Paris has just found out that her company is downsizing their staff and that she is highly likely to lose her job at any moment.
Her heartbeat is increasing, she feels warm, and she has to take several deep breaths to try to calm down. The part of her body that is currently 'speeding her up' is called the ________ nervous system.
The sympathetic nervous system is also referred to as the fight, flight response. The sympathetic nervous system is a division of the autonomic nervous system and the other being the parasympathetic system. The autonomic nervous system regulates involuntary physiological processes.
The sympathetic nervous system is activated when there is intense physical activity, the sympathetic nervous system stimulate the body to respond in such a way that there is increased heartbeat, increased respiratory.
The sympathetic nervous system is one of the main components of the autonomic nervous system that controls involuntary movement functions such as heart rate, dilation of pupils etc. The sympathetic nervous system specifically controls such involuntary functions unconsciously when the body senses a threat or stressor. It is responsible for initiating the body’s “flight or fight response.
The threat of Paris losing her job is what her body senses as distress signal, which leads to the activation of the sympathetic nervous system by the hypothalamus. Hormones such as adrenaline is pumped into the bloodstream to elevate the body’s alertness and heart rate as a response to the distress signal.
One of the main premises in the study of the immunology of exercise is the possible role that exercise or physical activity may have in both prevention and cure of diseases; and, specifically, in the chronic and acute responses of the immune system to exercise.
