Study Notes
Axial Section of Brain Stem at Pons Level
- The frontal lobes of the brain are separated by the interhemispheric fissure and the falx cerebri.
- The temporal lobe is located in the middle third of the section, separated from the frontal lobe by the Sylvian fissure.
- The pons is visible in the midline, separated by the interpeduncular cistern.
- The suprasellar cistern, located anterior to the midbrain, contains the internal carotid artery and its branches.
- These branches form the circle of Willis.
- The cerebellum and fourth ventricle are visible in the posterior part of the section.
