AUTONOMIC NERVOUS SYSTEM
The SYMPATHETIC (Fight-or-Flight) System:
Neurotransmitter: Norepinephrine & Hormone: Epinephrine (Adrenaline)
Adrenergic alpha and beta receptors

Neurotransmitter: Acetylcholine
Cholinergic muscarinic (M) receptors
Crash Course Anatomy & Physiology ANS Review Videos.
Hank takes you on a tour of your two-part autonomic nervous system. This episode explains how your sympathetic nervous system and parasympathetic nervous system work together as foils, balancing each other out.
Hank tries not to stress you out too much as he delves into the functions and terminology of your sympathetic nervous system.
This week we are looking at your parasympathetic division, which is the "resting and digesting" unit. Unfortunately, learning about this de-stressing division also involves a whole lot of memorization. Don't worry, though - we've got some mnemonic devices to help you out!
Girl in the Forest Mnemonic Video
This is Dr. Boyev's 3 minute video meant to help you remember the actions of the sympathetic (Norepinephrine, alpha and beta ADRENERGIC receptors) system. THere is no narration, only kick*ss music.
This is the mnemonic I use in my class to help students remember the actions of the sympathetic "fight or flight" nervous system. So, students of mine: After you watch this, go watch the Crash Course for Autonomic Nervous System Episodes A & P 13 and 14.
