Talus Bone
The talus (; Latin for ankle or ankle bone), talus bone, astragalus (), or ankle bone is one of the group of foot bones known as the tarsus. The tarsus forms the lower part of the ankle joint. It transmits the entire weight of the body from the lower legs to the foot.Platzer (2004), p 216 The talus has joints with the two bones of the lower leg, the tibia and thinner fibula. These leg bones have two prominences (the lateral and medial malleoli) that articulate with the talus. At the foot end, within the tarsus, the talus articulates with the calcaneus (heel bone) below, and with the curved navicular bone in front; together, these foot articulations form the ball-and-socket-shaped talocalcaneonavicular joint. The talus is the second largest of the tarsal bones; it is also one of the bones in the human body with the highest percentage of its surface area covered by articular cartilage. It is also unusual in that it has a retrograde blood supply, i.e. arterial blood enters the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tarsus (skeleton)
In the human body, the tarsus is a cluster of seven articulating bones in each foot situated between the lower end of the tibia and the fibula of the lower leg and the metatarsus. It is made up of the midfoot (Cuboid bone, cuboid, medial, intermediate, and lateral cuneiform bone, cuneiform, and navicular) and hindfoot (Talus bone, talus and calcaneus). The tarsus articulates with the bones of the metatarsus, which in turn articulate with the proximal phalanges of the toes. The joint between the tibia and fibula above and the tarsus below is referred to as the ankle, ankle joint proper. In humans the largest bone in the tarsus is the calcaneus, which is the weight-bearing bone within the heel of the foot. Human anatomy Bones The talus bone or ankle bone is connected superiorly to the two bones of the lower leg, the tibia and fibula, to form the ankle, ankle joint or talocrural joint; inferiorly, at the subtalar joint, to the calcaneus or heel bone. Together, the talus and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetrahedral
In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has fewer than 5 faces. The tetrahedron is the three-dimensional case of the more general concept of a Euclidean simplex, and may thus also be called a 3-simplex. The tetrahedron is one kind of pyramid, which is a polyhedron with a flat polygon base and triangular faces connecting the base to a common point. In the case of a tetrahedron the base is a triangle (any of the four faces can be considered the base), so a tetrahedron is also known as a "triangular pyramid". Like all convex polyhedra, a tetrahedron can be folded from a single sheet of paper. It has two such nets. For any tetrahedron there exists a sphere (called the circumsphere) on which all four vertices lie, and another sphere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knucklebones
Knucklebones, also known as scatter jacks, snobs, astragalus, tali, dibs, fivestones, jacks, or jackstones, among many other names, is a game of dexterity played with a number of small objects that are thrown up, caught, and manipulated in various manners. It is ancient in origin and is found in various cultures worldwide. The name "knucklebones" is derived from the Ancient Greek version of the game, which uses the astragalus (a bone in the ankle, or hock) of a sheep. However, different variants of the game from various cultures use other objects, including stones, seashells, seeds, and cubes. Modern knucklebones consist of six points, or knobs, projecting from a common base and are usually made of metal or plastic. The winner is the first player to successfully complete a prescribed series of throws, which, though similar, differ widely in detail. The simplest throw consists in either tossing up one stone, the jack, or bouncing a ball and picking up one or more stones or kn ...

Joint Dislocation
A joint dislocation, also called luxation, occurs when there is an abnormal separation in the joint, where two or more bones meet.Dislocations. Lucile Packard Children’s Hospital at Stanford. Retrieved 3 March 2013 A partial dislocation is referred to as a subluxation. Dislocations are often caused by sudden trauma on the joint like an impact or fall. A joint dislocation can cause damage to the surrounding ligaments, tendons, muscles, and nerves. Dislocations can occur in any major joint (shoulder, knees, etc.) or minor joint (toes, fingers, etc.). The most common joint dislocation is a shoulder dislocation. Treatment for joint dislocation is usually by closed reduction, that is, skilled manipulation to return the bones to their normal position. Reduction should only be performed by trained medical professionals, because it can cause injury to soft tissue and/or the nerves and vascular structures around the dislocation. Symptoms and signs The following symptoms are common with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Talar Fractures
Talar :hy:Մշտադալար բույսեր, դալար is a Western Armenian name for females. It's meaning is symbolic of the Evergreen, Evergreen Tree. The talar or talaar ( fa, تالار) is the throne hall of the Persian Empire, Persian monarch that is open to the public. It includes a throne carved on the rock-cut tomb of Darius the Great, Darius at Naqsh-e Rostam, near Persepolis, and above the portico which was copied from his palace. The ''Talar Divan Khaneh'' built by Fath-Ali Shah Qajar, Fath Ali Shah is an example of this pavilion. Description In ancient times, as depicted in the sculptured facade of Darius tomb at Persepolis show, the talar had three tiers, with Atlant statues upholding each. This design typified the subject-people of the monarch. The talar built by the Qajar dynasty as part of the Royal Palace is a spacious chamber with flat ceiling decorated with mirror panels. The walls are also decorated with mirror work called ''aineh-kari'', which produce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uterus
The uterus (from Latin ''uterus'', plural ''uteri'') or womb () is the organ in the reproductive system of most female mammals, including humans that accommodates the embryonic and fetal development of one or more embryos until birth. The uterus is a hormone-responsive sex organ that contains glands in its lining that secrete uterine milk for embryonic nourishment. In the human, the lower end of the uterus, is a narrow part known as the isthmus that connects to the cervix, leading to the vagina. The upper end, the body of the uterus, is connected to the fallopian tubes, at the uterine horns, and the rounded part above the openings to the fallopian tubes is the fundus. The connection of the uterine cavity with a fallopian tube is called the uterotubal junction. The fertilized egg is carried to the uterus along the fallopian tube. It will have divided on its journey to form a blastocyst that will implant itself into the lining of the uterus – the endometrium, where it will ...

