Üst ekstremitede arteriyel ve muskuler varyasyonlar

Rutin öğrenci diseksiyonlarımızda, bir erkek kadavranın sol üst ekstremitesinde arteriyel ve müsküler varyasyonlar gözlendi. Arteria radialis'in yüzeyelde olduğu, arcus palmaris superficialis'in sadece a. ulnaris tarafından oluşturulduğu, m. palmaris longus'un yoklu- ğu ve m. extensor digiti miniminin üç adet tendona sahip olduğu tespit edildi. Varyasyonlar embriyolojik kökenli olduğundan aynı bölgede farklı yapılarda normalin dışında görünümler birliktelik gösterebilir. Bu yüzden anatomik ve klinik çalışmalarda bir varyas- yon tespit edildiğinde aynı bölgede diğer yapılarda da farklılık gözlenebileceği akılda tutulmalıdır.

Arterial and muscular variations in the upper limb

During our routine dissection studies we observed arterial and muscular variations in the left upper limb of an adult male cadaver. In this case we observed the superficial radial artery, the superficial palmar arch was formed by the ulnar artery along, the palmaris longus muscle was absent and the extensor digiti minimi muscle had got three tendons. Variations in the same area may be observed in different structures as the variations are embryological origin. For this reason, when a variation is detected in anatomic and clinical studies, it should be kept in mind that differences may be observed in the other structures in the same area.
