The major dermatome for the great toe is which spinal level?

Explanation:
Dermatomes map each spinal nerve root to a skin region. The L4 dermatome runs along the medial aspect of the leg into the foot and includes the great toe (hallux). That makes sensation in the big toe a classic indicator of L4 distribution. Other roots occupy different regions: L3 is more proximal on the thigh/knee area, L5 covers much of the dorsum of the foot and some toes, and S1 tends to the lateral foot and sole. So the great toe falls primarily within the L4 territory, making L4 the best answer.
