    Thank you for all your great works, they made me finally understand how the anatomy of the nervous system works (incredible feeling) and saved me from constant cramming. Still I've got a question: what about anterior spinocerebellar tract? Do we mention it here, and in what area is it located? Or maybe I've got lost somewhere.. (I'm sorry for possible mistakes, English isn't my native language)

  • @TaimTalksMed

    @TaimTalksMed

    2 жыл бұрын

    Hello! Really good question! As far as I understood, the anterior spinocerebellar tract ascends up until the very caudal part of the midbrain before it enters the superior peduncle, therefore you rarely see it in cross sections (unless you cut at the very inferior part of it). You'll have to double check this for me, though! But after studying these things for countless hours; that's what I concluded with =) Your english is great!

    what i dont really understand: at 7:04 you divided the horizontal cut of the midbrain into the tectum and tegmentum (and cerebral peduncles) , which is correct and the same in the literature but to my knowledge, tectum is latin for "roof". since this is a horizontal cut of the tectum of the midbrain, wouldn't what is named "tectum area" of this cut just be the dorsal part of the horizontal cut of the tectum of the midbrain?

  • @Melancholy308

    i guess alternatively, im wrong because this is actually a coronal cut of the midbrain, but portrayed horizontally only for simpler display? and therefore I'm always mislead by its orientation?

    The main ones are of course the ones you see when you first google basal ganglia 🙂 but there are many(!) other structures that are considered a part of the basal ganglia aswell due to their interactions with their pathways 💪🏽 And the more the subcortical nuclei are studied the more the list expands!
