What is an involuntary nerve?

An involuntary nerve refers to the components of the autonomic nervous system, which controls involuntary bodily functions such as heart rate, digestion, and respiratory rate. Unlike voluntary nerves that govern conscious movements, involuntary nerves operate automatically without conscious control, regulating essential processes that maintain homeostasis in the body. These nerves are divided into the sympathetic and parasympathetic systems, which work together to balance the body's responses to stress and relaxation.
