The collection of cell bodies in CNS is *BASAL GANGLIA*
That's the only ganglia found in CNS
Much excited for the neuroanat series 🤟🏽
Now, answers to the Qs:
1. First one - Ganglia contain the cell bodies or soma of the first order sensory neurons while soma of the second order sensory neurons are present as nuclei within the CNS, with one exception; probably 5th in line within this series... the mesencephalic nucleus of Trigeminal.
2. For the parts of ethmoid... first there's a cribriform plate; then 2 extensions from the middle, one up and another going down... they would be Crista galli and Perpendicular plate of ethmoid respectively. And on either sides there shall be 3 to 4 rows of ethmoidal air cells. Ethmoid would also make portions of the nasal conchae and definitely the bony parts of nasal septum...
3. Amphotericin B and Azoles; they are cell membrane inhibitors, targetting Ergosterol. One would inhibit its synthesis while the other shall sequester it... Need to brush up on these...

Bro drops the hardest lectures and thought we won't take notes 🔥
It's finally time for my brain to learn about itself💯😅 thank you Perfectionalis✌🏿
My pleasure!
Thx for the neuro content ❤ Hope you'll doing more of these🙏
Sure!
Ganglia inside CNS - Basal ganglia
The “basal ganglia” are not actually ganglia, but nuclei.
Modern texts actually refer to them as “basal nuclei”.
The former terminology is considered outmoded and inaccurate.
Haha u are wrong. 😂😂
Finally
Recently I watched an old video of yours and you were thinking of making a neuroanatomy playlist
Hope you like it!
One correction:
CN 1 is SSA and not SVA.
SVA: CN7- carrying taste from anterior two-third of tongue
CN9- carrying taste sensation from posterior one-third
CN10- carrying taste sensation from epiglottis
I’m left speechless once again by the quality and approachability of this video. Sending kudos. ❤
And my guess with ganglion in CNS: retinal ganglion cells?
I immediately thinking about cranial nerves III, IV, VI, and how these nerves coordinate movement like eye tracking and reflexes
Dear Medicosis,, i am just addicted to your all videos...Bcoz it's in detail and well explained... But one request please make it Little SIMPLE and SLOW such that everyone can understand.... Specially neurology playlist... please
Thank you for your honest feedback!
Great video! Thank you!!
Thank you 🙏
THANK YOU SOO MUCHH !! THIS WAS MORE THAN PERFECT
Thank you! I hope you like the upcoming neuro videos!
Great lecture sir...🎉...
Thank you!
Hello Sir
Personally, I'm not technically a medical student but fall under biomedical science degree category
(Were I live, we can study medicine straight out of secondary school but I didn't make the cut so I decided to go with a biomedical degree first)
Because of time and the curriculum of my degree, I can't watch all of your videos as I don't do some courses you teach (That will change hopefully when I start my medical degree)
Anyway sir, where I'm going with this is to say thank you and even though I don't watch all your videos, I just wanted to let you know you are very much appreciated sir and If chanced, I would watch as many of your videos as I possibly could
Thank you!
I wish you all the success in the world!
Bro pls I want membership lectures@@MedicosisPerfectionalis
I WISH I COULD BUY ALL OF YOUR LECURES
ganglion in cns is basal ganglia
please medicosis keep them coming just in time for a neuranatomy committee 😢
Thank you for letting me know!
I wish you success!
Could co-v1d 19 induced Anosmia be Trigeminal nerve dysfunction... Especially if numb in just 1 nostril? and what could be potential therapy options to look into (4 years on)
Thanks!
My pleasure!
Hi Medicosis, thank you for your videos they have been helpful in my medical journey. I have a question, you mentioned after SVA, SSA and you said special sensory afferent but sensory is same as afferent. Isn’t it supposed to have been Special somatic afferent? If no, please enlighten me so I'd know why. Thank you for your response 😊
Both are correct! Different books use different classification terminology. I've talked about this in later videos in this neuroanatomy playlist.
Big like 🌹
Big thanks!
is basel ganglia an example for a ganglion that's in the CNS?? i know it's located in the cerebrum
Excellent!
يعطيك العافية بس دخلت شعبان برمضان فجاه صرنا مايكرو
Are you from egypt
In the "Autonomic nervous system" video, in the third minute you said that there is no such thing as "autonomic sensation", but in this video you said the opposite
Was the statement in the 1st video a mistake?
Yeah! The first video was a mistake…I corrected that mistake in a subsequent video in my physiology playlist. The truth is that autonomic can be sensory or motor. Thank you so much for being so attentive.

Thank you for this truly helpful content
It feels illegal watching this masterpiece for free
I appreciate you!
🩺🎓👍
Thank you!
Please remove membership restrictions on video thing so can watch it free.
It's been tough I know
