GENERAL HISTOLOGY

Detailed explanation-1: -The lesions typically leading to Broca’s aphasia most often affect both the inferior frontal lobe and the anterior inferior portion of the parietal lobe; this is generally more extensive than the part of the third (inferior) frontal gyrus and surrounds that have been identified as Broca’s area.

Detailed explanation-2: -Agraphia can occur in isolation, although it often occurs concurrently with other neurologic deficits such as alexia, apraxia, or hemispatial neglect. Agraphia is an impairment or loss of a previous ability to write and can result from a number of etiologies.
