Question

You pull out of the school parking lot and almost enter the road in front of an oncoming truck. For the next several minutes, you experience an increase in your breathing rate, heart rate, blood pressure, and vision sensitivity. What aspect of the sympathetic division is this attributed to?
A- Mass activation
B- Stimulation of the reticular activation system
C- Numerous axons cause an effect in many effector organs

Answer 1

Answer:

The correct option is A: Mass activation

Explanation:

The flight-or-fight response that gets activated in these type of situations is attributed to the sympathetic nervous system. It causes the release of adrenaline into the bloodstream and several other changes occur, as mentioned in the question statement, these changes prepare the body to react promptly to the situation at hand.

Hope that answers the question, have a great day!

Answer 2

Answer:

The answer is C.

Explanation:

The sympathetic nervous system (SNS). it is predominant in dangerous situations.

It provokes the appropriate actions for rapid response such as: increased heart rate, dilated bronchi to promote the entry and exit of gases, increased sweating, decreased intestinal peristalsis to decrease the energy invested in digestion, vasoconstriction of the arteries, dilation of the pupils so that more light enters, etc.

For this reason axons quickly send a response to all these organs through the sympathetic nervous system.
