Detailed explanation-1: -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-2: -Cephalization is an evolutionary trend to concentrate sensory and neural organs anteriorly in a head. In the field of the neurosciences, it may be defined as the progressive growth of the (cephalic) nervous system during the evolution of animal life.
Detailed explanation-3: -Cephalization is basically one type of evolutionary process by which the sensory organs are concentrated at an animal’s anterior portion (head). This leads to the development of the head. Therefore, the brain is developed within the head through the process of cephalization.
Detailed explanation-4: -cephalization, the differentiation of the anterior (front) end of an organism into a definite head.
Detailed explanation-5: -From generation to generation, an evolutionary trend is formed in which sense organs, mouth, and nerve ganglia in animals become concentrated at the front end of an animal that produces a head a region.
