Verified step by step guidance

Begin by understanding the different types of mechanoreceptors involved in the sense of touch. These include Ruffini endings, Pacinian corpuscles, Merkel discs, and Meissner's corpuscles.

Ruffini endings are responsible for detecting skin stretch and sustained pressure, contributing to the perception of object manipulation.

Pacinian corpuscles are specialized for detecting deep pressure and high-frequency vibration, often found in deeper layers of the skin.

Merkel discs are sensitive to light touch and texture, providing information about shapes and edges.

Meissner's corpuscles are located near the surface of the skin and are responsible for detecting light pressure and low-frequency vibration, making them crucial for the sense of touch, especially in areas like fingertips.
