STUDY OF THE MEDIAN AND ULNAR NERVOUS BRANKS TO KAPLAN'S LINE.

Objective: This study aims to present lines A1 and A2 in association with Kaplan's cardinal line (LCK), and relate them to the thenar motor branch of the median nerve (RMTNM) and to the deep branch of the ulnar nerve (RPNU).

Methods: Ten hands of five adult cadavers were dissected.

Results: The RMTNM origin was positioned proximal to the LCK in all limbs.
