Question

a researcher is trying to isolate the neural pathways that control movement in the lower legs. to do this, he conducts a clinical experiment in which he electrically stimulates different locations in the spinal cord of his subjects and observes their responses. when they experience movement in their lower legs, he identifies the exact location of the stimulation to see if it is reproducible in later research. because he is manipulating a variable, his experiment can still show a clear cause - and - effect relationship between the stimulation and the movement. elimination tool select one answer a sympathetic nervous system b parasympathetic nervous system c central nervous system d peripheral nervous system

Explanation:

The spinal cord is part of the central nervous system. The sympathetic and parasympathetic nervous systems are part of[SSE Completed, Client Connection Error][SSE Completed, Client Connection Error][SSE Completed, Client Connection Error][LLM SSE On Failure]

Answer:

The spinal cord is part of the central nervous system. The sympathetic and parasympathetic nervous systems are part of[SSE Completed, Client Connection Error][SSE Completed, Client Connection Error][SSE Completed, Client Connection Error][LLM SSE On Failure]
