 # The movement of bone in response to its own growth is termed as:

A. Rotation

B. Primary displacement

C. Secondary displacement

D. Differentiation

The correct answer is B. Primary displacement.

Displacement is described as the change in position of an object following the application of force. In this chapter, the term will be used for body tissues (namely, bone), and force is the growth of body tissues. The displacement of bones occurs with growth in two ways:

1. Primary displacement of a bone occurs due to its growth, which causes it to move from its original position. For example displacement of the chin anteriorly due to the increasing mandibular length.

2. Secondary displacement (also called translatory growth) is an illustration of growth at a location subsequent to actual growth occurring in a distant part of the skeletal system. The structure in question is displaced from its position due to- the growth of adjacent structures. For example, growth of the spheno-occipital synchondrosis leads to anterior displacement of the front maxillary complex.
