Surface of Cerebral Hemispheres
Surface Features of the Cerebral Hemispheres:
1. The cerebral hemispheres are furrowed by sulci and bridged by ridges or folds called gyri.
2. Identify the: Lateral sulcus or Sylvian fissure.
3. Identify the: Central sulcus or Rolandic fissure.
4. The two hemispheres are divided into four lobes: frontal, parietal, occipital and temporal.
5. The insula is covered by the opercula.
6. A massive white band of white matter joins the two hemispheres.
7. The cerebral hemispheres are made up of white and grey matter.
8. Two important dural septa must be recognized:
a. Falx cerebri: extends down into the longitudinal fissure between the cerebral hemispheres.
b. Tentorium cerebelli: separates the occipital lobes from the cerebellum.
9. The diaphragma sella forms an incomplete lid over the hypophysis in the sella turcica. The pituitary stalk passes through the opening in the diaphragma.
10. Identify the pre- and postcentral gyri responsible for the primary motory and sensory cortices.
