CORRECTION: 2:17 Written on screen is "IX" where it should be "XII", hypoglossal nerve (audio correct). Also on protrusion of the tongue, the deviation is towards the side of the lesion (audio incorrect). Thank you to the people who commented!

Can someone explain to me why people say extrapyramidal tracts control automatic movements if some of them control conscious movement

Precise and informative 👍👏

Hello just wanna to ask Rubrospinal tract control voluntary flexor movement isn't?

You have made everything so much easier to understand; thank you. However, you said somethings respecting the CN that are very confusing for me. When you referred to the CN Hypoglossal, the tongue will not deviate away from the weak side on the contrary. When the PT protrudes the tongue (CN XII), it will deviate towards the weak side. On the other hand, when you test the CN X Vagus," Say Ahhhh," Uvula will deviate away from the weak side. if I am wrong please let me know. Thanks again.

Thank you for the comment! CN XII (hypoglossal), upper motor neuron lesions lead to the tongue deviating away from the side of the lesion due to a decussation before the CN XII nuclei causing a weaker genioglossus muscle on the contralateral side (i.e a left sided UMN injury will cause weakness of the right genioglossus, therefore the tongue deviates to the right- away from the lesion). A lower motor neuron injury would instead lead to deviation towards the side of the injury (left sided LMN injury would lead to a weaker left genioglossus, causing the tongue to deviate to the left- towards the lesion). Hope that makes sense! Thanks again 😁

You're not wrong though that was a different concept conveyed. To put it simply, the injury of 12 cn, which is a lmn injury will deviate the tongue towards the weak side as the genoglossus muscle deviates the tongue to opposite direction. So when injured its "deviation" will be lifted and the tongue will be pointing to weak side. An umn injury will have opposite affect. It is different from the 10 cn in which uvula is deviated on the opposite side as the muscle supplying it pulls it ipsilateral, unlike genoglossus. Hope this makes sense.

very comprehensive! thank you!

amazing video but contralateral nerve palsies divides into central and peripheral and central includes only Facial nerve VII and Hypoglossal XII not IX, thanks

You should mention that the extrapyramidal tract is heavy modulated by the motor nuclei, including the basal ganglia.

Hi Adam! Glad you enjoyed it, I have 2 other videos up on the ascending and descending tracts - I know they can be a pain to learn! All the best!

Does the medial vestibulospinal tract cross in the upper medulla and descend bilaterally?

Why damage on pyramidal UMNs increase muscle tone?

@01xmidhat11

Жыл бұрын

I think thats because the lower motor neurones are still working and undergo an adaptation which causes these lower motor neurones to become more excitable.

@uthayaavarshini2526

bcoz when there is no control over the LMN bcoz UMN has lesioned the LMN becomes uninhibited and release more neurotransmitter (im not sure wch exactly) wch act on muscle and causes sapstic paralysis whereas on LMN lesion the neurotran cant reach muscle fuber and results in flaccid paralysis

Not everything hundred percent true. Hypoglossal is CN XII not IX. And 90%of CST goes contralateral side (lateral) and 10% ipsilaterally (anterior)

This explanation is wrong, please be weary. Make sure to google properly from a proper source.

Doesn't make any sense ..fail to explain so many things
