Second Metatarsal Bone
The second metatarsal bone is a long bone in the foot. It is the longest of the metatarsal, metatarsal bones, being prolonged backward and held firmly into the recess formed by the three cuneiform bones. The second metatarsal forms joints with the Phalanges of the foot, second proximal phalanx (a bone in the second toe) through the metatarsophalangeal joint, the cuneiform bones, third metatarsal bone, third metatarsal and occasionally the first metatarsal bone. Structure Like the four other metatarsal bones, it can be divided into three parts: base, body and head. The base is the part closest to the ankle and the head is closest to the big toe. The narrowed part in the middle is referred to as the body of the bone. The bone is somewhat flattened, giving it two sides: the plantar (towards the Sole (foot), sole of the foot) and the dorsal side (the area facing upwards while standing). Its base is broad above, narrow and rough below. It presents four articular surfaces: one behind, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Bone
The long bones are those that are longer than they are wide. They are one of five types of bones: long, Short bone, short, Flat bone, flat, Irregular bone, irregular and Sesamoid bone, sesamoid. Long bones, especially the femur and tibia, are subjected to most of the load during daily activities and they are crucial for skeletal mobility. They grow primarily by elongation of the diaphysis, with an epiphysis at each end of the growing bone. The ends of epiphyses are covered with hyaline cartilage ("articular cartilage"). The longitudinal growth of long bones is a result of endochondral ossification at the epiphyseal plate. Bone growth in length is stimulated by the production of growth hormone (GH), a secretion of the Anterior pituitary, anterior lobe of the pituitary gland. The long bone category includes the femora, tibiae, and fibulae of the legs; the humerus, humeri, Radius (bone), radii, and ulnae of the arms; metacarpals and metatarsals of the hands and feet, the Phalanx bone ...

Lisfranc Joint
The tarsometatarsal joints (Lisfranc joints) are arthrodial joints in the foot. The tarsometatarsal joints involve the first, second and third cuneiform bones, the cuboid bone and the metatarsal bones. The eponym of Lisfranc joint is 18th-19th century surgeon and gynecologist, Jacques Lisfranc de St. Martin. Structure Bones The bones entering into their formation are the first, second, and third cuneiforms, and the cuboid bone, which articulate with the bases of the metatarsal bones. The first metatarsal bone articulates with the first cuneiform; the second is deeply wedged in between the first and third cuneiforms articulating by its base with the second cuneiform; the third articulates with the third cuneiform; the fourth, with the cuboid and third cuneiform; and the fifth, with the cuboid. The bones are connected by dorsal, plantar, and interosseous ligaments. Dorsal ligaments The dorsal ligaments are strong, flat bands. The first metatarsal is joined to the first cuneif ...

David Beckham
David Robert Joseph Beckham (; born 2 May 1975) is an English former professional footballer, the current president and co-owner of Inter Miami CF and co-owner of Salford City. Known for his range of passing, crossing ability and bending free-kicks as a right winger, Beckham has been hailed as one of the greatest and most recognisable midfielders of his generation, as well as one of the best set-piece specialists of all time. He is the first English player to win league titles in four countries: England, Spain, the United States and France. Beckham's professional club career began with Manchester United, where he made his first-team debut in 1992 at age 17. With United, he won the Premier League title six times, the FA Cup twice, and the UEFA Champions League in 1999. He then played four seasons with Real Madrid, winning the La Liga championship in his final season with the club. In July 2007, Beckham signed a five-year contract with Major League Soccer club LA Galaxy. Wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
