Talk:Supraspinatus muscle

USMLE info in Action section
I think the following paragraph should be reworked, as it is relevant information, but most people will not know or care about what the USMLE is.
 * For USMLE step 1, know that the supraspinatus initiates abduction of the shoulder. Without a functioning supraspinatus, the physician must start abducting the patient's arm and eventually the patient will be able to finish abduction if the deltoid is functional, which is common because the supraspinatus is innervated by the suprascapular nerve from the superior/upper trunk of the brachial plexus. The deltoid is innervated more distally by the axillary nerve, which arises from the posterior cord of the brachial plexus. Cglion (talk) 12:57, 5 January 2013 (UTC)

Innervation section is too long
Why does it contain painstaking detail about excitation-contraction coupling? There is a separate, well-written article describing that phenomenon. — Preceding unsigned comment added by 50.5.87.21 (talk) 13:15, 16 February 2016 (UTC)
