Upper motor neuron syndrome - Wikipedia
Upper motor neuron syndrome (UMNS) is the motor control changes that can occur in skeletal muscle after an upper motor neuron lesion. Following upper motor neuron lesions, affected muscles potentially have many features of altered performance including:

Upper Motor Neuron - an overview | ScienceDirect Topics
An upper motor neuron is defined as a neuron with its cell body in the cerebral cortex that descends through the brainstem and spinal cord to innervate lower motor neurons in the ventral horn, ultimately leading to the activation of target muscles.
