摘要
本实验按照跨神经节溃变的原理,以酸性磷酸酶(AcP)法研究了大鼠桡神经、尺神经感觉纤维在脊髓胶状质内的定位投射。大鼠桡神经感觉纤维纵向投射,主要至脊髓C_6上段至T_1中段胶状质,尺神经主要投射至C_6中段至T_1中段胶状质。其横向投射,桡神经主要位于整个胶状质的中1/3区域;尺神经則均在胶状质中线以内,主要位于胶状质内侧半的外侧1/2~3/4区域。桡神经投射区居外,尺神经投射区居内。
The orientational projections of sensory fibres of radial nerve and ulnar nerve to the substantia gelatinosa(SG) of the spinal cord in rats were studied in accordance with the principle of transganglion degeneration by using the acid phosphatase technique.
It was found that the affeernt fibers of the radial nerve projected chiefly to SG, from the upper part of C_6 to the middle part of T_1 longitudinally; the ulnar nerves projected chiefly to SG from the middle part of C_6 to the middle part of T_1.
In their transverse projections,the afferent fibres of the radial nerve were mainly found in the region of the whole area of the middle 1/3 of SG; and the afferent fibres of ulnar nerve were found within the centre line of SG, and mainly in the region of the lateral 1/2~3/4 at medial half. In summary, radial nerve projected to the lateral region and ulnar nerve to the medial region of SG.
