DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell.
Radial nerve palsy. Radial nerve palsy in the arm most commonly is caused by fracture of the humerus, especially in the middle third (Holstein-Lewis fracture) or at the junction of the middle and distal thirds. The nerve may be compressed by the lateral intermuscular septum.
Types include: 1  Ulnar nerve compression at the wrist: This causes numbness and tingling of the little finger, part of the ring finger, and in the palm on the little finger side. 2  Ulnar nerve compression at the elbow: This causes not only the numbness noted above but also numbness on the back of the hand on the pinky side. Pressure on the radial nerve in the forearm or above the wrist: This can cause numbness over the back of the thumb, the index finger, and the web between these two fingers. Median nerve compression at the elbow: This can cause numbness not only in the same area as in carpal tunnel syndrome but also in the palm at the base of the thumb.
