Inferior Tibiofibular Articulation
The distal tibiofibular joint (tibiofibular syndesmosis) is formed by the rough, convex surface of the medial side of the distal end of the fibula, and a rough concave surface on the lateral side of the tibia. Below, to the extent of about 4 mm, these surfaces are smooth and covered with cartilage, which is continuous with that of the ankle joint. The ligaments are: * Anterior ligament of the lateral malleolus * Posterior ligament of the lateral malleolus * Interosseous membrane of leg The inferior transverse ligament of the tibiofibular syndesmosis is included in older versions of ''Gray's Anatomy'', but not in ''Terminologia Anatomica''. However, it still appears in some anatomy textbooks. It should not be confused with the superior tibiofibular joint The proximal tibiofibular articulation (also called superior tibiofibular joint) is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula.

Talocrural
The ankle, or the talocrural region, or the jumping bone (informal) is the area where the foot and the leg meet. The ankle includes three joints: the ankle joint proper or talocrural joint, the subtalar joint, and the inferior tibiofibular joint. The movements produced at this joint are dorsiflexion and plantarflexion of the foot. In common usage, the term ankle refers exclusively to the ankle region. In medical terminology, "ankle" (without qualifiers) can refer broadly to the region or specifically to the talocrural joint. The main bones of the ankle region are the talus (in the foot), and the tibia and fibula (in the leg). The talocrural joint is a synovial hinge joint that connects the distal ends of the tibia and fibula in the lower limb with the proximal end of the talus. The articulation between the tibia and the talus bears more weight than that between the smaller fibula and the talus.

Ligaments
A ligament is the fibrous connective tissue that connects bones to other bones. It is also known as ''articular ligament'', ''articular larua'', ''fibrous ligament'', or ''true ligament''. Other ligaments in the body include the: * Peritoneal ligament: a fold of peritoneum or other membranes. * Fetal remnant ligament: the remnants of a fetal tubular structure. * Periodontal ligament: a group of fibers that attach the cementum of teeth to the surrounding alveolar bone. Ligaments are similar to tendons and fasciae as they are all made of connective tissue. The differences among them are in the connections that they make: ligaments connect one bone to another bone, tendons connect muscle to bone, and fasciae connect muscles to other muscles. These are all found in the skeletal system of the human body. Ligaments cannot usually be regenerated naturally; however, there are periodontal ligament stem cells located near the periodontal ligament which are involved in the adu ...

Superior Tibiofibular Joint
The proximal tibiofibular articulation (also called superior tibiofibular joint) is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula. The contiguous surfaces of the bones present flat, oval facets covered with cartilage and connected together by an articular capsule and by anterior and posterior ligaments. When the term ''tibiofibular articulation'' is used without a modifier, it refers to the proximal, not the distal (i.e., inferior) tibiofibular articulation. Clinical significance Injuries to the proximal tibiofibular joint are uncommon and usually associated with other injuries to the lower leg. Dislocations can be classified into the following five types: * Anterolateral dislocation (most common) * Posteromedial dislocation * Superior dislocation (uncommon, associated with shortened tibia fractures or severe ankle injuries) * Inferior dislocation (rare, associated with lengthened tibia fractures or avulsion of the foot, usua ...

Terminologia Anatomica
''Terminologia Anatomica'' is the international standard for human anatomical terminology. It is developed by the Federative International Programme on Anatomical Terminology, a program of the International Federation of Associations of Anatomists (IFAA). The second edition was released in 2019 and approved and adopted by the IFAA General Assembly in 2020. ''Terminologia Anatomica'' supersedes the previous standard, ''Nomina Anatomica''. It contains terminology for about 7500 human anatomical structures. Categories of anatomical structures ''Terminologia Anatomica'' is divided into 16 chapters grouped into five parts. The official terms are in Latin. Although equivalent English-language terms are provided, as shown below, only the official Latin terms are used as the basis for creating lists of equivalent terms in other languages.

