The bone hierarchy is a tree-like construction, with the basis bone on the prime of the chain. The basis 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 enable bones to maneuver relative to one another, they usually decide the vary of movement for every bone. There are three primary kinds of joints within the human physique: ball-and-socket joints, hinge joints, and pivot joints. Ball-and-socket joints enable for a variety of movement, together with rotation, flexion, and extension. Hinge joints enable for motion in a single airplane, equivalent to bending and straightening.
