  3. UNIT3 Types of nervous systems Network of neurons • Found in cnidarians (polyps and jellyfish). • They do not have a central nervous system. They just have a network of interconnected neurons running along the walls of their bodies. Network ofneurons A network of neurons in a polyp Natural Science 2.

  4. UNIT3 Types of nervous systems Central nervous system • Found in most animals: • In a central nervous system, neurons are grouped together to form: • Nerve centres, which are normally found in the head. They process information: • Ganglia: in molluscs and arthropods • Brain and spinal cord: in vertebrates • Nerves, which connect the sense organs to the nerve centres and these centres to the effectors.
