The motor speech center is located in the inferior frontal gyrus of the left hemisphere of the brain near the lateral fissure, also known as Broca’s area. The language center is divided into sensory language center, motor language center, reading language center and writing language center. These centers are responsible for listening, speaking, reading and writing, respectively. If the motor language center is damaged, motor aphasia will occur. It is characterized by the presence of language expression disorders, normal language comprehension, inability to express names, often accompanied by varying degrees of reading and writing disorders, and so on. It is recommended that patients with damage to the motor speech center should consult a doctor in a timely manner and be treated under the guidance of a professional doctor to avoid adverse consequences.
