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.
Bell's palsy is a common cause of a facial palsy. Less commonly, facial palsy is caused by other things that can damage or affect the facial nerve. For example: a head injury, sarcoidosis, Lyme disease, growths in the ear, tumours in the parotid gland and tumours in the brain.
