The human nervous system
Question
- A. To carry impulses from the CNS to effectors
- B. To detect stimuli and carry impulses to the CNS
- C. To connect the brain and spinal cord
- D. To produce hormones
Answer
The correct option is To detect stimuli and carry impulses to the CNS. This answer is correct because it matches the approved learning objective to explain how the nervous system enables rapid communication compared with hormonal coordination in the subtopic Structure and function.
Explanation
The correct option is To detect stimuli and carry impulses to the CNS. To detect stimuli and carry impulses to the CNS is correct because it directly supports the approved learning objective to explain how the nervous system enables rapid communication compared with hormonal coordination. This belongs to the subtopic Structure and function within The human nervous system, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Structure and function.
Common mistake
Misunderstanding Communication Speed
Students often confuse the speed of communication in the nervous system with that of hormonal coordination, thinking they are similar.
Emphasize that the nervous system communicates rapidly through electrical impulses, while hormonal coordination is slower due to the reliance on the bloodstream.
