Parasympathetic Nervous System - Structure, Function, and Outflow

Learn about the parasympathetic nervous system in this 20-minute educational video. Explore the general structure, compare sympathetic and parasympathetic systems, and understand neurotransmitters involved. Dive into the craniosacral outflow, examining both cranial and sacral parts in detail. Gain insights into the system's role in "rest-and-digest" functions, including effects on heart rate, digestion, and organ function. Discover how the parasympathetic system works antagonistically yet sometimes complementarily with the sympathetic system to maintain bodily homeostasis.
