frigidoreceptor
Extremely low (Highly specialized scientific/medical term)Technical/Scientific
Definition
Meaning
A sensory receptor in the skin and mucous membranes that detects cold temperatures.
A specialized nerve ending (often a free nerve ending) that responds specifically to decreases in temperature, playing a key role in thermoregulation and the perception of cold.
Linguistics
Semantic Notes
This term is almost exclusively used in physiology, neurology, and sensory biology. It is a compound of 'frigido-' (Latin: cold) and 'receptor'. Not to be confused with 'thermoreceptor', which is the broader category encompassing both cold and heat detectors.

Examples
By Part of Speech
adjective
British English
- The frigidoreceptive pathway was mapped.
- Frigidoreceptor signalling is complex.
American English
- The frigidoreceptive pathway was mapped.
- Frigidoreceptor signaling is complex.
Examples
By CEFR Level
- The skin has different receptors, including frigidoreceptors for cold.
- When you touch ice, your frigidoreceptors send a signal to your brain.
- The study aimed to characterise the ion channels specific to cutaneous frigidoreceptors.
- Frigidoreceptor discharge frequency increases logarithmically with the intensity of the cold stimulus.
Learning
Memory Aids
Mnemonic
Think: 'Frigid' (like a fridge) + 'receptor' = a receptor for frigid/cold temperatures.
Conceptual Metaphor
SENSORS ARE SENTINELS (Frigidoreceptors act as sentinels guarding against cold).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as 'холодный рецептор' in formal scientific writing; the established term is 'холодовой рецептор' or 'терморецептор, чувствительный к холоду'.
Common Mistakes
- Misspelling as 'frigidorecepter' (US) or 'fridgidoreceptor'.
- Using it in a non-scientific context.
- Confusing it with 'nociceptor' (pain receptor), as extreme cold can also trigger pain.

FAQ
Frequently Asked Questions
No, it is a highly specialised term used almost exclusively in scientific literature related to physiology and sensory systems.
A thermoreceptor is the general category for temperature-sensitive receptors. A frigidoreceptor is a specific type of thermoreceptor that responds only to cold stimuli.
They are primarily found in the skin (cutaneous) and mucous membranes (e.g., in the mouth and cornea).
In less technical contexts or general explanation, 'cold receptor' is a perfectly understandable synonym. 'Frigidoreceptor' is the precise, formal term.
