5 True/False Questions

1. Meninges → carry impulses TO cell body

   True        False

2. NEURON → basic unit of structure and function of the NS

   True        False

3. Reflex → Receptor - to spinal cord interneuron - to motor neuron of affected area

   True        False

4. Reflexes do NOT involve → Receptor - to spinal cord interneuron - to motor neuron of affected area

   True        False

5. Spinal Cord → Link between brain and Peripheral NS
   Responsible for reflexes

   True        False
