The Sea Snail - Flat periwinkle
Sea Snails has a relatively simple and easy nervous system, compared to other organisms. The Sea Snail typically does not have a brain, and instead they have clusters of nerves (ganglia) which function the same as the brain. The most productive and important ganglia is the cerebral one that is located in the head of the sea snails. The ganglia are evenly spread throughout the snail's body, and are most likely to be working in pairs. Sea Snails have body cells known as "perikarya" which carry out multiple functions. Some functions are relaying senses from parts of the nervous system, helping the snail move (motor neurons), and processing sensory information. Their nervous system is sometimes referred to being similar to Annelids.
