Mobile Muscle

I am enjoying mobile blogging. The main problem is I cannot link to other sites or add pictures with any ease.... ah well

Today's muscle is the subclavius. You have one of these under each clavicle (L/R). It lies underneath the pectoralis major in your chest. In some patients/clients this muscle being tight can cause restrictions in shoulder mobility. When this happens we (the PT or the patient) can mobilize the muscle (aka move it around) to loosen it up and get rid of that restriction.

The muscle originates on the 1st rib and costal cartilage.
It inserts on the inferior middle 1/3 of the clavicle.
It is innervated by a very well named nerve: 'the nerve to the subclavius'
It's actions are to:
1) Aid in respiration
2) Anchor and depress the clavicle
3) Prevent lateral displacement of the clavicle