Gray's Anatomy
''Gray's Anatomy'' is a reference book of human anatomy written by Henry Gray, illustrated by Henry Vandyke Carter, and first published in London in 1858. It has gone through multiple revised editions and the current edition, the 42nd (October 2020), remains a standard reference, often considered "the doctors' bible". Earlier editions were called ''Anatomy: Descriptive and Surgical'', ''Anatomy of the Human Body'' and ''Gray's Anatomy: Descriptive and Applied'', but the book's name is commonly shortened to, and later editions are titled, ''Gray's Anatomy''. The book is widely regarded as an extremely influential work on the subject. Publication history Origins The English anatomist Henry Gray was born in 1827. He studied the development of the endocrine glands and spleen and in 1853 was appointed Lecturer on Anatomy at St George's Hospital Medical School in London. In 1855, he approached his colleague Henry Vandyke Carter with his idea to produce an inexpensive and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inferior Transverse Ligament Of The Tibiofibular Syndesmosis
The inferior transverse ligament of the tibiofibular syndesmosis is a connective tissue structure in the lower leg that lies in front of the posterior ligament. It is a strong, thick band, of yellowish fibers which passes transversely across the back of the ankle joint, from the lateral malleolus to the posterior border of the articular surface of the tibia, almost as far as its malleolar process. This ligament projects below the margin of the bones, and forms part of the articulating surface for the talus. It is not included in Terminologia Anatomica ''Terminologia Anatomica'' is the international standard for human anatomical terminology. It is developed by the Federative International Programme on Anatomical Terminology, a program of the International Federation of Associations of Anatomis ..., but it still appears in some anatomy textbooks.

Interosseous Membrane Of Leg
The interosseous membrane of the leg (middle tibiofibular ligament) extends between the interosseous crests of the tibia and fibula, helps stabilize the Tib-Fib relationship and separates the muscles on the front from those on the back of the leg. It consists of a thin, aponeurotic joint lamina composed of oblique fibers, which for the most part run downward and lateralward; some few fibers, however, pass in the opposite direction. It is broader above than below. Its upper margin does not quite reach the tibiofibular joint, but presents a free concave border, above which is a large, oval aperture for the passage of the anterior tibial vessels to the front of the leg. In its lower part is an opening for the passage of the anterior peroneal vessels. It is continuous below with the interosseous ligament of the tibiofibular syndesmosis In anatomy, fibrous joints are joints connected by fibrous tissue, consisting mainly of collagen. These are fixed joints where bones are unit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Posterior Ligament Of The Lateral Malleolus
The posterior ligament of the lateral malleolus (posterior tibiofibular ligament, posterior inferior ligament) is smaller than the anterior ligament of the lateral malleolus and is disposed in a similar manner on the posterior surface of the syndesmosis In anatomy, fibrous joints are joints connected by fibrous tissue, consisting mainly of collagen. These are fixed joints where bones are united by a layer of white fibrous tissue of varying thickness. In the skull the joints between the bones are ....

Anterior Ligament Of The Lateral Malleolus
The anterior ligament of the lateral malleolus (anterior tibiofibular ligament or anterior inferior ligament) is a flat, trapezoidal band of fibers, broader below than above, which extends obliquely downward and lateralward between the adjacent margins of the tibia and fibula, on the front aspect of the syndesmosis. It is in relation, in front, with the fibularis tertius, the aponeurosis of the leg, and the integument; behind, with the interosseous ligament; and lies in wikt:contact, contact with the cartilage covering the talus bone, talus.

Talocalcaneal
In human anatomy, the subtalar joint, also known as the talocalcaneal joint, is a joint of the foot. It occurs at the meeting point of the talus and the calcaneus. The joint is classed structurally as a synovial joint, and functionally as a plane joint. Structure The talus is oriented slightly obliquely on the anterior surface of the calcaneus. There are three points of articulation between the two bones: two anteriorly and one posteriorly. The three articulations are known as facets, and they are the posterior, middle and anterior facets. * At the ''anterior and middle talocalcaneal articulation'', convex areas of the talus fits on to concave surfaces of the calcaneus. * The ''posterior talocalcaneal articulation'' is formed by a concave surface of the talus and a convex surface of the calcaneus. The sustentaculum tali forms the floor of middle facet, and the anterior facet articulates with the head of the talus, and sits lateral and congruent to the middle facet. In some ...

Cartilage
Cartilage is a resilient and smooth type of connective tissue. In tetrapods, it covers and protects the ends of long bones at the joints as articular cartilage, and is a structural component of many body parts including the rib cage, the neck and the bronchial tubes, and the intervertebral discs. In other taxa, such as chondrichthyans, but also in cyclostomes, it may constitute a much greater proportion of the skeleton. It is not as hard and rigid as bone, but it is much stiffer and much less flexible than muscle. The matrix of cartilage is made up of glycosaminoglycans, proteoglycans, collagen fibers and, sometimes, elastin. Because of its rigidity, cartilage often serves the purpose of holding tubes open in the body. Examples include the rings of the trachea, such as the cricoid cartilage and carina. Cartilage is composed of specialized cells called chondrocytes that produce a large amount of collagenous extracellular matrix, abundant ground substance that is rich in ...
