Anatomy Of The Central Nervous System (Spinal Cord, Brainstem, Brain) | Full discussion

Hello, I just want to say how much I appreciate your videos. They’re super super helpful. I’m currently doing a PhD in neuroscience and I cannot tell you how much this complements everything that I’m learning. Keep up the great work!

Thank you so much!

this is the best thing I could have come across right before my exam thank you so much!!

[@sciencewithtal]

Thank you!! Good luck for your exam!

Thanks a lot!!

@@sciencewithtal the pyramidal tracts lack the corticobulbar tract🙃

[@sciencewithtal]

@@alhassan6280 You are right! Some of the resources I was using were omitting that tract, so I decided not to include it given that I was not covering it in detail anyway. I'll make sure to cover it whenever I'll make some content on the motor system. Thank you for pointing it out!

Could u please demystify this?! Somatic NS (involuntary) involves pain temperature sensors, if we touch a v hot object, we’d withdraw the subject involuntarily Here sensation is pain and temperature(somatic) but response aint voluntary its involuntary! Please explain, i never get the actual roles of ANS and somatic NS! THANK YOU

[@sciencewithtal]

Good question! In the context where you would burn yourself, the sensation of pain is somatic because it is pain afferents that are picking that up. While traveling towards the brain, these afferents also synapse in the spinal cord to mediate different reflexes (for ex the withdrawal of your hurt limb). As such, the involuntary part comes from the reflex mediated by the spinal cord because they occur much faster than any cognitive processes and this is why they seem involuntary. As far as I know, the autonomic nervous system is not engaged in these reflexes. Hopefully that answers your question!!
