NERVOUS SYSTEM
- Central nervous system
- Nerve ring
- Longitudinal nerves
- Commissures
- Cephalids - {anterior, posterior}
- Hemizonid
- Hemizonion
- Caudalid
- Peripheral nervous system
- Sensory organs
- Amphids ("Also in" Neck)
- Amphid opening = Amphidial pore = Amphidial aperture
- Sensillae = (Papillae)
- Labial sensillae ("Also in" Head) = (Labial papillae)
- Outer sensillae - {lateral, subdorsal, subventral}
- Inner sensillae - {lateral, subdorsal, subventral}
- Cephalic sensillae ("Also in" Head) = Setae = (Cephalic
papillae)
- Caudal sensillae ("Also in" Tail)= Caudal papillae = Submedian
papillae
- Deirids ("Also in" Neck)
- Phasmids - {anterior, posterior}
- Phasmidial ribs ("Also in" Caudal alae)
- Phasmid opening ("Also in" Lateral fields)
- Ampulla = Lens
- Phasmid-like structures ("Also in" Lateral fields)
