Which type of sensory structures carrying the touch sensations are present in papillae extending into ridges of the fingertips___________________?

Explanation

Meissner's corpuscles lie in the dermal papillae of sensitive skin, including the ridges of the fingertips, and detect fine or light touch. Their superficial position makes them suitable for detecting small movements across the skin. The likely alternative is Pacinian corpuscles, but those are deeper and specialize in vibration and deep pressure.
