You know, In case of accident my blood type is Corona Extra shirt and hoodie So reduced power is Hallmark of Pyramidal tract pathology, differentiating it from Extra-Pyramidal Tract as later has no role in execution of the motor plan. If power is normal in a patient with movement disorders, think of basal ganglia or cerebellum. If power is reduced , think of pyramidal tract lesions. Cortex and cortico spinal tract try to suppress reflexes and tone by sending inhibitory signals to spinal cord anterior horn. This anterior horn motor neurones and peripheral nerves are responsible to maintain tone and reflexes. So if tone and reflexes are Increased, it means disease is either in motor cortex or in cortico spinal tract.
In case of accident my blood type is Corona Extra shirt, hoodie, sweater and v-neck t-shirt
Bets In case of accident my blood type is Corona Extra shirt
If tone and reflexes are decreased, In case of accident my blood type is Corona Extra shirt cortico spinal tract is affected. Dense hemiplegia would favour later where as partial hemiplegia/ monoplegia would favour motor cortex. Seizures or altered conscious state would favour motor cortex. Cortico spinal tract runs through corona radiata, internal capsule and brain stem. If there is lower motor type involvement of cranial nerves ( CN) along with dense hemiplegia , it favours brain stem ,Otherwise dense hemiplegia without lower motor type involvement of CN means internal capsule (IC) is most likely location. Facial nerve involvement of upper motor type also means IC lesion.
