Question

4.
When the doctor strikes Sofia’s knee with a tool, her leg automatically kicks into the air. What BEST explains this movement?


Sofia’s brain is responding to a stimulus.


Sofia has great reaction time.


Sofia has working reflexes.


Sofia’s body is demonstrating its power.

Answer 1

The best explanation for this movement is that Sofia has working reflexes. When the doctor strikes Sofia's knee with a tool, her leg automatically kicks into the air in a reflexive response. Reflexes are involuntary actions that occur in response to certain stimuli, bypassing conscious thought and involving a direct neural pathway from the sensory receptor (in this case, the knee) to the motor neuron (causing the leg to kick).
