The card says that sensory innervation is none. This is misleading though and could 100% drive someone to get the question wrong if they just assumed NONE (especially with peroneal nerve compression being an option choice on the question). The Sciatic nerve is a sensorimotor nerve (stated in Amboss). Though it does not provide direct sensory innervation, a lesion of the sciatic nerve would ultimately affect its branches (the tibial nerve and common peroneal nerve). Saying it has NO sensory information is misleading. A rephrase should be made to either "direct" sensory or to say provides sensory to the lower leg and foot through its division into the tibial and common peroneal nerve.
