(c)
Nociceptors (itch and pain) and thermoreceptors are bare nerve endings. The receptive fields vary across the skin being smallest in the most distal regions ( fingertips, lips). Sensory information from the skin reaches the brain several pathways most notably the dorsal column pathway and the spinothalamic tract.
