Annelids are segmented whereas roundworms are not. Annelids have a true coelom while roundworms have a pseudocoelom. Annelids have a more complex nervous system than roundworms. Annelids have a more complex circulatory system than roundworms.
The autonomic nervous system consists of two sub divisions: The sympathetic nervous system and the parasympathetic nervous system.
The central nervous system consists of the brain and spinal cord.
the central nervous system which consists of the brain and spinal cord. the peripheral nervous system which consists of nerves and ganglia (collection of nerve cell bodies outside the central nervous system). AND -peripheral. -central.
The nervous system consists of the brain which brings throughout your body Theirs two parts of the nervous system, the cetral nervous system, and the peripheral nervous system. The central nervous system contains the brain, spinal cord, and retina. The peripheral nervous system consists of sensory neurons, clusters of neurons called ganglia, and nerves connecting them to each other and to the central nervous system.

The central nervous system consists of the brain and the spinal cord
The autonomic nervous system consists of the sympathetic nervous system, which prepares the body for fight or flight responses, and the parasympathetic nervous system, which promotes rest and digestion.
Yes, annelids have a relatively complex organ system compared to other invertebrates. They have a well-developed digestive system, a closed circulatory system, a nervous system with a ventral nerve cord, and excretory organs called metanephridia. Overall, annelids exhibit a higher level of organization than simpler invertebrates.

The central nervous system consists of the brain and spinal cord.
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.
