What is Medulla

The human brain is a very complex entity with a distinctive organisation and function. There are three main structures in brain: the cerebrum, the cerebellum, and brain stem. Further, these structures are subdivided into more parts depending on their position in the brain. The cerebrum is the major portion of brain with sulcus and gyrus of folded structure and deep structures too. Corpus callosum connects the right and left hemisphere of brain to communicate. Each hemisphere of the brain is further classified into four regions: frontal, temporal, parietal, occipital lobes. Each lobe deals with different functions. For understanding any disease or doing research or treatment, one should have a depth of knowledge of the brain, its parts, and the functioning of different lobes and regions. Therefore, this chapter will deal with in-depth knowledge of the brain parts, not only anatomically but also their functionality.
