WebSensory receptors in the skin sense extreme temperature and the early signs of tissue damage. This triggers an action potential, which travels along the sensory fiber from the skin, through the dorsal spinal root to the spinal cord, and … Web2.2 Descending Motor Pathways. The reflex circuits demonstrate that sophisticated neural processing occurs at the lowest level of the motor hierarchy. These automatic reflexes can be modulated, however, by higher levels of the hierarchy. For example, when touching an iron to see if it is hot, your flexor reflex may be hypersensitive.
