With the third pick in the 2009 NBA Draft, the Oklahoma City Thunder select James Harden.
The nervous system is divided into the peripheral nervous system and the central nervous system. Fortunately, damaged peripheral nerves can regenerate after injury. However, the optic nerve and the spinal cord are in the central nervous system, and unfortunately cannot regenerate after injury.This is thought to be a result of inhibitory factors that are produced by cells that normally support the nerve fibers.n goldfish, the optic nerve can regenerate after injury. Molecular factors involved in structural support, gene regulation, and nerve fiber growth are produced in the goldfish optic nerve after injury.
1 Damage to the optic tract, which is behind (posterior) to the chiasm, causes loss of the entire visual field from the side opposite the damage (so if the left optic track is cut, there is a loss of vision from the entire right visual field).s a consequence, the fibers of the optic nerve are covered with myelin produced by oligodendrocytes, rather than Schwann cells of the peripheral nervous system, and are encased within the meninges. Peripheral neuropathies like Guillain-Barre barrÃ© syndrome do not affect the optic. nerve
