The peripheral and central nervous organization of the locust coxo-trochanteral joint.
The micromorphology of the locust cox0-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.
