Detailed explanation-1: -Cephalization is the concentration of sense organs, nervous control, and so on at the anterior end of the body, resulting in the formation of a head and brain, both during evolution and during embryonic development.
Detailed explanation-2: -Cephalization is an evolutionary trend in which, over many generations, the mouth, sense organs, and nerve ganglia become concentrated at the front end of an animal, producing a head region. This is associated with movement and bilateral symmetry, such that the animal has a definite head end.
Detailed explanation-3: -Cephalization is the phenomenon in which an organism will have their sensory organs concentrated at one end of the body. This process occurs over many generations. Cephalzation is present in all vertebrates and in some invertebrates such as flatworms.
Detailed explanation-4: -Cephalization means that the concentration of sensory organs and nerve cells are located in the anterior part of the body.
Detailed explanation-5: -Besides the symmetry of their bodies, bilateral animals are characterized by cephalization: they have a concentration of sensory organs and nerve tissue, often a brain, at their anterior, or front, end.
