Definitions |
Superficial reflexes are motor responses to scraping of the skin. They are graded simply as present or absent, although markedly asymmetrical responses should be considered abnormal as well. These reflexes are quite different from the muscle stretch reflexes in that the sensory signal has to not only reach the spinal cord, but also must ascend the cord to reach the brain. The motor limb then has to descend the spinal cord to reach the motor neurons. As can be seen from the description, this is a polysynaptic reflex. This can be abolished by severe lower motor neuron damage or destruction of the sensory pathways from the skin that is stimulated. However, the utility of superficial reflexes is that they are decreased or abolished by conditions that interrupt the pathways between the brain and spinal cord (such as with spinal cord damage). |
