The extensor pollicis longus muscle begins at the ulna and the interosseous membrane, a tough fibrous tissue that connects the ulna and the radius in the lower arm.It is a skeletal muscle and is controlled by the motor nervous system.ts fibers are striated, which means they are arranged in parallel.
