Answer Details

The nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord. The PNS consists of all the nerves and neurones that connect the CNS to the rest of the body.

The components of the peripheral nervous system include:

• Sensory neurones (afferent neurones), which carry impulses from receptors (such as those in the skin, eyes, and ears) to the CNS.
• Motor neurones (efferent neurones), which carry impulses from the CNS to effectors (muscles and glands).
• Cranial nerves (12 pairs emerging directly from the brain) and spinal nerves (31 pairs emerging from the spinal cord).
• Ganglia (clusters of nerve cell bodies located outside the CNS).

The cerebellum is a part of the brain responsible for coordinating movement and balance, so it belongs to the CNS. The brain itself is the main organ of the CNS, and the spinal cord is the other major CNS structure. None of these three are components of the PNS.

Of the options given, sensory neurones are a component of the peripheral nervous system, as they form the pathways that carry information from the body's receptors to the central nervous system.
