Question 18

Broca’s Area

Answer 18

Question 19

Aphasia

Answer 19

Being unable to understand speech

Question 20

Wernicke’s area

Answer 20

Focused on understanding speech and assign words meaning

Question 21

Corpus Callosum

Answer 21

this is the middle of the brain. It links both hemispheres together and is in constant communication with both sides (women’s corpus callosum tends to be bigger than men’s). If the corpus callocum is severed can cause spilt brain which is eliminating the main communications amongst the hemispheres.
