In Platyhelminthes, or flatworms, cephalization primarily affects nervous tissue. This process involves the concentration of nerve cells and sensory organs in the anterior region of the organism, leading to the formation of a head-like structure. As a result, the nervous system becomes more complex, allowing for improved sensory perception and response to environmental stimuli. Additionally, this development is accompanied by changes in other tissues to support the more centralized nervous system.
