Left Hand Tendons Diagram. Percussion over the volar wrist crease produces electric sensation distally in the hand and wrist flexion with the elbow in extension produces thumb paresthesias within 18 seconds. It is located on the thumb side of the hand lying laterally in the lower arm parallel in reference to the ulna 1 2.
The median nerve originates from the lateral and medial cords of the brachial plexus and has contributions from ventral roots of c5 c7 lateral cord and c8 and t1 medial cord. Please note that the articular capsule has been removed in this diagram to show the inside of the knee joint. The flexor digitorum superficialis fds and flexor digitorum profundus fdp are the flexor tendons of the fingers and the flexor pollicis longus fpl is the only thumb flexor.
The length of tendons from the servo bed to the fingers extremity is a real torque eater.
And it can even occur in locations outside your abdomen. Even servos with a torque of 12kg have difficulty to reach their position. It is one of the five main nerves originating from the brachial plexus. Two one in each arm.
