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
Gliding ant ants to gain control of their falls more quickly. Many ants use long, flattened legs and wide, flanged heads to act as parachutes to control the direction of their descent, although controlled descent has also been observed in species of "Pseudomyrmecinae" that have more cylindrical bodies. Gliding is not observed in all arboreal ants. Some characteristics that may be evolutionarily correlated with gliding are: Gliding ant Gliding ants are arboreal ants of several different genera that are able to control the direction of their descent when falling from a tree. Living in the rainforest canopy like many other gliders, gliding
