Yes they do, invertebrates have small nervous systems, which consist of many small brains. Because of the anatomy of their nervous systems and the lack of neurons, they are thought to have limited cognitive capacity, and this means that they are likely to not be capable of emotions like we feel. This is why scientists are unsure whether or not or to what degree they feel pain.
Amphibians have a relatively simple nervous system compared to mammals and birds. They possess a central nervous system composed of a brain and spinal cord, as well as peripheral nerves that transmit information throughout the body. Their nervous system allows for basic behaviors such as movement, feeding, and responses to environmental stimuli.
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 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.== ==
