In humans, along the axons of Lissauer's tract temperature or pressure sensations enter the spinal cord. The Lissauer's tract will synapse on first-order neurons in grey matter of the dorsal horn, one or two vertebral levels up. The axons of these second-order neurons then decussate, joining the spinothalamic tract as they ascend to neurons in the ventral posterolateral nucleus of the thalamus. In mammals, temperature receptors innervate various tissues including the skin (as cutaeneous … WebbFree nerve endings called nociceptors in the skin have a high threshold for mechanical, chemical, or thermal stimuli and respond only when the intensity of these stimuli is high enough to damage tissue. We perceive the input from these receptors as pain. Superficial pain that arises from the skin has two components.

Temperature-sensitive neurons are also present in the hypothalamus, spinal cord, great vessels, and abdominal viscera.
