Okay, let's tackle this question. The user wants to know which receptor is responsible for sensing vibration. Hmm, I need to recall the different types of sensory receptors and their functions.

First, I remember that there are various types of mechanoreceptors in the skin. Meissner's corpuscles are sensitive to light touch and low-frequency vibrations, right? Then there's Pacinian corpuscles, which detect high-frequency vibrations and pressure. Ruffini endings are more for stretch and warmth, I think. And Merkel cells are for sustained pressure and texture.

Wait, the question is about vibration. So between Meissner and Pacinian. Meissner's are more for lower frequencies, like around 10-50 Hz, while Pacinian corpuscles respond to higher frequencies, maybe 50-500 Hz. So if the question is about vibration in general, maybe the answer is Pacinian? Or does it depend on the context? Let me check some sources. Oh, right, vibration is typically sensed by Pacinian corpuscles. They have a lamellar structure that allows them to respond to rapid changes in pressure, which is what vibration is. So the correct answer should be Pacinian corpuscles.

Now, looking at the options. The user didn't provide the options, but the correct answer is likely option C or D. But since the options are missing, I'll proceed with the explanation based on the receptors involved. The other options would include Meissner, Ruffini, Merkel, etc. Each of these has different functions, so they can be ruled out accordingly.

The key point here is the type of vibration each receptor detects. Meissner is for lower frequency, Pacinian for higher. Also, their locations differ: Pacinian in deeper layers, Meissner in dermal papillae. So in a clinical context, understanding these receptors helps in diagnosing sensory deficits. For example, damage to Pacinian corpuscles might affect the ability to sense high-frequency vibrations, which could be tested in a neurological exam.

**Core Concept**
Vibration sensation is primarily mediated by **Pacinian corpuscles**, a type of mechanoreceptor in the skin and deeper tissues. These receptors detect **high-frequency vibrations (50–500 Hz)** via their encapsulated, lamellar structure, which transmits mechanical energy into electrical signals through **stretch-activated ion channels**.

**Why the Correct Answer is Right**
Pacinian corpuscles are specialized for rapid adaptation to **high-frequency vibrations** due to their layered (lamellar) structure. When vibratory stimuli deform the layers, **mechanogated sodium channels** open, depolarizing the sensory neuron. This mechanism is distinct from other receptors like Meissner’s corpuscles (low-frequency vibrations) or Merkel cells (static pressure). Their deep dermal/subcutaneous location allows them to sense vibrations transmitted through bones and joints.

**Why Each Wrong Option is Incorrect**
**Option A:** Meissner’s corpuscles detect **low-frequency vibrations (10–50 Hz)** and light touch, not high-frequency vibrations.
**Option B:** Ruffini endings sense **skin stretch and joint position**, not vibration.
**Option D:** Merkel cells are **slow-adapting receptors** for sustained pressure and texture, not dynamic stimuli like vibration.
