Hinge joint best examples of ginglymoid joints are the Interphalangeal joints of the hand and those of the foot and the joint between the humerus and ulna. The knee joints and ankle joints are less typical, as they allow a slight degree of rotation or of side-to-side movement in certain positions of the limb. The knee is the largest hinge joint in the human body. Hinge and pivot joints are both types of synovial joint. A hinge joint can be considered a modified sellar/saddle joint, with reduced movement. Other objects that work like hinged joints are door hinges, closet doors, and dog
Bacterial gliding large macromolecular assemblies located on the bacterium's cell body, while yet another utilize "focal adhesion complexes" and "treadmilling" of surface adhesins distributed along the cell body. The gliding motility of "Flavobacterium johnsoniae" uses a helical track superficially similar to "M. xanthus", but via a different mechanism. Here the adhesin SprB is propelled along the cell surface (spiraling from pole to pole), pulling the bacterium along 25 times faster than "M. xanthus". "Flavobacterium johnsoniae" move via a screw-like mechanism and are powered by a proton motive force. Bacterial gliding Bacterial gliding is a process of motility whereby a bacterium can move
