somatic

Explanation:

All the voluntary actions of a person are controlled via the somatic nervous system and the skeletal muscles.

It consists of two types of nerves:

Afferent nerves or sensory nerves

Efferent nerves or motor nerves

Sensory signals to the Central Nervous System (CNS) are sent through the afferent nerves.

Commands from the CNS are sent via the efferent nerves to the rest of the body.

Hence, Julie would use the somatic nervous system.
