nerve fibre
C2technical, academic
Definition
Meaning
A long, slender projection (axon) of a neuron that conducts electrical impulses away from the neuron's cell body.
The basic structural and functional unit of a nerve, responsible for transmitting signals throughout the nervous system. In a non-scientific context, it can metaphorically refer to one's capacity for endurance or sensitivity.
Linguistics
Semantic Notes
Primarily a biological/anatomical term. The term 'fiber' (US) or 'fibre' (UK) refers to the thread-like structure.
Dialectal Variation
British vs American Usage
Differences
Spelling: 'fibre' (UK) vs. 'fiber' (US). There is no difference in meaning or usage.
Connotations
None; purely technical.
Frequency
Equally common in medical/biological contexts in both regions. Rare in everyday speech.

Memory Aids
Mnemonic
Imagine a FIBRE-optic cable made of NERVous tissue, transmitting signals instead of light.
Conceptual Metaphor
INFORMATION TRANSMISSION IS A THREAD/CABLE; THE NERVOUS SYSTEM IS A COMMUNICATION NETWORK.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation like 'нервное волокно' for metaphorical contexts; it sounds overly biological. Use 'нервы' or 'выдержка' instead.
- Do not confuse with 'muscle fibre' (мышечное волокно).
Common Mistakes
- Misspelling: 'nerve fiber' in UK context or 'nerve fibre' in US academic writing (though often accepted).
- Using it as a synonym for 'nerve' (a nerve is a bundle of many nerve fibres).

FAQ
Frequently Asked Questions
No. A nerve is like a cable containing hundreds or thousands of individual nerve fibres (axons).
Motor nerve fibres carry commands from the brain and spinal cord to muscles and glands. Sensory nerve fibres carry information from sensory receptors (e.g., in skin, eyes) to the brain and spinal cord.
It follows the general spelling convention: UK English uses '-re' (fibre, centre), while US English uses '-er' (fiber, center).
