Which of the following brain areas is primarily responsible for voluntary motor control?

• A. Primary motor cortex
• B. Broca's area
• C. Wernicke's area
• D. Somatosensory cortex

Answer: (A)

Verified step by step guidance

1. Understand the function of each brain area listed: Broca's area is involved in speech production, Wernicke's area is related to language comprehension, and the somatosensory cortex processes sensory information from the body.
2. Recall that voluntary motor control refers to the conscious initiation and control of muscle movements.
3. Identify the brain area responsible for initiating voluntary movements, which is the primary motor cortex located in the frontal lobe.
4. Recognize that the primary motor cortex sends signals to muscles to produce voluntary movements, making it the key area for motor control.
5. Conclude that among the options given, the primary motor cortex is the brain area primarily responsible for voluntary motor control.
