Upper and lower motor neuron lesions cause very different clinical findings. Upper motor neuron lesion are lesions anywhere from the cortex to the descending tracts. This lesion causes hyperreflexia, spasticity, and a positive Babinski reflex, presenting as an upward response of the big toe when the plantar surface of the foot is stroked, with other toes fanning out. Collects the transmitted motor impulses from the upper motor neuron and conducts them to the muscles in the body. Cell bodies of upper motor neurons are bigger than lower motor neuron cell bodies. Cell bodies are comparatively smaller than the upper motor neurons. Classified on the basis of the type of muscle fibre they innervate. lesion of the motor or sensory portion of the femoral nerve or severe disease of the quadriceps muscle.
