Mother's Day Special : Full Notes Motor Neurone

From the previous post, we know that then function of motor neurone (efferent neurone) is to transmist impulse from CNS to effectors. Now, we shall go detail about this nerve cell. Here are your two things you should know:

1) You should know the labels...

Yup, together with the direction of impulse (shown with red breaking arrow)

2) You should know the labels' functions...

Speaking of nodes of Ranvier (NOR), diagram below shows how it works:
The impulse seems to 'jump' across the NOR to gain the speed.

Finally, we just realized a special relationship between the myelin sheath & the axon. Here is how I put it :-)
