During dissection of the right forearm of a 27-year-old female cadaver, variations in the form and insertion of the palmaris longus muscle were observed. The tendon of the palmaris longus muscle, which demonstrated a centrally placed belly, split into two tendons: one inserted into the palmar aponeurosis and the other into the proximal part of the flexor retinaculum. Additionally, we found an accessory muscle extending between the flexor retinaculum and the tendon of the abductor digiti minimi muscle. This accessory muscle was located deep to the ulnar artery but superficial to the superficial and deep branches of the ulnar nerve at the wrist. Finally, an aberrant branch of the ulnar nerve was identified in the forearm; it traveled distally alongside the ulnar artery and in the palm demonstrated communications with common palmar digital nerves from the ulnar and the median nerves. No variations were observed in the contralateral upper limb.
在解剖一名27岁女性尸体的右前臂时,观察到掌长肌的形态和附着点存在变异。掌长肌肌腱肌腹位于中央,分成两条肌腱:一条附着于掌腱膜,另一条附着于屈肌支持带近端。此外,我们发现一条副肌在屈肌支持带和小指展肌肌腱之间延伸。这条副肌位于尺动脉深面,但在腕部位于尺神经浅支和深支浅面。最后,在前臂发现一条尺神经异常分支;它沿尺动脉向远端走行,在手掌与来自尺神经和正中神经的指掌侧总神经有交通。对侧上肢未观察到变异。
