| 11. | The Polystilifera are armed with a pad, or shield, bearing numerous small stylets.
|
| 12. | The stylets and the feeding tube form the modified mandibles, maxilla, and hypopharynx.
|
| 13. | The stylet is pointed and the lumen opening has a small protuberance on the ventral side.
|
| 14. | Male ring nematodes tend to be much thinner than females, and they lack a stylet.
|
| 15. | There are toothed stylets on the mandibles able to cut into and abrade tissues of their prey.
|
| 16. | As it is in the class Anopla, their proboscis is not armed with a barbed stylet.
|
| 17. | The maxillae form needle-like structures, called stylets, which are enclosed by the labium.
|
| 18. | The juveniles have an average stylet length of 20 ?m and have a thin finely pointed tail.
|
| 19. | This method involves removing the stylet of the spinal needle once the needle has advanced through the dermis.
|
| 20. | Once all of the CSF is collected, the stylet is then reinserted before removal of the needle.
