Answer 1

Answer:

Streptoneury

Streptoneury or chiastoneury is a plesiomorphic condition present in all gastropods which is a result of an evolutionary event called torsion in which the intestines, heart, nephridia, gills, and nerve cords "twist" causing some organs to migrate from the animal's left to its right in order to accommodate the ...

Answer 2

Chiastoneury in Pila:

• In all the gastropods, a plesiomorphic type condition causes the process of torsion.
• This evolutionary method is the process of twisting certain parts of the gastropods like gills, intestines, heart, and nerve cords and relocating some of their organs to the right side.
• This condition that is responsible for the torsion is known as Chiastoneury or even Streptoneury.
• In Pila species, this chiastoneury is responsible for twisting the infra-intestinal part of the ganglion to that of the pleuro-pedal mass of ganglion present on the right side.
• The twisting of the ganglia makes the chiastoneury in Pila somewhat invisible or unclear.
• This results in the diffusion of the chiastoneury in Pila.
