This video shows the scalene muscles and describes their attachments and actions.
Scalenus Anterior O: C3 - C6 Transverse processes, anterior side I: First Rib A: Raise first rib, flex neck
O: C2 - C7 Transverse processes, posterior side I: First Rib A: Raise first rib, flex neck
O: C5 - C6 Transverse processes, posterior side I: Second Rib A: Raise second rib, flex neck
The scalenes raise the first two ribs, as in a forced inhalation, and they also help with neck flexion. They are frequently strained in whiplash accidents.
The brachial plexus originates form the nerve roots C5 - T1 and passes in between Scalenus Medius and Scalenus Anterior. Tightness in the scalene muscles can cause impingement on these nerves, causing symptoms of Thoracic Outlet Syndrome.
Symptoms of Thoracic Outlet Syndrome include parasthesia (pain, tingling, hypersensitivity or numbness) along the C-8 dermatome to the 4th and 5th fingers, arms going to sleep at night, and arms going to sleep when being held up or overhead.
The Massage Technique Library was recently rebuilt from the ground up. The new library is much faster and more secure than the previous versions. There is an improved search function, and an enhanced comment system. Soon there will be a way to save your favorite techniques in a favorites menu.
The library is currently free and open to the public, so please check it out while you can. No login or registration is necessary.
Soon the library will once again be for members only, with the exception of the free section.
We are not raising the price, so membership will continue to be only $7 per month or $72 per year. There will be a way to sign up for the library on May 10th. Current library members will have access to the library without signing up again but may need to reset their password.
With the rebuilding of over 800 interlinked pages with video content, there are bound to be some errors and glitches. Please let us know of any problems or concerns by using our contact form here. Your help is greatly appreciated.
I hope you enjoy the new library, and I look forward to your comments and suggestions.
