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 changing the format of the posts to include more extensive self-care, illustrations, therapist notes, anatomy, and protocols. We’d love your feedback. We are adding posts and converting the old posts as quickly as time permits.
