Answer:
True
Explanation:
The sympathetic autonomic nervous system activates the body for hormonal or neuronal responses also known as fight- or - flight response, For example during an fire emergency and there is a need to run. The response occurs primarily by via impulses transmitted through the sympathetic nervous system, and also secondarily through catecholamines secreted from the adrenal medulla.
