NBME 13progressive weakness, dec strength, hand muscle atrophy, diffuse hyperreflexia and fasciculations on hands and arms, normal sensory exam; - correct answer amyotrophic lateral sclerosis (ALS) --death of both upper and lower motor neurons in the motor cortex of the brain, the brain stem, and the spinal cord --Stephen Hawking disease --*UMN and LMN signs* --rapidly progressive weakness with fasciculations eventually leading to muscle atrophy, spasticity, dysarthria, dysphagia, respirato...

Upper Motor Neuron (UMN) correct answers -Begins and terminates in the CNS. -Utilized by the pyramidal and extrapyramidal systems. Lower Motor Neuron (LMN) correct answers -Begins in the ventral horn of the spinal cord (corticospinal) or the brainstem (corticobulbar) and terminates in the neuromuscular junction. -Acts as a link between UMNs and muscles UMN Lesion - Tone correct answers Increased UMN Lesion - Reflexes correct answers Increased UMN Lesion - Fasiculations correct answ...

NWHSU NDX Final Exam Questions with Accurate Answers A study by Rubinstein, et al. defined a group of clinical exam tests that could identify the presence of cervical spine radiculopathy when there is no evidence of neurological deficit. These tests included all of the following EXCEPT: a. upper limb tension b. Neer's test c. spurlings d. cervical spine distraction e. upper limb tension Neer's test Among the general population, musculoskeletal pain and injury rank second only...
