Study Notes

The central nervous system (CNS) is protected by physical and chemical barriers.
The brain and spinal cord are surrounded by tough meningeal membranes and enclosed in bones.
The blood-brain barrier prevents most chemicals from entering the CNS.
Damage to the CNS has more serious consequences than damage to the peripheral nervous system (PNS).
Nerves can be damaged by physical trauma, swelling, or bruises.
Peripheral neuropathy can be caused by genetic, metabolic, inflammatory, infectious, or toxic conditions.
Nerves can temporarily lose function due to mechanical pressure, temperature changes, or chemical interactions.
Spinal cord injuries can result in loss of sensation or movement.
Scar tissue in the spinal cord prevents nerve fibers from regrowing.
CNS protections make it less susceptible to damage, but damage can have serious consequences.
