Which structure is included in the frontal lobe?

• A. Postcentral gyrus
• B. Calcarine sulcus
• C. Precentral gyrus
• D. Superior temporal gyrus

Answer: (C)

The frontal lobe houses the primary motor cortex, which is located in the precentral gyrus. This region is responsible for initiating voluntary movements and sits just in front of the central sulcus, within the frontal lobe. The other structures belong to different lobes: the postcentral gyrus is in the parietal lobe and serves as the primary somatosensory cortex; the calcarine sulcus is in the occipital lobe and contains the primary visual cortex; the superior temporal gyrus is in the temporal lobe and handles auditory processing and language aspects. So, the precentral gyrus is the structure included in the frontal lobe.
