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.
The radial nerve is also responsible for extending the wrist and fingers, and it controls sensation in part of the hand. Injury to the radial nerve may result in radial neuropathy, or radial nerve palsy.
