It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions. The anterior horn cells, although technically part of the central nervous system (CNS), are sometimes discussed with the peripheral nervous system because they are part of the motor unit.
Just so, are the spinal nerves part of the CNS or PNS?
The peripheral nervous system or PNS contains the nerves, which leave the brain and the spinal cord and travel to certain areas of the body. The peripheral nervous system's main job is to send information gathered by the body's sensory receptors to the CNS as quickly as possible.
What are the differences between the CNS and PNS?
Together the spinal cord and the brain form the central nervous system (CNS). It is connected to the peripheral nervous system (PNS) which includes the nerves in our extremities. But, there are big differences between the two. And, there are more cell types in the nervous system than just neurons.
