Fig. 3. Camera lucida drawings of motor nerve innervation of the flexor and extensor tibiae muscles in the cricket metathoracic leg, viewed posteriorly (A) and ventrally (B). The main flexor muscle (orange) is divided into the proximal-, middle- and distal regions, which are locally innervated by the proximal flexor nerve, the middle flexor nerve and the distal flexor nerve, respectively. A pair of muscle bundles of the accessory flexor muscle (red) are innervated by the anterior and posterior branches of the accessory flexor nerve diverging from the main leg nerve (N5B2).
