  8. Steps in mating Jarrells..Emmons 2012

  9. Step #1: Males chemotax toward hermaphrodite-conditioned media White..Jorgensen 2007

  10. AWC, AWA & CEM are involved in male chemotaxis to hermaphrodite odors White..Jorgensen 2007

  11. Hermaphrodites with a masculine nervous system are attracted to hermaphrodite odors White..Jorgensen 2007

  12. Step #2: Structures required for contact response Liu & Sternberg 1995

  13. Steps #2 and #4: Structures required for contact response and turning Liu & Sternberg 1995

  14. wild-type: tight turn Last 3 rays ablated: late turn Dopaminergic rays (5A, 7A, 9A) ablated: wide, sloppy turn Liu & Sternberg 1995

  15. Exogenous serotonin induces ventral coiling, perhaps by directly contracting muscle mM Loer & Kenyon 1993

  16. Serotonergic neurons in the male tail Loer & Kenyon 1993

  17. Step #5: Locate the vulva Liu & Sternberg 1995

  18. Steps #6 and #7: Insert spicule into vulva and ejaculate Liu & Sternberg 1995

  19. Muscle structure for spicule protraction Garcia & Sternberg 2001

  20. Steps for spicule insertion Garcia & Sternberg 2001
