Nervous System
Before you respond to the following question, make sure you have completed the readings,
self-assessments, labs, and other activities for the module. To do well on the question, you
will need to use the proper terminology and cover each point in the question in-depth. Be
sure to define important terms and provide real world examples of how the concept relates
to living organisms.
2007 Question #2:
Cephalization and the development of the brain were important steps in animal evolution.
1. Discuss the evolutionary origin and adaptive significance of cephalization in animal
phyla.
2. Describe the development of the nervous system in the vertebrate embryo.
3. At the sound of shattering glass, people quickly turn their heads. Discuss how the
human nervous system functions to produce this type of response to an external
stimulus.
Read the question above and create a document in which you develop responses to the
question. Evaluate your essay by using the rubric provided. After you review and make the
necessary corrections to your essay, submit your assignment to the Nervous System Free
