Study And Understand The Structure Of Brain With The Brain Diagram

brain diagram

The human central nervous system consists of the brain and the spinal cord. The brain is the main controlling unit of the human body and is the most complicated part to study. It is the mass of nerve tissue that is present at the anterior end of the organism. The human brain weighs around 1.4 kg and is made up of billions of cells termed neurons. Neurons are the functional and basic unit of the brain. Neurons meet each other at junctions called synapses. They enable chemical and electrical messages to be transmitted from neuron to neuron and then to the brain. With this transmission process, our brain can perform learning, thought formation, cognitive activities, etc. The basic human brain diagram is divided into three parts- the cerebrum, cerebellum, and brainstem. Each distinct part plays a specific role that allows the human body to function properly in a coordinated manner. 

Division Of Brain Diagram With Their Functions

The cerebrum is the largest part of the human brain. All the functions like interpreting touch, vision, hear, reasoning emotions, and the cerebrum performs movement control. The cerebrum is further divided into two halves in the brain diagram: the right and the left hemispheres. The right hemisphere controls the left side of the body, while the left hemisphere controls the right side of the body. These hemispheres are connected by a bundle of fibers called the corpus callosum. This corpus callosum Helps to transmit the messages from one hemisphere to another. The left hemisphere controls speech, arithmetic, comprehension, and writing. And the right hemisphere controls spatial ability, creativity, and musical skills, etc. Each hemisphere is divided further into four lobes by distinct fissures: frontal, temporal, parietal, and occipital lobe. Each lobe has areas that serve different and specific functions. 


The cerebellum is the part of the 3d brain diagram which is located under the cerebrum. It is the largest part of the hindbrain. Its main function is to maintain posture, balance and coordinate the movements, etc. It performs cognitive functions such as language, attenuation, and response to pleasure, sorrow, etc. When the cerebellum receives the motor information from the cerebral cortex and the musculoskeletal structures, it coordinates the signals to maintain complete balance and posture during motion. 


It is the connection or the relay center between the cerebrum, cerebellum, and spinal cord. The body’s involuntary functions like breathing, wake, and sleep cycles, digestion, sneezing, vomiting, coughing and swallowing, etc., are performed by the brainstem of the brain diagram. The brainstem is further divided into four distinct sections to study the brain diagram more easily. They are the diencephalon (the most superior portion), midbrain, pons, and the medulla oblongata.


The human brain is quite a complicated part of the human body. Brain diagrams have been divided into different parts to make the study of the brain easy and less complicated.
