The relationship between vertebral body and the motor segment-innervated APB and ADM.

Tuzuki et al. reported the relationship between the vertebral body and motor segment in 14 cadaver specimens.7 The motor segment-innervated APB was consistent with the presence of the T1 motor segment cord at the C7 vertebral body. The motor segment-innervated APB was more caudal than the motor segment-innervated ADM.
