Question

Quizplus · Accepted Answer

Cephalization refers to the evolutionary trend of concentrating nervous tissue, sensory structures, and brain structures towards one end of the body. This is most commonly seen in animals with active movement and bilateral symmetry, where a concentrated nervous system can better coordinate movement and response to the environment. Concentration of these structures at the anterior (or front) end of the organism allows for quicker and more efficient sensing and response to stimuli in the environment.
