Medial view of the brain
This study unit will teach you how to:
- Identify the 3 parts of the brain.
- Name and demarcate all the visible structures on the medial view of the brain.
- Describe the main gyri and sulci seen on the medial view of the cerebrum.
The brain is the most complex organ of the body and it is composed of the cerebrum, brainstem and cerebellum. The largest part of the brain is the cerebrum, separated by a deep fissure, called the longitudinal fissure, into two hemispheres. If we make a section starting from the longitudinal fissure and continue down to the midline (a section known as a midsagittal section), we will separate the two hemispheres and we will be able to see the brain from a medial view.
In this view, we can see the cerebrum which is the most superior part of the brain and is organized into folds called gyri and grooves called sulci. In this study unit, you will learn all the gyri and sulci of the cerebrum that are visible from a medial view. Below the cerebral lobes, we can see the corpus callosum that “connects” the two hemispheres and the diencephalon with its different structures below it.
The most inferior part of the brain is the brainstem. In the midsagittal view, we can see the three parts of the brainstem (the midbrain, the pons and the medulla oblongata). Finally, the last part of the brain is the cerebellum, which can be seen posterior to the brainstem.
