{"type":"rich","version":"1.0","title":"PART II: POSTERIOR MUSCLES (Figure 10.17) \nThese muscles of the posterior fascia' compartment are listed from the lateral to the medial aspect. They are inserts solely into radius all innervated by the radial nerve or its branches. More than half of the posterior compartment muscles arise from a common extensor origin tendon attached to the posterior surface of the lateral epicondyle of the humerus and adjacent fascia. The extensor tendons are held in place at the posterior aspect of the hand by the extensor retinaculum, which prevents \"bowstringing\" of these tendons when the wrist hyperextended. The extensor muscles of the fingers end in a broad hood over the dorsal side of the digits, the extensor expansion. \n( SEPERFICIAL MUSCLES )","provider_name":"Coggle","provider_url":"https://coggle.it","thumbnail_url":"https://static.coggle.it/diagram/YemHiVFgeBbmA7Qx/thumbnail","width":1920,"height":1200,"html":""}
