Which dermatome is on the pinky toe?

Explanation:
Dermatomes map skin areas to specific spinal nerve roots. The pinky toe sits in the S1 dermatome, which covers the lateral side of the foot and the little toe. That’s why the pinky toe corresponds to S1. Other mappings place different regions with other roots: C6 relates to the thumb side of the hand, T1 to the medial forearm/arm, and L4 to the medial leg and big toe area. So the pinky toe being S1 fits the typical dermatomal distribution.
