What is the localization of a brain and specialized sensory organs at the anterior end of an animal?
In zoology, cephalization is the evolutionary trend toward concentrating nervous tissue, the mouth, and sense organs toward the front end of an animal. Fully cephalized organisms have a head and brain, while less cephalized animals display one or more regions of nervous tissue.
How do vertebrates respond to stimuli?
In general, invertebrates, like vertebrates, respond to such stimuli by withdrawing or escaping so as to reduce the likelihood that they will be damaged by the noxious conditions.
