Key Concepts

Peripheral Nervous System

The peripheral nervous system includes all nerves and ganglia outside the brain and spinal cord. It is responsible for connecting the central nervous system to limbs and organs, transmitting signals that control muscle movement and sensory perception. Conditions affecting this system generally involve nerve injury, compression, or inflammation, which can lead to localized symptoms.

Central Nervous System

The central nervous system consists of the brain and spinal cord, which serve as the main processing centers for the entire nervous system. Diseases of the central nervous system affect these areas and typically involve more widespread or systemic neurological dysfunction rather than the isolated nerve compression seen in peripheral disorders.

Nerve Compression

Nerve compression is a condition where nerves become pinched or pressed by surrounding tissues, leading to symptoms such as pain, numbness, or weakness. This mechanism is central to many peripheral neuropathies, highlighting the difference from central nervous system disorders, which involve intrinsic dysfunction of the brain or spinal cord.
