What is the importance of examining motor system?
Examination of the motor system. Clinical assessment of the motor system requires intuition and patience. The test will help the clinician to determine whether or not the lesion is occurring in the upper motor neuron versus the lower motor neuron.
What is a motor system assessment?
The motor system evaluation is divided into the following: body positioning, involuntary movements, muscle tone and muscle strength. Upper motor neuron lesions are characterized by weakness, spasticity, hyperreflexia, primitive reflexes and the Babinski sign.
What is the purpose of the motor system?
The motor system must generate movements that are adaptive and that accomplish the goals of the organism. These goals are evaluated and set by high-order areas of the brain. The motor system must transform the goals into the appropriate activations of muscles to perform the desired movements.

Where is the motor system in the brain?
frontal lobesThe brain's motor system is contained mostly in the frontal lobes. It starts with premotor areas, for planning and coordinating complex movements, and ends with the primary motor cortex, where the final output is sent down the spinal cord to cause contraction and movement of specific muscles.
What are the different motor systems?
The four medial motor systems are the anterior corticospinal tract, the vestibulospinal tract, the reticulospinal tract, and the tectospinal tract.
Where is the motor system?
The primary motor cortex, or M1, is located on the precentral gyrus and on the anterior paracentral lobule on the medial surface of the brain. Of the three motor cortex areas, stimulation of the primary motor cortex requires the least amount of electrical current to elicit a movement.
What does a neurologist look for when examining a patient?
What is a neurological examination? A neurological examination assesses motor and sensory skills, hearing and speech, vision, coordination, and balance. It may also test mental status, mood, and behavior. The examination uses tools such as a tuning fork, flashlight, reflex hammer, and a tool for examining the eye.
