Sensory receptors in the dermis include: free nerve endings, pacinian corpuscles, and hair follicle receptors The mechanoreceptors of the skin are the meissner's corpuscles (which respond to light touch), the pacinian corpuscles (deeper in the dermis and respond to pressure), and the merkel's disks (closely related to the merkel's cells located in the epidermis and respond to light touch). The nociceptors are pain receptors that recognize hot, cold, and pain.
