During times of relaxation, the ______ division of the autonomic nervous system utilizes discrete and localized innervation, stimulating only one or a few structures at the same time.

Respuesta :

During times of relaxation, the parasympathetic division of the autonomic nervous system utilizes discrete and localized innervation, stimulating only one or a few structures at the same time.

In general, parasympathetic and sympathetic divisions are very similar to the preganglionic axons are myelinated, on the other hand  post- ganglionic axons are unmyelinated. When Parasympathetic nervous system (PSNS) is activated, this slows our heart and breathing rates, also lowers blood pressure .

Hence, parasympathetic part of your autonomic nervous system helps in balancing sympathetic nervous system. Sympathetic nervous system controls your body's fight or flight response, while  parasympathetic nervous system control body's response times of rest.
