How do our sensory organs work automatically without our conscious effort?

Question

I wonder how our different sensory organs (e.g., eyes, nose, ears, etc.) work automatically without our conscious efforts or without our command. We don't have to tell our eyes how to see, our ears how to hear, etc. How does this work?

Answer 1

The examples you gave are based on our cranial nerves which work the peripheral and central nervous systems working through the somatic or sensory division of these systems.
