Answer 1

Aphasia is caused by injury to speech centre

Aphasia is an inability to comprehend or formulate language because of damage to specific brain regions

Wernicke's speech area, is located in the superior temporal gyrus in the dominant cerebral hemisphere, It is involved in the comprehension of written and spoken language.

Damage caused to Wernicke's area results in receptive, fluent aphasia or Wernickes aphasia. This means that the person with aphasia will be able to speak fluently by connecting words, but it will lack meaning

Broca's area is a region in the frontal lobe of the dominant hemisphere, usually the left, functions  which is involved in the production of language and speech.

Damage tp Brocas area leads to expressive aphasia, also known as Broca's aphasia, are individuals who know "what they want to say, but they are unable to express".
