The bone hierarchy is a tree-like construction, with the foundation bone on the high of the chain. The foundation bone usually represents the hip or backbone, and it controls the motion of all the opposite bones within the hierarchy. Every bone within the hierarchy has a mum or dad bone and a number of little one bones. The mum or dad bone controls the motion of the kid bones, and the kid bones inherit the motion of their mum or dad bone.
The relationships between bones are outlined by joints. Joints permit bones to maneuver relative to one another, they usually decide the vary of movement for every bone. There are three major forms of joints within the human physique: ball-and-socket joints, hinge joints, and pivot joints. Ball-and-socket joints permit for a variety of movement, together with rotation, flexion, and extension. Hinge joints permit for motion in a single aircraft, reminiscent of bending and straightening.
