Discover A Simplified Approach to Master the Complexity of Anatomy with me, Dr. David Morton ... The Noted Anatomist!
------------------------------------------------------------------
This video tutorial briefly covers the sympathetic and parasympathetic role on heart innervation. It focuses on the following:
- Sympathetic neurotransmitters (epinephrine and nor-epinephrine) and receptors (adrenergic).
- Parasympathetic neurotransmitters (acetylcholine) and receptors (muscarinic).

Thank you! Could in theory a sympathetic fiber be activated through ephaptic coupling with (and by) a parasympathetic fiber that for some reason happened to have been moved close to it?

You should show the proper length of pre amd post ganglionic neurons like In sympathetic nervous system the pre ganglionic neuron is shorter than post ganglionic neuron and vise versa.. By the way all over great and simple work.👍

we're doing cardio which you don't have a lot of videos for so here I am rewatching this video just to get my TNA fix :)

does sympathetic stimulation shortens pr interval?

@plickaplicka7 6 жыл бұрын

I don't think parasympathetic innervation of the heart results in a decrease in contractility or conduction velocity. According to the Oxford handbook of medical sciences (p. 421 of 2nd edition) it has no appreciable effect on contractility.

Jack Brophy yup because PNS only innervates the nodal and not the contractile cells.
