The Cerebrum Flashcards
The cerebrum is divided into two: what are they and what do they form?
- Diencephalon - forms the central core.
- Telencephalon - forms the cerebral hemispheres.
What is the surface of the cerebral hemisphere covered by?
Cerebral cortex
What divides and partially connects the cerebral hemispheres
Divider - median longitudinal fissure
Joiner - corpus callosum
What are the poles of the cerebrum?
Frontal
Temporal
Occipital
What are the surfaces of the cerebrum?
Superolateral
Medial
Inferior
The inferior surface of the cerebrum is subdivided into
Orbital surface
Tentorial surface
What are the 3 sulci on the superolateral surface of the cerebrum?
Central sulcus/ Rolandic sulcus
Lateral sulcus/Sylvian sulcus
Parieto-occipital sulcus
What are the four main lobes of the cerebral hemisphere
Frontal
Parietal
Occipital
Temporal
What’s another name of the insula/insular lobe?

Precentral sulcus
What are the divisions of the inferior frontal gyrus?
