Yes, the sympathetic and parasympathetic nervous systems can be active simultaneously, a phenomenon known as autonomic co-activation. This occurs in certain situations where the body requires a balance of functions, such as during stress when the sympathetic system prepares the body for action, while the parasympathetic system may still manage functions like digestion. The two systems often work in opposition to regulate bodily responses, but their simultaneous activation can help fine-tune responses to complex situations.
The sympathetic and parasympathetic nervous systems are subdivisions of the autonomic nervous system.
The parasympathetic and sympathetic divisions of the autonomic nervous system or antagonistic. They have opposing effects.
The parasympathetic and sympathetic systems are branches of the autonomic nervous system.

The effects of the sympathetic nervous system are essential opposite those of the parasympathetic nervous system. The sympathetic nervous system accelerates functions such as heart rate and breathing and the parasympathetic slows these bodily processes down. The sympathetic also inhibits digestion, whereas the parasympathetic stimulates digestion. The sympathetic nervous system produces "fight-or-flight" reactions, while the parasympathetic functions under relaxed conditions.
The autonomic nervous system is divided into the sympathetic and parasympathetic systems.
parasympathetic and sympathetic nervous systems
Vasoconstriction is primarily controlled by the sympathetic nervous system.
The Sympathetic Nervous System and the Parasympathetic Nervous System
Sympathetic
The parasympathetic nervous system allows the act of micturition. The sympathetic nervous system inhibits it.
Bronchoconstriction is due to an activation of parasympathetic nervous system.
