Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The formation of a nerve mass in the anterior end of the body is called ____
A
cephalization
B
anteriorization
C
sensory development
D
regerneration
Explanation: 

Detailed explanation-1: -Cephalization: Coricentration of nerve (Brain) and sensory cells at the anterior end of the body is called as Cephalization. As a result of cephalization, these animals can sense the new environment and move efficient than the other animals in seaking food, locating mates and in avoiding of escaping from predators.

Detailed explanation-2: -cephalization, the differentiation of the anterior (front) end of an organism into a definite head.

Detailed explanation-3: -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-4: -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-5: -The development of a complex brain is one of the advantages of cephalization, which allows organisms to survive in better and smarter ways. The brain organizes and controls sensory information by acting as a control center. Over time, the complex neural system evolved, and intelligence developed.
