Simplified diagram of the innervation of muscles and prominent sense organs of locust legs. Please note that N5B2 in the proximal tibia splits into two major branches (N5B2ant, N5B2post) that proceed toward the tarsus. Triangles mark the sites where nerves were filled. Projections into the brain were only observed after filling the main nerve 5B2 in the femur (site 1) or its anterior tibial branch (sites 2 and 3). The numerous tegumentary branches of the major leg nerves (N5B1 and N5B2) that innervate the hair sensilla on the cuticle are not shown.
