Lecture Outline

CHAPTER OVERVIEW: This chapter describes and defines articulations, and analyzes movement at joints based on both the bony and soft tissue structures present at a joint. The anatomical features of different types of joints are described in detail. The types of body movements are discussed in general and in relation to the joints at which they normally occur.

IMPORTANT CONSIDERATIONS: The names of specific structures and parts of joints is best studied when the students can manipulate models and get a spatial sense for how the joints are constructed. This material can be combined with the material on the skeleton, so that the bones and their articulations are mentioned together. This material has two different logical splits. One split correlating joint structure and body movements and another between the general principles and the specific examples.
