Anterior Lingual Glands
Anterior lingual glands (also called apical glands) are deeply placed seromucous glands that are located near the tip of the tongue on each side of the '' frenulum linguae''. They are found on the under surface of the apex of the tongue, and are covered by a bundle of muscular fibers derived from the '' Styloglossus'' and ''Longitudinalis inferior''. They are between in length, and approximately wide, and each opens by three or four ducts on the under surface of the tongue's apex. The anterior lingual glands are sometimes referred by eponymous names such as: * ''Bauhin's glands'': Named after Swiss anatomist Gaspard Bauhin (1560–1624). * ''Blandin's glands'': Named after French surgeon Philippe-Frédéric Blandin (1798-1849). * ''Nuhn's glands'': Named after German anatomist Anton Nuhn (1815–1889). These glands are present in the large apes but not in the small apes like gibbons and represent an evolutionary divergence. References Mondofacto Dictionary{Dead link, date=Sep ...

Seromucous Gland
Exocrine glands are glands that secrete substances on to an epithelial surface by way of a duct. Examples of exocrine glands include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, prostate and mucous. Exocrine glands are one of two types of glands in the human body, the other being endocrine glands, which secrete their products directly into the bloodstream. The liver and pancreas are both exocrine and endocrine glands; they are exocrine glands because they secrete products—bile and pancreatic juice—into the gastrointestinal tract through a series of ducts, and endocrine because they secrete other substances directly into the bloodstream. Exocrine sweat glands are part of the integumentary system; they have eccrine and apocrine types. Classification Structure Exocrine glands contain a glandular portion and a duct portion, the structures of which can be used to classify the gland. * The duct portion may be branched (called compound) or unbranched (called simple) ...

Tongue
The tongue is a muscular organ (anatomy), organ in the mouth of a typical tetrapod. It manipulates food for mastication and swallowing as part of the digestive system, 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. The tongue also serves as a natural means of oral hygiene, cleaning the teeth. A major function of the tongue is the enabling of speech in humans and animal communication, vocalization in other animals. The human tongue is divided into two parts, an oral cavity, oral part at the front and a pharynx, pharyngeal part at the back. The left and right sides are also separated along most of its length by a vertical section of connective tissue, fibrous tissue (the lingual septum) that results in a groove, the median sulcus, on the tongue's surface. There are two groups of muscle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
