Lingual Septum
The lingual septum consists of a vertical layer of fibrous tissue, extending throughout the entire length of the median plane of the tongue, though not quite reaching the dorsum. The lingual septum is closely associated with the hyoglossus membrane, allowing the binding of the tongue to the hyoid muscles. 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.

Transverse Plane
A transverse plane is a plane that is rotated 90° from two other planes. Anatomy The transverse plane is an anatomical plane that is perpendicular to the sagittal plane and the dorsal plane. It is also called the axial plane or horizontal plane, especially in human anatomy, but horizontal plane can be misleading with other animals. The plane splits the body into a cranial (head) side and caudal (tail) side, so in humans the plane will be horizontal (dividing the body into superior and inferior sections) but in quadrupeds it will be vertical.

Median Plane
Whether in reference to the anatomy of the human or other members of the Bilateria, the median plane, also called the midsagittal plane and related terms, is used to describe the sagittal plane as it bisects the body vertically through the midline marked by the navel, dividing the body exactly in left and right side. The term parasagittal plane is used to refer to any plane parallel to the sagittal and median plane. It is one of the lines used to define the right upper quadrant of the human abdomen. The midsternal line can be interpreted as a segment of the median plane. File:Sagittal brain MRI.jpg, Median plane magnetic resonance imaging of the head.

Tongue
The tongue is a Muscle, muscular organ (anatomy), organ in the mouth of a typical tetrapod. It manipulates food for chewing 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 cleaning the teeth. A major function of the tongue is to enable 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 glossal muscles. The f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsum (biology)
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Terminolog ...

Hyoglossal Membrane
The hyoglossal membrane is a strong fibrous lamina, which connects the under surface of the root of the tongue to the body of the hyoid bone. It is characterized by a posterior widening of the lingual septum. This membrane receives, in front, some of the fibers of the Genioglossi. Inferior fibers are attached to hyoglossal membrane, and to the upper anterior body of the midline of hyoid bone. References Human head and neck {{Portal bar, Anatomy ...

Hyoid Bone
The hyoid-bone (lingual-bone or tongue-bone) () 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 muscles or ligaments. It is the only bone in the human body that is not connected to any other bones. The hyoid is anchored by muscles from the anterior, posterior and inferior directions, and aids in tongue movement and swallowing. The hyoid bone provides attachment to the muscles of the floor of the mouth and the tongue above, the larynx below, and the epiglottis and pharynx behind. Its name is derived . Structure The hyoid bone is classed as an irregular bone and consists of a central part called the body, and two pairs of horns, the greater and lesser horns.

Fibrocartilage
Fibrocartilage consists of a mixture of white fibrous tissue and cartilaginous tissue in various proportions. It owes its inflexibility and toughness to the former of these constituents, and its elasticity to the latter. It is the only type of cartilage that contains type I collagen in addition to the normal type II. Structure The extracellular matrix of fibrocartilage is mainly made from type I collagen secreted by chondroblasts.

Tongue Piercing
A tongue piercing is a body piercing usually done directly through the center of the tongue. Since its decline in popularity around 2011, it has seen a recent upsurge making it now the second most popular piercing amongst young women aged 18–25 in 2019. It has become quite unpopular amongst men, although in the 1990s and early 2000s, it was more popular for men than women to get and associated with punk culture. Midline tongue piercings, or one hole through the center of the tongue is the most common way to have the tongue pierced. History and culture The term "tongue ring" is often used to refer to tongue piercing, but this is not accurate as rings are rarely worn in tongue piercings. There is a history of ritual tongue piercing in Aztec and Maya cultures. Priests would pierce their tongues and either draw blood from them or pass rough cords through to inflict pain. However, there is no evidence that the Aztecs practiced long-term or permanent tongue piercing, despite the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tongue Splitting
Tongue bifurcation, splitting or forking, is a type of body modification in which the tongue is cut centrally from its tip to as far back as the underside base, forking the end. Bifid tongue in humans may also be an unintended complication of tongue piercingsFleming, P., Flood, T. Bifid tongue — a complication of tongue piercing.

Practice Deliberate tongue splitting is a cosmetic body modification procedure that results in a ‘lizard-like’ bifid tongue. Tongue bifurcation has also been reported as an unintended complication of tongue piercing. Process Tongue bifurcation may be done surgically using a scalpel, or cauterised with a laser.

Mouth Cavity
A mouth also referred to as the oral is the body orifice through which many animals ingest food and vocalize. The body cavity immediately behind the mouth opening, known as the oral cavity (or in Latin), is also the first part of the alimentary canal, which leads to the pharynx and the gullet. In tetrapod vertebrates, the mouth is bounded on the outside by the lips and cheeks — thus the oral cavity is also known as the buccal cavity (from Latin ', meaning "cheek") — and contains the tongue on the inside. Except for some groups like birds and lissamphibians, vertebrates usually have teeth in their mouths, although some fish species have pharyngeal teeth instead of oral teeth. Most bilaterian phyla, including arthropods, molluscs and chordates, have a two-opening gut tube with a mouth at one end and an anus at the other. Which end forms first in ontogeny is a criterion used to classify bilaterian animals into protostomes and deuterostomes. Development In the first multice ...
