Thank you Dr Srinavas. Your lectures are brilliant and concise, and it is an absolute joy to watch and learn. I am a neurology resident from South Africa and regularly view your informative videos. Please consider using a larger white board or an electronic board as the written text is difficult to see.
Conus medullaris contains spinal segments from S1 and below, so ankle jerks (S1, S2) will be affected in conus medullaris lesion. It will be absent coz here the ant horn cells will be affected It would have been brisk/exaggerated if there was a lesion above the level of S1 , with respect of which , all the nerves below that lesion will show umn like features
Sir u said in conus medullaris anterior horn cells are affected so fasciculations will be present.. cauda equine is also lmn type but u said no fasciculations can u explain sir ?
Sir thank u for making it as simple as possible. In conus u said, only ankle jerk may be absent. But why sir? As its UMN/LMN type, it can be exaggerated as well??
In a Cns lesion usually the higher the level of lesion the more is the damage, if conus is higher up as compared to cauda then why is there addition lumbar involvement in cauda equina syndrome(but it is a lower lesion as compared to conus?
At L1 vertibral body level spinalcord ends and contains sacral segments.below L1 there is no spinalcord there are only roots compraising L2 and Below know as CAUDA EQUINA.
Thank you sir, now so easy
Once was very tough to learn and memorize.

Welcome 👍
11:09 Saddle anesthesia is for conus medullaris right sir? Or for cauda equina.. Can you pls explain that part sir.
Except camera recording and writing.. Every thing is understandable
Sir,
In Conus Medullaris Syndrome, should the Ankle jerk not be Brisk since it is a UMN lesion.
But you said ABSENT! kindly clarify it please.
Conus medullaris contains spinal segments from S1 and below, so ankle jerks (S1, S2) will be affected in conus medullaris lesion. It will be absent coz here the ant horn cells will be affected
It would have been brisk/exaggerated if there was a lesion above the level of S1 , with respect of which , all the nerves below that lesion will show umn like features
Thanks
👍
Sir u said in conus medullaris anterior horn cells are affected so fasciculations will be present.. cauda equine is also lmn type but u said no fasciculations can u explain sir ?
Why there is no fasciculations in cauda equina?
❤❤❤❤❤❤❤❤❤❤❤❤
Sir thank u for making it as simple as possible.
In conus u said, only ankle jerk may be absent. But why sir? As its UMN/LMN type, it can be exaggerated as well??
CONUS S2,S3,S4 AND SOMETIMES S1 BUT NOT L2,L3,SO ANKLE JERK IS AFFECTED
@@dr.sreenivasmedicalconcept7185 ok sir. So ankle jerk can be absent or exaggerated, as conus can be UMN/LMN. Am I correct sir?
In a Cns lesion usually the higher the level of lesion the more is the damage, if conus is higher up as compared to cauda then why is there addition lumbar involvement in cauda equina syndrome(but it is a lower lesion as compared to conus?
At L1 vertibral body level spinalcord ends and contains sacral segments.below L1 there is no spinalcord there are only roots compraising L2 and Below know as CAUDA EQUINA.
@9:12 , sir fasciculations are present in LMNL. Cauda equina is LMNL type. Then why fasciculations are absent in CAUDA EQUINA SYNDROME?
Fasciculations are more commly seen in AHC
thank u sir
Welcome
Tough topic simplified
Thank you
well explained sir
Thanks and welcome
