GYRI OF THE BRAIN - LEARN IN 4 MINUTES

The brain has four lobes: frontal, parietal, temporal, and occipital. Let’s start examining the gyri of each lobe by first crossing off the ones that are easiest to remember. At the boundary between the frontal and parietal lobes is the central sulcus. The gyrus on the frontal lobe side of this sulcus is the precentral gyrus, while the gyrus on the parietal lobe side is the postcentral gyrus. Next, the frontal and temporal lobes each have a set of three gyri – superior, middle, and inferior. Superior frontal gyrus, middle frontal gyrus, inferior frontal gyrus. Superior temporal gyrus, middle temporal gyrus, inferior temporal gyrus. The occipital lobe is a similar situation, with the superior occipital gyrus, lateral occipital gyrus, and inferior occipital gyrus. Now, let’s get to the gyri that are harder to remember. Here you see the orbital gyri near the eye socket. The inferior frontal gyrus can be split into three sections – the pars orbitalis – closest to your eye socket, or orbit – the pars triangularis
