Cerebrum

Dr Sajoscha Sorrentino and Dr Jeremy Jones et al.

The cerebrum (or telencephalon) is paired structure composed of two hemispheres (left and right).

The cerebrum includes

It is connected to the brainstem via the cerebral peduncles.

Each cerebral hemisphere consist of the following parts:

The frontal lobe

The frontal lobe is seperated from the parietal lobe by the central sulcus and separated from the temporal lobe by the lateral sulcus.

The frontal lobe consists of the frontobase, the precentral gyrus and superior, middle and inferior gyrus.

The parietal lobe

The parietal lobe consists of the postcentral gyrus, the superior and inferior parietal lobule, the supramarginal gyrus and the angular gyrus.

The occipital lobe

The occipital lobe consists of the superior, middle and inferior occipital gyrus.

The temporal lobe

The temporal lobe consists of the superior, middle and inferior temporal gyrus.
