Summary

Terminologia Anatomica contemplates the existence of common palmar digital nerves from the superficial branch of the ulnar nerve and common plantar digital nerves from the superficial branch of the lateral plantar nerve. According to most classical texts and anatomical studies of the regions palmar and plantar, there would only be common palmar digital nerve (IV) originated from the superficial branch of the ulnar nerve and common plantar digital nerve (IV) arising from the superficial branch of lateral plantar nerve. We conducted an anatomical review of the cutaneous innervation of the palm observing the behavior of the median and ulnar nerves, and the foot through the medial and lateral plantar nerves. In this study we discuss the related literature and conclude that Terminologia Anatomica must be corrected in the A14.2.03.046 term (Nn. common palmar digital) and in A14.2.07.071 term (Nn. common plantar digital ), which should be called: common palmar digital nerve and common plantar digital nerve, corresponding to both the IV common palmar digital nerve and IV common plantar digital nerve, respectively.

KEYWORDS: Ulnar nerve; Palmar digital nerves; Lateral plantar nerve; Plantar digital nerves.
