This chapter examines some of the basic human anatomy and neurobiology related to the perception of pain. In this context we will discuss how the nervous, endocrine, and musculoskeletal/fascial systems all contribute to our experience of this important sensation. We will look at some of the pathologic changes that occur when short-term pain becomes a long-term problem, and how stress can exacerbate pain perception. Finally, we will discuss how manual therapies may access peripheral nervous system structures in order to address some of the factors that can contribute to chronic pain patterns.
