Answer 1

Humans have an **autonomic nervous system** that controls bodily functions and muscles automatically. They also have a **somatic nervous system** that allows conscious control of muscles.

Some muscles are controlled by both – we breathe automatically, but we can also take a deep breath, exhale, or hold our breath. We blink automatically, but can also blink/wink when we wish. Eye focus muscles is also one of those that mostly work automatically, but we also have somatic control over.
