<span>The Parasympathetic Nervous System (PNS) has a general function of controlling bodily functions such as homeostasis and the body's response during rest. </span> <span>The Sympathetic Nervous System (SNS) on the other hand refers to the body's response to perceived danger. </span> Each of these result in different bodily responses. In the case of the PNS these include: a decreased heart rate, bronchial tube constriction, relaxation of muscles and the constriction of th pupils. When it comes to the SNS, these responses include: increased cardiovascular contraction (leading to an increased heart rate), dilation of the bronchial tubes, contraction of muscles and dilation of the pupils/
<span>The central nervous system (CNS) and peripheral nervous system (PNS) work together in a multitude of ways. The (PNS) is ultimately the extension of the (CNS)</span>
