Axon trajectory is influenced by the position of the cell body. In rax-3(bx138), axons of neurons with cell bodies at more anterior positions (R1B-3B) send their axons anteriorly (arrowhead), sometimes turning abnormally (e.g., in the animal shown there is a turn to the dorsal side). The cell body of R4B is located at the normal position of R1B (compare to wild type in bottom image) and its axon follows the expected pathway of the R1B axon in the wild type (arrow).
