Neuroanatomy Video Lab – Brain Dissections: Motor Systems
[38:16]
A comparison of the three major motor systems focuses on categorizing motor problems as corticospinal tract, cerebellar, or basal ganglia. It begins with 12 minutes of gross anatomical structures and pathway review followed by clinical video clips demonstrating clinical features of disease of each of the three major circuits. Clinical signs and symptoms include: hemiparesis, spasticity, Babinski, clonus, atrophy, fasciculations, limb ataxia, dysmetria, intention tremor, rapid alternating movements, pendular reflexes, hypotonia, titubation, nystagmus, resting tremor, bradykinesia, athetosis, chorea, tardive dyskinesia, rigidity and retropulsion.
