parasympathetic nervous system

par·a·sym·pa·thet·ic nerv·ous sys·tem

ˌ/parəˌsimpəˈTHetik ˈnərvəs ˈsistəm/

Noun

The parasympathetic nervous system can be thought of as a “brake” to the sympathetic system “accelerator”. Another term for the parasympathetic system is the “feed and breed” response system, which helps to describe its function. When activated, the body slows down, focusing its attention to building reserves by encouraging digestion and rest. The body also uses the parasympathetic response system to initiate the sexual responses necessary for intercourse and ultimately, reproduction.
