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.
The anterior oral part is the visible part situated at the front and makes up roughly two-thirds the length of the tongue. The posterior pharyngeal part is the part closest to the throat, roughly one-third of its length. These parts differ in terms of their embryological development and nerve supply.
These are present mostly at the dorsal surface of the tongue, as well as at the sides. Innervated by facial nerve. Foliate papillae - these are ridges and grooves towards the posterior part of the tongue found at the lateral borders. Innervated by facial nerve (anterior papillae) and glossopharyngeal nerve (posterior papillae).
Lingual tonsils are located on posterior aspect of tongue which is supplied through: [1] Lingual artery, branch of external carotid artery; Tonsillar artery; Ascending and descending palatine arteries; Ascending pharyngeal branch of external carotid artery
Older set of terminology shown in Parts of the Human Body: Posterior and Anterior View from the 1933 edition of Sir Henry Morris' Human Anatomy. Many of these terms are medical latin terms that have fallen into disuse. Front: Frons - forehead; Facies - face; Pectus - breast; Latus - flank; Coxa - hip; Genu - knee; Pes - foot; Back: Vertex ...
Ankyloglossia, also known as tongue-tie, is a congenital anomaly characterised by an abnormally short lingual frenulum; when severe, the tip of the tongue cannot be protruded beyond the lower incisor teeth. [6] There are two generalized classifications of ankyloglossia, anterior and posterior tongue-ties.
The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas). The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into:
The lingual septum is closely associated with the hyoglossus membrane, allowing the binding of the tongue to the hyoid muscles. [1] Visualization through implementing a vertical groove along the tongue called the median sulcus. It is thicker behind than in front, and occasionally contains a small fibrocartilage, about 6 mm. in length.
