Model innovation: hand skeleton with movable fingers this novel skeleton model allows through integrated joints to represent the agility of your fingers. The finger mechanism involves the joints between the individual members of the finger, the so called phalanges. It is hinge joints. These are divided as follows: the fingers consist, apart from the thumbs, three bones. To know more about this subject visit brokerage firm. These are called proximal, medial and distal phalanx. The thumb has only a proximal and distal phalanx.
Proximal phalanx of this bone is also known as the first joint of the finger. At the same time, he represents the longest phalanx. The metacarpal bones gives the finger metacarpophalangeal joint together with the end of the bone. Media phalanx, the middle finger bones called the second joint of the finger. At the lower end, it forms the so-called finger Middle joint (PIP) with the basic link. Above are two more small articular processes (DIP).
Distal phalanx of the last bone forms the end link and also third joint of the finger is called. It is the shortest finger bones. At the bottom, it’s bigger and along with the media phalanx, forms the Fingerendgelenk. The other end has a ridge of bone, which supports the nail bed. The pictured model can move the above joints and the finger mechanism can be vividly to demonstrate. Only the carpal bones are represented in one piece, to make the model stable.
