Cerebral hemisphere

Dr Rohit Sharma and Dr Henry Knipe et al.

The two cerebral hemispheres are divided in the midsagittal plane by the interhemispheric fissure. Together they fill most the intra-cranial cavity.

Gross anatomy

The medial surface of each cerebral hemisphere is flat, the inferior surface is irregular and even slightly concave anteriorly, while the lateral surface is convex. They are all lined by cerebral cortex. 

The surface of the cerebral hemisphere is divided by grooves, called sulci, into ridges called gyri.

Each cerebral hemisphere is divided into four lobes of unequal size 4:

In addition to these four lobes, some authors refer to the insular cortex as the insular lobe, and the cingulate gyrus with hippocampus as the limbic lobe. 

The corpus callosum connects the right and left cerebral hemispheres. They are covered by the meninges
