초록
얕은손가락굽힘근은 아래팔 앞칸에 있는 근육중 중간층에 위치한 근육으로 갈래의 수와 이는곳, 근육가지 (muscle slip)의 분포와 연결, 그리고 손가락에 닿는곳까지 다양한 변이가 보고되었다. 본 증례에서는 일개 의과대학 해부학실습 중 시신에서 관찰된 얕은손가락굽힘근의 복합적 변이를 보고하고자 한다. 얕은손가락굽힘근 힘줄이 얕 은층과 깊은층으로 분리된 변이, 근육가지의 구조적 변이와 이와 연계된 힘줄의 변이 및 긴엄지굽힘근으로 향하는 Gantzer근육의 발견 등 여러가지 복합적인 변이를 확인하였다. 얕은손가락굽힘근에서의 이러한 복합적인 변이는 매 우 드문 경우로서, 본 증례 보고에서는 변이와 관련된 비교해부학적, 발생학적 의의를 고찰하였다.
Abstract
The flexor digitorum superficialis (FDS) muscle is located in the intermediate layer of the muscles in the anterior compartment of the forearm. Variable but individual variations have been reported in the FDS regarding the number of head and the origin, distribution and interconnections of muscle slip and insertion to finger. In this case, we report a concomitant complex variation in FDS which was observed in a cadaver during a routine dissection classes for the undergraduate medical students. It includes the variation which is the separation of the tendon of FDS into the superficial and deep layers, the structural variations in muscle slips and associated tendon variations, the finding of Gantzer’ muscle leading to flexor pollicis longus muscle. These complex variations in FDS are very rare case and this report summarizes the related phylogenetic and embryological significance.
