Final answer:
Meissner's corpuscles are sensory receptors in the skin that specialize in detecting fine touch, low-frequency vibration, and pressure, predominantly located in the fingertips and eyelids.
Step-by-step explanation:
Meissner's corpuscles, also known as tactile corpuscles, are specialized sensory receptors that detect fine touch and pressure, as well as low-frequency vibration or flutter. These rapidly adapting mechanoreceptors are primarily located in the upper dermis, projecting into the epidermis and mostly found in the glabrous skin of the fingertips and eyelids. In terms of their density, these encapsulated neurons are more concentrated in the fingertips than in the palms, allowing for sophisticated discrimination of fine detail.
