The surface of the cerebral hemispheres consists of ridges and grooves. The shallow grooves are called Sulci.
<h3>What is Cerebral Hemisphere?</h3>
The brain is formed by two cerebral hemispheres. It is separated by a groove called longitudinal fissure. The brain is divided into left and right cerebral hemispheres. These consist of an outer layer of gray matter called the cerebral cortex which is supported by an inner layer of white matter.
In placental mammals, the hemispheres are connected by the corpus callosum which is a very large bundle of nerve fibers.
There are three poles of the cerebral hemispheres:
1. The occipital pole
2. The frontal pole
3. The temporal pole
The thin layers of cells that cover the cerebral hemispheres are called the cerebral cortex. These raised ridges of tissue on the surface of the cerebral cortex are known as gyri while the shallower grooves are called sulci.
Thus, the surface of the cerebral hemispheres consists of ridges and grooves. The shallow grooves are called Sulci.
