The table below provides a summary of key upper motor neuron UMN and lower motor neuron LMN signs you may identify in an upper limb neurological examination. Hirayama is a rare nonfamiliar monomelic amyotrophy originally described by Dr.
The nucleus is situated in the caudal portion of the ventrolateral pontine tegmentumIts axons take an unusual course traveling dorsally and looping around the abducens nucleus then traveling ventrally to exit the ventral pons medial to the spinal trigeminal nucleusThese axons form the motor component of the facial nerve with parasympathetic and sensory components. Nerve roots peripheral nerve neuromuscular junction or muscle motor neuron lesion. The table below provides a summary of key upper motor neuron UMN and lower motor neuron LMN signs you may identify in a lower limb neurological examination.
