I wish he was my teacher. So good at explaining clearly and quickly.
This video is well made. I usually can’t stay focused.

Don't stress
Great episode. Really helped consolidate learning! Keep it up.

I tried to preserve the first few letters for as many words as possible, so that you can differentiate the order of nerves that start with the same letter.
Great Revision video for Neurology. Thank you Hank.
god bless you and thank you for this excellent explanation
Anyone here in 2020 trapped inside their house because of COVID-19?

I'm having issues with autonomic nervous system for years. This helped me to understand my situation better. Thanks.
What does A&P stand for?
0:11 to 0:18 WTH?! LOL
This dude is really good, but talks too damn fast lol
The ANS is part of the peripheral nervous system, but not the motor pathway. Your chart should show the somatic and autonomic nervous systems under the peripheral nervous system, with sensory and motor pathways under somatic and parasympathetic and sympathetic under autonomic.
aren't post-ganglionic neurons that have a junction with a skeletal muscle always cholinergic? The sympathetic and parasympathetic divisions of the autonomic nervous system only affect smooth muscle and glands involuntarily. He should have said that adrenergic post-ganglionic neurons connect with what is covered with smooth muscle such as blood vessels. Isn't it that norepinephrine causes vasoconstriction, which increases BP, which allows skeletal and cardiac muscle to work faster (breathing, heart rate, blood to muscles)?
Very helpful in clarifying what I've been struggling to learn. Thank you!
obrigada pela legenda em portugues
Please make Indonesian subtitle
the unit on the autonomic nervous system is my weakest, so this really helps! i may not know everything thats on our objectives but at least i have a base understanding going into the test! can't know everything, right?