Interosseous Talocalcaneal Ligament
The interosseous talocalcaneal ligament forms the chief bond of union between the talus and calcaneus. It is a portion of the united capsules of the talocalcaneonavicular and the talocalcaneal joints, and consists of two partially united layers of fibers, one belonging to the former and the other to the latter joint. It is attached, above, to the groove between the articular facets of the under surface of the talus; below, to a corresponding depression on the upper surface of the calcaneus. It is very thick and strong, being at least 2.5 cm. in breadth from side to side, and serves to bind the calcaneus and talus firmly together. See also * Subtalar joint 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 bone, talus and the calcaneus. The joint is classed structurally as a synovial joint, and functional ...

Plantar Calcaneonavicular Ligament
The plantar calcaneonavicular ligament (also known as the spring ligament or spring ligament complex) is a complex of three ligaments on the underside of the foot that connect the calcaneus with the navicular bone. Structure The plantar calcaneonavicular ligamentous complex is a broad and thick band with three constituent ligaments. These connect the anterior margin of the sustentaculum tali of the calcaneus to the plantar surface of the navicular bone. Its individual components are the: * superomedial calcaneonavicular ligament. * medioplantar oblique ligament. * inferior calcaneonavicular ligament. These ligament components attach to different parts of the navicular bone. The dorsal or superomedial component of the ligament presents a fibrocartilaginous facet, lined by the synovial membrane, upon which a portion of the head of the talus rests. Its plantar surface, consisting of the intermedial and lateral ligaments, is supported by the tendon of the tibialis posterior; its ...

Os Trigonum
An accessory bone or supernumerary bone is a bone that is not normally present in the body, but can be found as a variant in a significant number of people. It poses a risk of being misdiagnosed as bone fractures on radiography. Wrist and hand Os ulnostyloideum The ''os ulnostyloideum'' is an ulnar styloid process that is not fused to the rest of the ulna bone.R. O'Rahilly. ''A survey of carpal and tarsal anomalies.'' J Bone Joint Surg Am. 1953; 35: 626–642 On X-rays, an ''os ulnostyloideum'' is sometimes mistaken for an avulsion fracture of the styloid process. However, the distinction between these is extremely difficult.T.E. Keats, M.W. Anderson. ''Atlas of normal roentgen variants that may simulate disease''. 7th edition, Mosby Inc. 2001 It is alleged that the os ulnostyloideum has a close relationship with or is synonymous with the os triquetrum secundarium.

Flexor Hallucis Longus Muscle
The flexor hallucis longus muscle (FHL) is one of the three deep muscles of the posterior compartment of the leg that attaches to the plantar surface of the distal phalanx of the great toe. The other deep muscles are the flexor digitorum longus and tibialis posterior; the tibialis posterior is the most powerful of these deep muscles. All three muscles are innervated by the tibial nerve which comprises half of the sciatic nerve. Structure The flexor hallucis longus is situated on the fibular side of the leg. It arises from the inferior two-thirds of the posterior surface of the body of the fibula, with the exception of 2.5 cm. at its lowest part; from the lower part of the interosseous membrane; from an intermuscular septum between it and the peroneus muscles, laterally, and from the fascia covering the tibialis posterior, medially. The fibers pass obliquely downward and backward, where it passes through the tarsal tunnel on the medial side of the foot and end in a tendon whic ...
