Question at position 10: Which part of the nervous system will be most active when Martin, a backpacker, acts quickly in response to a wild animal approaching him? central nervous systemparasympathetic nervous systemsympathetic nervous systemsomatic nervous system

Option 1: central nervous system. The CNS includes the brain and spinal cord and is responsible for processing information, but rapid, fight-or-flight reactions are typically coordinated through autonomic pathways that initiate quick bodily responses, which is not the same as the CNS being the most active in immediate action.

Option 2: parasympathetic nervous system. This branch promotes rest, digestion, and conservation of energy. It generally counteracts stress responses and slows down heart rate and arousal, which would be counterproductive in a sudden threat requiring fast action.

Option 3: sympathetic nervous system. This branch is part of the autonomic nervous system that mediates the fight-or-flight response. It increases heart rate, dilates airways, dilates pupils, redirects blood flow to muscles, and prepares the body for quick, muscular action, making it the most active during an urgent threat.

Option 4: somatic nervous system. The somatic system controls voluntary movements via skeletal muscles, but the question asks which part of the nervous system will be most active overall in rapidly responding to danger, which is driven by the autonomic arousal of the sympathetic system rather than conscious motor control alone.
