The Midbrain🧠 can be such a fun place for neurology, but sometimes we get bogged down in fancy words instead of enjoying the syndromes. Let's review some basic Midbrain Anatomy together! #MedTwitter #NeuroTwitter #MedEd #neurology #medstudent #MedStudentTwitter #tweetorial
1: Let's first get the dorsal and ventral sides straightened out! I remember that I can draw✏️ a 'D' on the colliculus and a 'V' in the interpeduncular fossa to know what's ⬆️ and ⬇️. Phew easy so far! 🤗
2: I can attempt to remember the latin roots for Tectum ('roof') and Tegmentum ('covering') 🤔 OR just remember that the "teCtum is the Cap where the Colliculi Collect" and "tegMentum is the Meat of the Midbrain."😉
3: Success so far! 🤗 Let's place the major tracts. Cranial Nerve III helps control most the eye movements 👀, Red Nucleus helps with balance/coordination 🤹, and the Corticospinal Tract is the major motor pathway🦵.
Now the fun stuff 🥳 The classic syndromes of the midbrain all involve cranial nerve III 👁️ -> all resulting in ipsilateral oculomotor palsy. The differences come down to the other tracts involved....
4: Weber Syndrome will leave you WEAK, because of involvement of the corticospinal tract. 👎🦵
5: Claude Syndrome will leave you CLUMSY, because of involvement of the red nucleus. 👎🤸
6: Benedikt Syndrome will be BOTH, because of the involvement of the entire midbrain tegmentum. 😩🥴
And that's how I remember the midbrain 🧠. Such a fun part of the brain to hang out 😊. Hope you had as much fun as me! 🎉
