Brain stem
The brain sends messages to the nerves:)
Voluntary actions are those that are consciously controlled and performed with intention, such as deciding to walk or speak. In contrast, involuntary actions occur automatically and often without conscious thought, like reflexes or the beating of the heart. While voluntary actions involve active decision-making, involuntary actions are typically governed by the autonomic nervous system and are crucial for survival.
Brain Stem is what I found but we may not have the same key terms paper.
Involuntary actions are movements or processes that occur automatically without conscious control, such as heartbeat or digestion. Reflex actions are quick, automatic responses to a stimulus that involve a specific neural pathway, like withdrawing your hand from a hot stove.
