Which dermatome is associated with sensation in the anterior lower leg?

Dermatome S1
Dermatome L2
Dermatome L5
Dermatome T10

The correct answer is: Dermatome L5

The sensation in the anterior lower leg is primarily associated with the L5 dermatome. The L5 dermatome encompasses the area from the front of the knee down to the top of the foot, specifically affecting the skin over the dorsum (top) of the foot and parts of the anterior (front) aspect of the lower leg. This region includes the sensation provided by the deep peroneal nerve, which is a branch of the common peroneal nerve and responsible for sensory innervation in this region. The other options relate to different parts of the lower limb or the body. For example, dermatome S1 generally corresponds to areas on the posterior aspect of the leg and the lateral side of the foot, while dermatome L2 covers the upper thigh and the groin region. Dermatome T10 is associated with the umbilical area, making it unrelated to the lower leg. Therefore, L5 is the correct dermatome for the anterior lower leg sensation.
