Which structures make up the Peripheral Nervous System?

Explanation:
The Peripheral Nervous System consists of all neural elements outside the brain and spinal cord. This includes the peripheral nerves (spinal and cranial nerves) and their associated ganglia, which carry sensory information to the CNS and motor commands away from it. Since the brain and spinal cord form the Central Nervous System, they are not part of the PNS. Cerebrospinal fluid is a protective fluid around CNS tissues, not a nervous structure, so it isn’t part of the PNS either. Therefore, the structures that make up the Peripheral Nervous System are the nerves outside the CNS.
