[h] Neurology System Flashcards

[i] Master this session in just 5 minutes.

[q] Lesions of UMN (corticospinal tract) before the pyramidal decussation results in muscle weakness seen in muscles on the (ipsilateral or contralateral) side of the body (at the level or below the level of the lesion).

[f]IGlwc2lsYXRlcmFsLCBiZWxvdyB0aGUgbGV2ZWwgb2YgdGhlIGxlc2lvbi4=[Qq]

[q] A lesion to any part of a lower motor neuron will result in an (ipsilateral or contralateral) muscle weakness (at the level or below the level of the lesion).

[f]IGlwc2lsYXRlcmFsLCBhdCB0aGUgbGV2ZWwgb2YgdGhlIGxlc2lvbi4=[Qq]

[q] Hypertonia in pyramidal tract lesion (UMNL) is called ……….., but hypertonia in extrapyramidal lesion (basal ganglia lesion) is called ………?

[c]IFNob3cgbWUgdG hlIGFuc3dlcg==[Qq]

[f]IHNwYXN0aWNpdHksIHJpZ2lkaXR5Lg==

[q] Lesion of (upper motor neuron or lower motor neuron) leads to decreased muscle tone (flaccidity) at the level of the lesion, with wasting of the muscles.

[c]IFNob3cgbWUgdG hlIGFuc3dlcg==[Qq]

[f]IExNTkwu

[q] Lesion of (upper motor neuron or lower motor neuron) leads to exaggeration of deep reflexes (hyperreflexia) below the level of the lesion.

[c]IFNob3cgbWUgdG hlIGFuc3dlcg==[Qq]

[f]IFVNTkwu[Qq]

[q] Lesion of (upper motor neuron or lower motor neuron) leads to diminution of deep reflexes (hyporeflexia) at the level of the lesion.

[c]IFNob3cgbWUgdG hlIGFuc3dlcg==[Qq]

[f]IExNTkwu[Qq]

[q] What are the spinal segments that is most likely affected in case of absent biceps reflex?

[c]IFNob3cgbWUgdG hlIGFuc3dlcg==[Qq]

[f]IEM1LCBDNi4=

[q] What are the spinal segments that is most likely affected in case of absent Triceps reflex?

[c]IFNob3cgbWUgdG hlIGFuc3dlcg==[Qq]

[f]IEM2LCBDNywgQzgu

[q] What are the spinal segments that is most likely affected in case of absent Patellar reflex?

[c]IFNob3cgbWUgdG hlIGFuc3dlcg==[Qq]

[f]IEwyLCBMMywgTDQu

[q] What are the spinal segments that is most likely affected in case of absent Achilles reflex?

[c]IFNob3cgbWUgdG hlIGFuc3dlcg==[Qq]

[f]IFMxLCBTMi4=

[q] + Babinski sign (dorsiflexion of the big toe and fanning of the other toes) is seen in cases of (upper motor neuron lesion or lower motor neuron lesion).

[Qq]

[q] Lesion of the dorsal column – medial lemniscus pathway in any part along the entire length of the spinal cord will result in (ipsilateral or contralateral) loss of vibratory and proprioceptive sensation and below the lesion, while lesion in brain stem or above (after the 2nd order neuron crosses) will result in (ipsilateral or contralateral) loss below the level of the lesion.

[c]IFNob3cgbWUgdG hlIGFuc3dlcg==[Qq]

[f]IGlwc2lsYXRlcmFsLCBjb250cmFsYXRlcmFsLg==

[q] Lesions of spinothalamic tract in the spinal cord or brain stem will result in (ipsilateral or contralateral) loss of pain and temperature because the 2nd order neuron crosses almost as soon as it enters the spinal cord.

[c]IFNob3cgbWUgdG hlIGFuc3dlcg==[Qq]

[f]IGNvbnRyYWxhdGVyYWwu

[q] Thoracic and early lumbar sections contain ………, which are made up of sympathetic preganglionic neurons.
