**Core Concept:** Meissner's corpuscle is a type of sensory receptor found in the skin, responsible for detecting pressure differences and light touch. It plays a crucial role in اللمس الخفيف (tactile) sensation.

**Why the Correct Answer is Right:** Meissner's corpuscle, also known as "touch receptors," is a specialized nerve cell located in the dermis layer of the skin. These corpuscles are responsible for detecting light touch, pressure, and vibration. They help the body to differentiate between different textures, pressures, and other tactile stimuli.

**Why Each Wrong Option is Incorrect:**

A. Meissner's corpuscle is not involved in detecting pain or heat. This is the function of other types of sensory receptors, such as Aδ and C fibers.

B. Although Meissner's corpuscle is involved in detecting light touch, it is not responsible for detecting temperature changes. This functionality lies within thermoreceptors, like thermoreceptors and thermo-neurons.

C. Meissner's corpuscle does not primarily detect noxious stimuli, like pain or tissue damage. Instead, it helps in detecting light touch, pressure, and vibration.

D. Meissner's corpuscle is not primarily involved in detecting proprioception (body position and movement). This is the function of the proprioceptors, which are located in the muscles, tendons, and joints.

**Clinical Pearl:** Meissner's corpuscle plays a vital role in the human body's ability to sense light touch and pressure, enabling us to feel the difference between smooth and rough surfaces, hard and soft objects, and even the direction and force of light touching.

**Correct Answer:** D. Meissner's corpuscle is primarily involved in detecting light touch, pressure, and vibration.
