Final answer:
The left cerebral hemisphere is primarily responsible for language processing, housing key areas such as Broca's area for speech production and integrating language with motor functions through connections such as the corpus callosum.
Step-by-step explanation:
The hemisphere primarily implicated in language processing is the left cerebral hemisphere. Language functions of the cerebral cortex are localized to the left hemisphere in approximately 95 percent of the population. This lateralization is a result of the specialization of functions in each hemisphere. Importantly, the left hemisphere is not only responsible for language processing but also houses Broca's area, which is a region of the frontal lobe associated with the motor commands necessary for speech production.
The left hemisphere is crucial as it is connected to the right side of the body and plays a role in integrating language with motor functions, such as the ability for a verbal command to initiate movement. The control of language by the left hemisphere is corroborated by the fact that the corpus callosum connects the two hemispheres, allowing for the integration of sensory and motor functions with language processing.
