Which division of the autonomic nervous system is associated with 'rest and repair'?

The correct answer, the parasympathetic division, is known for its role in promoting 'rest and repair' activities in the body. This division of the autonomic nervous system is responsible for conserving energy and facilitating processes that occur when the body is at rest. It enhances bodily functions such as digestion, salivation, and urination, while also slowing the heart rate and promoting a state of relaxation.

The parasympathetic division operates through neurotransmitters like acetylcholine, which stimulate various organs and systems to restore energy and encourage healing and recovery processes. By countering the effects of stress or activity driven by the sympathetic division, the parasympathetic division helps maintain homeostasis and supports restorative functions after a period of stress or exertion.
