The nervous system of a roundworm is very simple. Ventral and dorsal nerve cords run through the roundworm's entire body. These cords come from the nervous tissue ring around its pharynx.
The nervous system of gastropods includes the peripheral and central nervous system and this central nervous system consists of ganglia connected by nerve cells. some of gastropods possesses simple and some complex nervous system. EX : 1) snail : Complex nervous system 2) chitons : simple nervous system
Yes, turtles have a nervous system. They have a brain that helps them process information and react to their environment. Their nervous system allows them to move, sense their surroundings, and perform various behaviors.
The control center of the body is the brain. The nervous system (commands the body) and endocrine system (secretes hormones) control body functions. The autonomic nervous system, the parasympathetic nervous system manage body functions without needing signals from the brain.
Yes, a puppy with roundworm is an example of parasitism because the roundworm is benefiting at the expense of the puppy by living in its intestines and deriving nutrients from it, causing harm to the puppy in the process.
Yes, leeches have a nervous system, although it is less complex compared to higher organisms. They have a simple nerve structure that allows them to detect changes in their environment and respond to stimuli like movement or the presence of food.
A roundworm has an open nervous system.

A closed circulatory system
The nervous system The central nervous system
No. Nervous System is comprised of the Central Nervous System (CNS) and the Peripheral Nervous System (PNS) The PNS is comprised of the Somatic Nervous System and the Autonomic Nervous System The Autonomic Nervous System is comprised of the Sympathetic Nervous System, the Parasympathetic Nervous System and the Enteric Nervous System
The Sympathetic Nervous System and the Parasympathetic Nervous System
The peripheral nervous system is the portion of the nervous system away from the central nervous system. It consists of nerves that connect the central nervous system to the rest of the body, including sensory and motor neurons. The peripheral nervous system is responsible for transmitting information to and from the central nervous system.
the peripheral nervous system
The somatic nervous system is a component of the peripheral nervous system. This system is responsible for voluntary movements and sensory information.
The autonomic nervous system is a division of the central nervous system.
The nervous system takes in sensory information from the peripheral nervous system. This information is then directed to the central nervous system which then responds with a motor reaction that travels back to the peripheral nervous system.
They are controlled by the autonomous nervous system.== ==
