscle of the tongue is to flatten, widen, and lower the tongue. It originates from the lingual aponeurosis and inserts at the lower surface of the tongue
  4. The inferior surface of the tongue: Attached to the sublingual fossa by the Lingual Frenulum. If the lingual Frenulum is too short, it will limit the mobility of the tongue, and thus limit speech (may require surgical detachment) Mucous membrane: On the inferior surface of the tongue is very thin Can see the lingual vein clearly through i

Describe the oral cavity, its oral vestibule and dental arches (including temporary and permanent dentitions), and the hard and soft palate This muscle originates on the greater horn of the hyoid bone and then it inserts onto the lateral surface of the tongue. 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.

Tongue: Anatomy, Function, and Treatmen

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

Tongue: Useful Notes on Tongue (2947 Words

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.
