D___We feel something by our CNS and PNS as well.

3 (individual work). Answer the questions using text below.

1. What are functions of somatic nervous system?
2. What causes small intestine to move?

4 (team work). Discuss your answers.

The nervous system can also be divided on the basis of how it controls the body. The somatic nervous system (SNS) is responsible for functions that result in moving skeletal muscles. Any sensory or integrative functions that result in the movement of skeletal muscle would be considered somatic. The autonomic nervous system (ANS) is responsible for functions that affect cardiac or smooth muscle tissue, or that cause glands to produce their secretions. Autonomic functions are distributed between central and peripheral regions of the nervous system. The sensations that lead to autonomic functions can be the same sensations that are part of initiating somatic responses. Somatic and autonomic integrative functions may overlap as well!

5 (individual work). Write a story using information from the picture “How reflex works”.
