Final answer:
Broca's area is the specialized motor speech area located at the base of the precentral gyrus in the frontal lobe.
Step-by-step explanation:
The specialized motor speech area located at the base of the precentral gyrus which is responsible for controlling movements of the structures of speech production is called Broca's area. It is located in the lateral aspect of the frontal lobe, just anterior to the region of the motor cortex associated with the head and neck. Broca's area is named after Paul Broca, a French surgeon and anatomist who studied patients with difficulties in speech production.
