EspañolPARAPODIUM
(Redirected from Parapodia)
'Parapodia' (Gr. ''para'', beyond or beside + ''podia'', feet), singular 'parapodium', are paired un-jointed lateral outgrowths. They are characteristic of Polychaeta.
Parapodia are either uniramous or biramous. In the latter case, the dorsal lobes or branches are called 'notopodia' and the ventral branches 'neuropodia'.
Both neuropodia and notopodia can bear cirri (called respectively 'neurocirri' and 'notocirri') and setae (called respectively 'neurosetae' and 'notosetae'). The cirri between the two branches are called 'interramal cirri'.
The fleshy protrusions on the sides of some snails are also called parapodia (especially characteristic of sea butterflies).
