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.
Other, less common causes of radial nerve palsy in the arm include compression at the fibrous arch of the lateral head of the triceps and compression by an accessory subscapularis-teres-latissimus muscle.
Etiology. Third cranial (oculomotor) nerve disorders that cause palsies and affect the pupil commonly result from aneurysms (especially of the posterior communicating artery) and transtentorial brain herniation (see Brain herniation. ) and less commonly from meningitis affecting the brain stem (eg, TB meningitis).The most common cause of palsies that spare the pupil, particularly partial palsies, is ischemia of the 3rd cranial nerve (usually due to diabetes or hypertension) or of the midbrain.Occasionally, a posterior communicating artery aneurysm causes oculomotor palsy and spares the pupil. and less commonly from meningitis affecting the brain stem (eg, TB meningitis).
