Table 1 Classification of the sensory and motor ciliated cell types of Paralvinella hessleri

From: Sensing deep extreme environments: the receptor cell types, brain centers, and multi-layer neural packaging of hydrothermal vent endemic worms

Cell types Body localities Projections in CNS Specific characters ciliary length/width Possible homologies
Sensilla type branchial crown anterior VNC chemical sensory cells penetrative sensory cells
  whole bodies VNC, each segment chemical sensory cells 1-12/0.3μm  
Line type dorsal prostomium anterior VNC forming lines on the dorsal head 4-13/0.2μm neck ciliary bands?
Tuft type whole prostomium brain, MB round and short cilia 1-3/0.2μm penetrative sensory cells
Bud type ventral area of notopods VNC roughly lined with pods 1-21/0.1-0.2μm(sharp) olfactory organ-like
Patch type lateral branch and whole bodies - typical motor cilia 1-12/0.2μm motor ciliary cells
Ventral patch type ventral abdomen - ventrally localized 1-11/0.2μm sensory receptor cells?
lateral organs
  1. Possible homologies are based on Purschke [38]. MB, Mushroom body; VNC, Ventral nerve cord.
