The skin is innervated by somatosensory neurons that project to the spinal cord. A-fibres, such as those that innervate Merkel cells and those around hair shafts, are though to be touch receptors. A-fibres and C-fibres include thermoreceptors and nociceptors. A-fibres terminate in the dermis. Peptidergic and non-peptidergic C-fibres terminate in different epidermal layers59 and have different projection patterns to the spinal cord
