This video contains the introduction of the Autonomic Nervous System (ANS) and the basic difference between the Parasympathetic nervous system Vs Sympathetic Nervous System (Hindi & English)

Parasympathetic/Cholinergic System: the parasympathetic neurons are originated from Cranian Saceral part thus it also called as a Cranio-Saceral system. this system has long preganglionic and short postganglionic fibres. in the synaptic Junctions Acetylcholine is the major neurotransmitter. And This system is activated in the Condition of Rest and Digest.

This system has a short preganglionic and long postganglionic fiber. Noradrenaline is the major neurotransmitter. And this system is activated in the Condition of Flight, Fight, and Fright.
