초록

이 연구는 한국성인 시신의 팔신경얼기 6쪽에서 팔신경얼기의 말단가지를 구성하는 각 척수신경의 양을 정량화하는 데 목적이 있다. 팔신경얼기의 가지부분에서 분지하는 신경으로 등쪽어깨신경은 C5으로 구성되었고 참여하는 신경섬유 개수는 355±180개였고 긴가슴신경은 C5, C6, C7으로 구성되었고 C6에서 참여하는신경섬유가 743±346개로 가장 많았다.
줄기부분에서 분지하는 신경으로 빗장밑근신경은 C5로 구성되었고 참여하는 신경섬유는 242±71개였으며어깨위신경은 C5와 C6로 구성되었고 C5에서 참여하는 신경섬유가 1,942±505로 더 많았다.
신경다발의 몸쪽부분에서 분지되는 신경으로 가쪽가슴근신경은 C5, C6 그리고 C7으로 구성되었으며 C7에서참여하는 신경섬유가 2,917±785개로 가장 많았고 안쪽가슴근신경은 C8과 T1으로 구성되었으며 C8에서 참여하는 신경섬유가 964±430개로 더 많았다. 위어깨밑신경은 C5와 C6로 구성되었으며 C5에서 참여하는 신경섬유가 1,179±92개로 더 많았고 아래어깨밑신경은 C5, C6 그리고 C7으로 구성되었으며 C6에서 참여하는 신경섬유가 1,070±390개로 가장 많았고 가슴등신경은 C6, C7 그리고 C8으로 구성되었고 C7에서 참여하는 신경섬유가 2,335±324개로 가장 많았다.
신경다발의 먼쪽에서 분지되는 말단신경으로 근육피부신경은 C5, C6 그리고 C7으로 구성되었으며 C6에서참여하는 신경섬유가 4,009±1,883개로 가장 많았고 정중신경은 C5에서 T1으로 구성되었으며 C7에서 참여하는 신경섬유가 9,651±2,663개로 가장 많았다. 자신경은 C7, C8, T1으로 구성되었으며 C8에서 참여하는 신경섬유가 10,075±1,473개로 가장 많았으며 안쪽위팔피부신경과 안쪽아래팔피부신경은 모두 C8과 T1으로 구성되었으며 T1에서 참여하는 신경섬유가 각각 1,752±390개와 3,080±1,140개로 더 많았다. 노신경은 C5에서 T1으로 구성되었으며 C7에서 참여하는 신경섬유가 7,958±2,333개로 가장 많았으며 겨드랑신경은 C5와 C6로 구성되며 C5는 3,229±434개, C6는 3,255±1,177개로 비슷한 참여량을 보였다. 이 결과는 신경의 손상의 예측이나신경이식 등 임상적 시술에 적용할 수 있을 것으로 생각한다.

영어초록

This study was carried out to evaluate the quantity of the nerve fiber of the terminal branches of the typical brachial plexus in the 6 sides of the Korean adults.
The dorsal scapular nerve, which is derived from ramus of the brachial plexus, was comprised of C5 and participating nerve fiber was 355±180. The long thoracic nerve was composed of C5, C6 and C7, and was mainly originated from C6, and participating nerve fiber was 743±346. The nerves, which are branched out from trunk, nerve to subclavius muscle was composed of C5 and participating quantity was 242±71. The suprascapular nerve was comprised of C5 and C6, and the nerve fiber was mainly derived from C5 (1,942±505). The nerve, which is originated from proximal portion of the cord, the lateral pectoral nerve was constituted of C5, C6 and C7. The main component was C7 as the 2,917±785 nerve fiber. The medial pectoral nerve was made with C8 and T1.
The main component was C8 as the 964±430 nerve fiber. The upper subscapular nerve was derived from C5 and C6. The nerve fiber was 1,179±92 in C5, mainly participated. The Lower subscapular nerve was constituted of C5, C6 and C7. C6 was the main component and contributing nerve fiber was 1,070±390 in C6, principal component.
The thoracodorsal nerve was formed by C6, C7 and C8. The chief component was C7, contributed of 2,335±324. The nerves, which are came out from the distal portion of the cord, musculocutaneous nerve was derived from the C5, C6 and C7. The C6 was principal component, and was joined with 4,009±1,883. The median nerve was contributed from C5 to T1. The chief component was C7 added with 9,651±2,663. The ulnar nerve was composed of C7, C8 and T1. The C8 was the main component comprised of 10,075±1,473. The medial brachial and antebrachial cutaneous nerves was constituted of C8 and T1. In the both nerves, the main component was T1 participated with 1,752±390, 3,080±1,140 respectively. The radial nerve was composed of C5 to T1.
The C7 was principal component added with 7,958±2,333. The axillary nerve was made up C5 and C6. In the nerve, the both spinal segments were similarly participated to the nerve.
This results could be applied for the injuries and neurotization procedure of the terminal nerves of the brachial plexus.
