1. Doctors use a rubber mallet to test the function of your nervous system. They tap the tendon below your kneecap and your leg kicks out in response. This is a (blank) reflex.

2. The knee reflex also works without thinking because reflexes don't require the (blank) .

3. In a knee reflex, sensory impulses from the knee tendon are carried to the . In response, (blank) impulses are sent to the muscles of the knee so it kicks out.

4. A (blank) is the shortest nerve pathway between the spinal cord and a corresponding muscle or gland and usually includes only two or three neurons.

5.The five parts of a reflex arc are a receptor, a (blank) neuron, an (blank) , a (blank) neuron, and an effector.

6. A reflex arc starts with a (blank) at the receptor.

7.The impulse moves along a sensory neuron, through the (blank) root.

8. The impulse moves into your spinal cord where it passes to an (blank) .

9. The interneuron processes the signal and sends it through the (blank) root to a motor neuron.

10. The (blank) neuron passes the impulse to one of your muscles or glands to stimulate a response.
