CT Brain Surface Anatomy - Video Lesson

Everybody, welcome back. This lesson is about the surface anatomy of the brain. We'll evaluate the surface anatomy using an illustration. This colorized illustration of the brain in the lateral position shows us the surface anatomy of the brain, including the general anatomy of the cerebrum and cerebellum. The cerebrum is the largest aspect of the brain. It's divided into right and left halves or hemispheres. In this illustration, we're only looking at the left side, but the right side of the brain is an identical mirror image. Notice that the cerebrum is divided into several lobes, indicated by different colors. We'll talk about those shortly. The most posterior and inferior segment of the brain is called the cerebellum. It is also divided into right and left halves. We're seeing the left side, but the right side is an identical mirror image. So what about these lobes? The frontal lobe is the most anterior aspect of the cerebrum. The frontal lobes are positioned
