Roundworm nervous system
Roundworms live in salt water, fresh water and the soil. Round worms get their name from their round cross section and long thread like bodies. A roundworm has two nerve cords that transmit impulses in the roundworm. Roundworms also have dorsal and ventral nerve cords. They also have a set of lateral nerve cords running across the body. Roundworms have a nervous ring around the pharynx and this ring that is connected to the dorsal and the nerve cord. All of these features make up the round worm's nervous system and allow it to move and function.
FUN FACTS- Males are usually smaller than the females. The females can deposit over 100,000 eggs per day.
