A tactile stimulus applied to the EEC can reflexly cause the contralateral hip-thigh to flex at the hip joint and the leg to extend. Various stimuli, e.g., pressure, thermal or nociceptive, may also initiate the above reflex. The conjectured reflex is considered to be mediated via afferent fibers to the spinal tract and nucleus of the fifth cranial nerve, synapsing with the brainstem reticular core in the medulla and/or pons. The reticulospinal motor system descending in the spinal cord relays the afferent fibers to the contra lower limb appropriate musculature. The overt reflex is indeed rare.
施加于外胚层的触觉刺激可反射性地使对侧髋关节处的髋大腿屈曲,腿部伸展。各种刺激,如压力、热或伤害性刺激,也可能引发上述反射。推测该反射是通过传入纤维介导至脊髓束和第五脑神经核,在延髓和/或脑桥与脑干网状核心发生突触联系。脊髓中下行的网状脊髓运动系统将传入纤维传递至对侧下肢的相应肌肉组织。这种明显的反射确实很少见。
