The nerve cord in an earthworm performs the same task as the nervous system of any animal. The function of the nervous system is to bring sensory information to the brain, where it is processed. Then, the brain sends signals to the body via the nervous system and those signals cause the animal to move.t's function is simple; â¦ it's the nerves in the worm! If dissected, the nerve cord looks like a thin white line on the ventral (belly) side on the inside of the skin.
Earthworms are hermaphrodites where each earthworm contains both male and female sex organs. The male and female sex organs can produce sperm and egg respectively in each earthworm. Although earthworms are hermaphrodites, most need a mate to reproduce. During mating, two worms line up inverted from each other so sperm can be exchanged. The earthworms each have two male openings and two sperm receptacles, which take in the sperm from another mate. The earthworms have a pair of ovaries that produce eggs. The clitellum will form a slime tube around it, which will fill with an albuminous fluid. The earthworm will move forward out of the slime tube. As the earthworm passes through the slime tube, the tube will pass over the female pore picking up eggs.
