extensor digitorum

a muscle of the posterior forearm. It divides distally into four tendons that pass under the extensor retinaculum and diverge on the back of the hand, inserting into the second and third phalanges of the medial four fingers. It functions to extend the phalanges and, by continued action, the wrist. Also called extensor digitorum communis.

Excisions of the extensor digitorum brevis (EDB) muscles were performed pre- and post-treatment with ataluren on all subjects, and immunofluorescence images were analyzed qualitatively and quantitatively.
The MeCFES recorded the myoelectric activity from the 2/3 proximal part of the forearm at the level of innervation zones of extensor carpi radialis, extensor carpi ulnaris, and/or extensor digitorum communis as appropriate for the residual volitional activity of the patient.
Sports scientists took two different types of mouse muscle - a leg muscle called extensor digitorum longus, as well as diaphragm muscle - and tested how they performed when dosed with 70 micromolars of caffeine - equivalent to "a couple of espressos," said first author Jason Tallis, a muscle physiologist at Coventry University in England.
On the other hand, Fx increased GLUT4 expression levels in the extensor digitorum longus (EDL) muscle, although GLUT4 translocation tended to increase.
