The human brain consists of different types of areas, such as Broca鈥檚 and Wernicke鈥檚 areas. The former is located near the motor cortex, and the latter is located in the posterior part of the temporal lobe. Both are essential to the systematic functioning of the brain.

Broca鈥檚 area is associated with speech production, and Wernicke鈥檚 area is associated with comprehension of language. They both are connected to each other by arcuate fasciculus, a large bundle of nerve fibres. Thus, they both are essential for the production and comprehension of human language.

During the generation of speech, Broca鈥檚 area, located near the motor cortex, is activated. It also controls skeletal muscles such as that of the face. Wernicke鈥檚 area, located in the posterior part of the temporal lobe, is activated when speech is heard. It is involved in hearing.
