Question
Explain the role of the effector in a reflex arc and provide an example.
Answer
The effector in a reflex arc is responsible for carrying out the response to a stimulus. For example, in a knee-jerk reflex, the effector is the quadriceps muscle, which contracts to produce the knee jerk when the patellar tendon is tapped.
Explanation
This answer is effective as it defines the role of the effector and provides a specific example, demonstrating the student's ability to apply knowledge to a real-life scenario. The question assesses the student's understanding of the reflex arc and the function of effectors.
Common mistake
Misunderstanding the Reflex Arc Sequence
Students often confuse the order of components in a reflex arc, mistakenly placing the motor neurone before the relay neurone.
To fix this, students should memorize the correct sequence of the reflex arc: stimulus, receptor, sensory neurone, relay neurone, motor neurone, and effector. Visual aids or diagrams can help reinforce this order.
