Which term describes the movement of cytoplasm within axons that transports proteins, enzymes, mitochondria, and neurotransmitters?

• A. Nerve Compression
• B. Intervertebral Subluxation
• C. Axoplasmic Transport
• D. Facilitation

Answer: (C)

Axoplasmic transport is the process by which cytoplasm-filled axons move essential cargo along their length. This system shuttles proteins, enzymes, mitochondria, and neurotransmitters from the cell body toward the nerve terminals (anterograde) and can also move materials back toward the soma (retrograde). Motor proteins such as kinesin carry cargo along microtubule tracks for rapid delivery, while dynein handles retrograde movement. This transport system can be fast or slow, depending on the cargo and distance, ensuring neurons have the necessary components for signaling and maintenance. The other listed terms describe mechanical or clinical concepts rather than intracellular transport, so they don't describe the process.
