The tongue is a muscular organ in the mouth of a typical tetrapod. It manipulates food for chewing 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 ...
The hyoid bone (lingual bone or tongue-bone) (/ ˈhaɪɔɪd / [2][3]) is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. At rest, it lies between the base of the mandible and the third cervical vertebra. Unlike other bones, the hyoid is only distantly articulated to other bones by ...
Human mouth. In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. [2] The oral mucosa is the mucous membrane epithelium lining the inside of the mouth. In addition to its primary role as the beginning of the digestive system, the mouth also plays a significant role in communication.
Sagittal section of nose mouth, pharynx, and larynx. (Frenulum linguae is the topmost label at right.) The frenulum (or frenum) of the tongue, tongue web, lingual frenulum, frenulum linguae, or fraenulum[1] is a small fold of mucous membrane extending from the floor of the mouth to the midline of the underside of the human tongue.
In humans, the mandible is the largest and lowest bone in the facial skeleton. [2] It is the only movable bone of the skull (discounting the vibrating ossicles of the middle ear). [3] It is connected to the skull's temporal bones by the temporomandibular joints.
The tongue is a specialized skeletal muscle that is specially adapted for the activities of speech, chewing, developing gustatory sense (taste) and swallowing. The tongue contains two sets of muscles, the intrinsic- involved with shape of tongue, and the extrinsic- involved with tongue movement. It is attached to the hyoid bone.
Frenulum. Anatomy of the human mouth, including the frenulum of the tongue. A frenulum / ˈfrɛnjʊləm / or frenum / ˈfriːnəm / (pl.: frenula or frena, from the Latin frēnulum, "little bridle", the diminutive of frēnum[1]) is a small fold of tissue that secures the motion of a mobile organ in the body.
The genioglossus is one of the paired extrinsic muscles of the tongue. It is a fan-shaped muscle that comprises the bulk of the body of the tongue. It arises from the mental spine of the mandible; it inserts onto the hyoid bone, and the bottom of the tongue. It is innervated by the hypoglossal nerve (cranial nerve XII).
