神经系统评估四、神经反射评估1、浅反射 为刺激皮肤和粘膜引起的反射。1

Nervous system evaluation <br>4. Neural reflex evaluation <br>1. The superficial reflex is the reflex caused by stimulating the skin and mucous membranes. <br>1) Corneal reflex Complete disappearance of corneal reflex is seen in deep coma patients. <br>2) Abdominal wall reflex <br>center: <br>upper: 7-8 segment of <br>thoracic cord: middle: 8-10 segment <br>of thoracic cord; lower: 11-12 segment of thoracic cord <br>Normal response: abdominal muscle contraction in the stimulated part. <br>Significance: <br>Absence of upper, middle, or lower reflexes is seen in lesions of the corresponding spinal cord segments; <br>decreased or absent reflexes on one side of the abdominal wall are seen in lesions of the ipsilateral pyramidal tract; <br>complete disappearance of reflexes on both sides of the abdominal wall is seen in coma and acute abdomen. <br>3) Cremaster reflex <br>center: 1-2 segment of lumbar spinal cord <br>normal response: ipsilateral cremaster muscle contraction, testis lift. <br>significance:

Nervous system evaluationIV. Nerve reflex assessment1. Shallow reflection is the reflection caused by skin and mucous membrane irritation.1) Corneal reflex The complete disappearance of corneal reflex can be seen in patients with deep coma.2) Abdominal wall reflexCenter:Upper: 7-8 segments of thoracic spinal cord:Medium: 8-10 segments of thoracic spinal cord;Inferior: 11-12 segments of thoracic spinal cordNormal reaction: Abdominal muscles of the stimulated part contract.Meaning:The disappearance of the upper, middle or lower reflex was found in the lesions of the corresponding spinal cord segments.One side of abdominal wall reflex weakened or disappeared in the lesion of ipsilateral pyramidal tract;Complete disappearance of bilateral abdominal wall reflex can be seen in coma and acute abdomen.3) Testicular reflexCenter: 1-2 segments of lumbar spinal cord.Normal reaction: Contraction of the ipsilateral cremaster and lifting of the testicles.Meaning:
