ruffini's corpuscle
Very lowTechnical/scientific
Definition
Meaning
A type of sensory receptor in the skin that responds to stretch and sustained pressure.
Ruffini's corpuscle is a slow-adapting mechanoreceptor found in the dermis and subcutaneous tissue, involved in proprioception and detecting skin deformation.
Linguistics
Semantic Notes

Examples
By CEFR Level
- Ruffini's corpuscle is in the skin.
- Ruffini's corpuscles help us feel when our skin is stretched.
- The function of Ruffini's corpuscle is to detect sustained pressure and skin stretch.
- In neurophysiology, Ruffini's corpuscles are classified as slow-adapting type II mechanoreceptors critical for proprioception.
Learning
Memory Aids
Mnemonic
Think of 'Ruffini' as 'rough-in' the skin, helping you feel when it's stretched or rough pressure.
Conceptual Metaphor
A stretch detector in the skin's sensory network, akin to a tension sensor.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing 'corpuscle' with 'корпускула' which can mean particle; in anatomy, it's often translated as 'тельце Руффини'.
- Ensure proper transliteration of 'Ruffini' to maintain accuracy.
Common Mistakes
- Misspelling as 'Ruffin's corpuscle' or 'Ruffini corpusle'.
- Mispronouncing 'Ruffini' with a hard 'u' sound or 'corpuscle' with emphasis on the second syllable.

FAQ
Frequently Asked Questions
It is a sensory receptor in the skin that detects stretch and sustained pressure, named after Angelo Ruffini.
Primarily in the dermis and subcutaneous tissue of the skin, especially in areas like the fingertips and joints.
It is slow-adapting, meaning it continues to respond to sustained stimuli, unlike fast-adapting receptors like Meissner's corpuscles.
Yes, it is present in many vertebrates and plays a similar role in tactile sensation and proprioception.
