kick Goals (gracilis) with your feet
Cook and eat (cuneatus) with your hands
i remember gracilis is for legs by saying i have graciously long legs and they are inside while arms can spread out to remember their orientation on the spinal cord
I remember it as gracilis = grass so feet haha
Just to add found on page 492 on FA 2018.
Could someone please explain why you were able to eliminate the spinocerebellar tracts?
@fulminant_life because the mean age is 3.8 with a standard deviation of 1.8. An age of onset of 9 years is nearly 3 standard deviations above the mean. Therefore, since we know +/- 2 SD covers 95% of the bell curve, it must be higher than that. The only option higher than 95% is 99%.
Yes 9.2 was the upper limit for 99% CI. I picked 95 first because i thought 2.5% would be out of this range. But changed ans because it should be less than 2.5% because 9.2 is so close to 9. Also they are asking CLOSEST to which of the following?
The Boards and Beyond video of SC strokes was really helpful at explaining this if you are a video kind of person!
What pushed me away from pons was "dysarthric speech" which implied she still could speak to some degree.... which made me pick medulla.
I think FA may be misleading. Primarily it will effect the Pons because that is where the majority of the Basilar Artery is located. and I guess it could effect the other locations? but everywhere I have looked Locked-in syndrome is an issue with the Pons. But someone please continue to clarify, cause I was a bit tripped up at first with this question
Although FA says it can be pons, medulla, or lower midbrain, "locked-in" syndrome generally arises from BL pons lesions. Another way you can rule out medulla and midbrain in this question is the ocular movement findings. Since the patient has impaired horizontal gaze BL, you can conclude that the Abducens nuclei are involved on both sides. The abducens nuclei are located in the pons.
USMLE secrets also states that it is most commonly in the pons
Bates states that locked-in syndrome preserves consciousness but these patients have limited speaking ability
