Sindesmology (the study of the compounds bones)

Bones as organs presents man as a single functional system related to passive locomotor apparatus. Form and type of connections bones you can imagine the amount of movements and thereby to judge about the functional features of the musculoskeletal system.
Connection of performing multiple functions, for example, the function of bone growth in length and width. In connection fade jerks and shocks, aided by a layer of various connective tissue, located on the surfaces in contact bones. Force of tremors with a magnitude of weakened in all kinds of connections, but especially in the joints. This is because the distribution of the pressure is perpendicular to the occurrence, i.e., the length of the body, and the position of the joints can be different, so the smaller the angle of the knee joint is, the weaker the concussion. In the function binding the individual bones in a single human skeleton participate not only ligaments, but also the tone of striated muscles, which reduced develop force 6-8 kg per 1 cm2 square joint. As the capsule joints forms a hermetic cavity with a negative pressure, in these conditions, the atmospheric pressure has a binding effect. In strengthening of joints involved the skin, subcutaneous tissue and fascia.
All connections in the human body are divided into three groups: continuous (synarthrosis), polusustavy (hemiarthrosis) and discontinuous (subtalar).
