GENERAL HISTOLOGY

Detailed explanation-1: -Ipsilateral hemiplegia is occasionally caused by medullary lesions or by secondary damage of the cerebral peduncle contralateral to the lesion (Kernohan’s notch). There are few reports of ipsilateral hemiplegia or hemiparesis caused by a supratentorial cerebral lesion.

Detailed explanation-2: -Hemiparesis ipsilateral to the facial paralysis suggests a cortical or subcortical lesion, whereas contralateral hemiparesis suggests a pontine lesion near the facial motor nucleus.

Detailed explanation-3: -Classic signs of an ACA stroke are contralateral leg weakness and sensory loss. Be sure to evaluate lower-extremity strength and sensation.

Detailed explanation-4: -Hemiplegia is usually caused by brain damage localized to the cerebral hemisphere opposite the affected side. For example, injury to the left side of the brain will cause right hemiplegia and vice versa.
