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?

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.

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.
