Neurology - Upper Motor Neuron vs Lower Motor Neuron Lesion

Explore the pathophysiology and characteristics of upper motor neuron (UMN) and lower motor neuron (LMN) lesions in this comprehensive neurology lecture. Delve into the causes, terminology, and key differences between UMN and LMN lesions, including fasciculations, muscle tone, and reflexes. Examine the corticospinal pathway and medullary reticular nuclei to understand their roles in motor function. Learn about spasticity, rigidity, and special tests used to differentiate between UMN and LMN lesions. Gain valuable insights into this crucial aspect of neurology to enhance your understanding of motor neuron disorders and their clinical presentations.
