Part 3: Multiple-Choice Self-Test
Any student of the nervous system needs to recognize the main structures and landmarks found on the outside of the brain and the general placement of major structures found deep within the brain. Tutorial 19 illustrates some of these regions as seen from a coronal section through the brain (Figure 19a) and from the ventral surface of the brain (Figure 19b). A coronal section is one that separates the brain into anterior and posterior halves. The coronal section shown in Figure 19a occurs approximately halfway between these two poles, and helps to show the placement of some of the major internal structures of the brain that will be referred to elsewhere. The ventral view of Figure 19b identifies several major structures that appear on the bottom surface of the brain.
To develop a three-dimensional representation of the brain, several perspectives need to be considered. In addition to the coronal section and ventral surface views of the brain described in this tutorial, a mid-sagittal section and lateral surface view of the brain should also be studied. A mid-sagittal section through the brain separates this structure into left and right halves. The major regions and landmarks located on the mid-sagittal surface of the brain are illustrated and identified in Tutorial 20. The structures located on the lateral surface of the brain are illustrated and identified in Tutorial 21.
