ANSWERS AND EXPLANATIONS

---

A) Lower motor neurons

This answer is incorrect.

The peripheral nervous can be defined as including the peripheral nerves (including roots, plexi, and nerves proper), the neurons that run within the peripheral nerves, the neuromuscular junctions, and the muscles. Cranial nerves III - XII are usually included in this definition. The brain, spinal cord, and cranial nerves I and II make up the central nervous system.  (See References)
