What functions do different parts of the analyzer perform in the human body?

The analyzer is a system of neurons that perceive stimuli, conduct nerve impulses and provide information processing. Each analyzer consists of three parts.
1) The peripheral section is the receptors. The receptor perceives irritation and converts it into a nerve impulse, excites a sensitive neuron.
2) The conduction section is the nerves and pathways. They conduct excitation to the central nervous system.
3) Central, located in the cerebral cortex – the final analysis of information, the emergence of an image.
