Question: 182
2. Which area of the brain is responsible for coordinating complex motor functions?
- A. Frontal lobe
- B. Occipital lobe
- C. Reticular activating system
- D. Cerebellum
Correct Answer: D
Explanation:
The cerebellum, located behind the pons and below the cerebrum, receives input from the primary motor cortex in the forebrain, and coordinates complex motor function (choice D is correct). The frontal lobe contains the primary motor cortex, which is responsible for initiating movement, but does not coordinate complex motor functions (choice A is wrong). The occipital lobe is responsible for vision (choice B is wrong) and the reticular activating system is responsible for arousal and wakefulness (choice C is wrong).
