What are the symptoms and signs of the upper motor neuron lesion (cortex, internal capsule, brainstem, spinal cord) ?
Neurologist: The physical exam findings will be more difficult to see, but a neurologist will be able to examine the patient and might elect to do testing such as an EMG which tests the conduction of the nerves. ...Read more

If the higher brain centers become damaged, these primitive responses return because they are no longer being suppressed. Hope this helps to simplify the prior excellent answer. ...Read moreSee 1 more doctor answer
Lesion Localization: The upper motor neurons also called “Cortical Motor Neurons” are located in the motor cortex of the brain. The the spinal motor neurons are the lower motor neurons. Signs of UMN is a stiffness and resistance to movement. Signs of LMN damage include weakness, muscle atrophy. Hope it helps. ...Read more
Weakness: Motor neuron diseases affect the nerves that send the impulse to muscles to initiate movement. Examples of motor neuron diseases include lou gerig's disease(als) and spinal muscular atrophy. Symptoms may include limb weakness, difficulty swallowing, and difficulty breathing. Some types may also affect eye movement and facial expression. ...Read moreSee 1 more doctor answer
Neurons transmit sig: neurons transmits electric . They also process and transmit information between two cells. or introduce synapses, the specialized sites where neurons send and receive information from other cells, They also allow groups of neurons to coordinate complex processes.Without neurons, central nervous system does not function. Schwann cells lay down myliene around it which protects it and helps in fas ...Read more
