Feb 20, 2024 · The three main parts of the brain are the cerebrum, cerebellum, and brainstem. 1. Cerebrum. Location: The cerebellum occupies the upper part of the cranial cavity and is the largest part of the human brain. Functions: It’s responsible for higher brain functions, including thought, action, emotion, and interpretation of sensory data.

The cerebrum is divided into two halves: the right and left hemispheres(Fig. 2). The left hemisphere controls the right half of the body, and the right hemisphere controls the left half. The two hemispheres are connected by a thick band of neural fibers known as the corpus callosum, consisting of about 200 million axons. The corpus callosum allows ...
Each cerebral hemisphere can be subdivided into four lobes, each associated with different functions. Figure 3.The cerebrum is divided into four lobes: frontal, parietal, occipital, and temporal.
The surface of the cerebrum is called the cerebral cortex and has a wrinkled appearance, consisting of bulges, also known as gyri, and deep furrows, known as sulci(Figure 8). A gyrus (plural: gyri) is the name given to the bumps and ridges on the cerebral cortex (the outermost layer of the brain). A sulcus (plural: sulci) is another name for a groo...
Within the brain, there are fluid-filled interconnected cavities called ventricles, which are extensions of the spinal cord. These are filled with a substance called cerebrospinal fluid, which is a clear and colorless liquid. The ventricles produce cerebrospinal fluid and transport and remove this fluid. The ventricles do not have a unique function...
Neurons are the nerve cellsof the central nervous system that transmit information through electrochemical signals throughout the body. Neurons contain a soma, a cell body from which the axon extends. Axons are nerve fibers that are the longest part of the neuron, which conduct electrical impulses away from the soma. There are dendrites at the end ...

1 day ago · The lateral view of the brain is like a map of an alien world, familiar yet mysterious. It’s the perspective most commonly depicted in textbooks and medical illustrations, showing the brain as if we’re looking at it from the side. This view is crucial for understanding the brain’s overall structure and the relationships between its ...
