  • Radicular (radicularis) – total anesthesia in a zone of an innervation of a certain back root of a spinal cord;
  • Leprose (leprosa) – occurs at patients with a leprosy, arises because of specific damage of skin receptors; it is characterized by consecutive easing and loss at first temperature, then painful and, at last, tactile sensitivity at long preservation of proprioceptive;
