It was said that whenever pressure is placed upon a nerve it will always result in which outcome?

• A. Decreased function of that nerve
• B. Anesthesia
• C. Malposition of vertebra
• D. Pain

Answer: (A)

When a nerve is under pressure, its ability to transmit signals tends to decline. Mechanical compression can disrupt axonal transport, alter ion channel function, and impair blood flow to the nerve, all of which blunt conduction and reduce the nerve’s output. So the immediate and most consistent consequence is decreased function of the nerve, such as weaker signaling to muscles or reduced sensation distal to the site of pressure. Pain or anesthesia can occur but are not guaranteed in every case, and vertebral malposition isn’t a direct automatic result of nerve pressure.
