Abstract
The micromorphology of the locust coxo–trochanteral joint was examined in cobalt‐stained material. Peripheral nervous system, musculature, and internal proprioceptors—two strand receptors and a muscle receptor organ—of the metathoracic coxa are compared with those of the pro‐ and mesothoracic legs. The number and position of trochanter levator and depressor motoneurons as well as the central projections of coxal sense organs are described. Evidence for a femoro–tibial strand receptor was obtained by tracing the path of a particular nerve branch.
