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.

Classic examples of superficial reflexes include the abdominal reflex, the cremaster reflex and the normal plantar response.

Superficial reflexes are hypoactive at and below the level of the lesion and normal above.

脊神经浅反射：感觉信号—〉脊髓—〉大脑—〉脊髓—〉肌肉收缩。此弧的传入信号要通过脊髓到达大脑， 传出信号也要经过脊髓到达肌肉。在截瘫病人中，由于脊髓的损伤， 中断了此反射弧在脊髓内的上行AND/OR下行传导通路，所以用“废弃神经“来建立肖氏弧是不可能成功的。
