Thoracic Outlet – Functional Anatomy

This is a short video walking through the structures from posterior to anterior followed by a more detailed document of the same structures.

This post on the anatomy of the scalene muscles is worth reviewing for its information about the frequency and types of anomalies in those muscles.

This video uses the convention throughout the site of bones of origin in blue, bones of insertion in green and bones that are trapped in tan. That makes for an interesting perspective on how the bones and structures interact.

These therapy notes are worth reviewing the palpation, trigger point patterns, and surrounding anatomy. It is particularly to look at how similar serratus posterior superior and iliocostalis cervicis are to the scalenes. They are often overlooked in cases of lower cervical compression.


This site is undergoing changes. Starting in early 2020, we began improving the format. We are also adding more extensive self-care, illustrations, therapist notes, anatomy, and protocols. We appreciate your input and feedback. You will see us adding posts and updating older posts as time permits.

This post is about the watershed moment that changed the direction of my bodywork. People would say that it is about treating at the source. I’d say that it is about understanding the governors and accessories in a pattern. This gives the therapist and client choices on how to plan on treating for relief or treating to create a body that is self-correcting.

Tony Preston has a practice in Atlanta, Georgia where he sees clients. He has written and taught about anatomy, trigger points, and cranial therapies since the mid-90s.
