Question

3. Compare and contrast the structure and function of the somatic nervous system (SNS) and the autonomic nervous system (ANS) by addressing the following (Hint: Try a table. There is a similar one in your textbook but this is also covered in the lecture slides): a) Differences in the location (organ or organ region) of the receptors of the SENSORY neurons b) Differences in effectors that the motor neurons innervate c) Presence or absence of ganglia associated with motor neurons d) Composition of neurons in the motor pathways (number & name of type of neurons) e) Functional difference between the two (phrase describing the purpose of each)

Explanation / Answer

Somatic nervous system Autonomic nervous system Present in voluntary skeletal muscles Present in involuntary smooth muscles like intestinal and respiratory tracts The integrating center is present in spinal cord and motor cortex The integrating center is present in hypothalamus No ganglia in their motor nerve contains ganglia in their motor root There are two neurons in SNS pathway There are three neurons in ANS pathway Controls voluntary movements like walking, running etc. Controls involuntary movements like heart rate, respiration etc.
