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.
