Final answer:
The sensory nerve endings of the skin include free nerve endings, Meissner's corpuscles, Merkel cells, Pacinian corpuscles, root hair plexuses, and Ruffini corpuscles. Each type of sensory receptor responds to different kinds of touch-related stimuli.
Step-by-step explanation:
The sensory nerve endings of the skin include free nerve endings, Meissner's corpuscles, Merkel cells, Pacinian corpuscles, root hair plexuses, and Ruffini corpuscles. Each type of sensory receptor responds to different kinds of touch-related stimuli. Free nerve endings respond to pain and temperature variations, Merkel cells are associated with light touch and texture discrimination, Meissner's corpuscles respond to light touch, Pacinian corpuscles detect vibration, root hair plexuses sense movement of hair, and Ruffini corpuscles respond to skin stretch.
