Which dermatome is associated with the obturator nerve cutaneous zone?

The obturator nerve is primarily responsible for the innervation of the medial aspect of the thigh and is closely associated with the L2 and L3 dermatomes. However, its cutaneous zone, particularly where sensory innervation is felt on the skin, is most prominently associated with the L2 dermatome.

In the context of dermatomes, L2 generally corresponds to the upper thigh region, where the obturator nerve provides sensation. This area falls within the distribution of the L2 dermatome, making it the correct answer. Understanding the association of nerves with specific dermatomes helps in identifying areas of sensation and potential injuries or issues related to nerve damage.
