TheSce-elav+profile ofS. cephalopterahatchlings reveals that, within 24 h of post-embryonic development, the developing neural territories are not limited to the regions previously ascribed to the cerebral ganglion, the ventral nerve center (VNC), and the sensory organs, but also extend to prev...
Motoneurons in the L6 segment innervate several limb muscles (including the plantar foot muscles, gluteal muscles, hamstring muscles, and crural muscles) as well as the pelvic muscles. Some of the L6 motoneurons are sexually dimorphic, are more numerous in males and reside in two groups: the ...
