The Three Main Parts Of Your Brain by Dr. Russ Harris

Since its creation by Congress in 1950, the NINDS has grown to become the leading supporter of neurological research in the United States. Most research funded by the NINDS is conducted by scientists in public and private institutions such as universities, medical schools, and hospitals. Government scientists also conduct a wide array of neurological research in the more than 20 laboratories and branches of the NINDS itself. This research ranges from studies on the structure and function of single brain cells to tests of new diagnostic tools and treatments for those with neurological disorders.

    The Little Brain At The Back Of The Head

    While autonomic and endocrine functions are being maintained by structures deep inside the brain, another specialized area is sorting and processing the signals required to maintain balance and posture and to carry out coordinated movement. The cerebellum is actually a derived form of the hindbrainas suggested by its position at the back of the head, partly tucked under the cerebral hemispheres. In humans, with our almost unlimited repertoire of movement, the cerebellum is accordingly large in fact, it is the second-largest portion of the brain, exceeded only by the cerebral cortex. Its great surface area is accommodated within the skull by elaborate folding, which gives it an irregular, pleated look. In relative terms, the cerebellum is actually largest in the brain of birds, where it is responsible for the constant streams of information between brain and body that are required for flight.

    The three major parts of the brain are:

    • Cerebrum: It the largest part of the brain. It is made up of the right hemispheres and left hemispheres. It is responsible for voluntary activity, sensory functions, and neural functions.
    • Cerebellum: It the region found below the cerebrum and back the brainstem, the function of the cerebellum is to regulate the motor and voluntary movements.
    • brainstem: It controls the basic function of the body such as heart rate, breathing, blood pressure, swallowing, and consciousness.

    The Lobes Of The Brain

    The brain is separated into four lobes: the frontal, temporal, occipital, and parietal lobes.

    Lobes of the brain: The brain is divided into four lobes, each of which is associated with different types of mental processes. Clockwise from left: The frontal lobe is in blue at the front, the parietal lobe in yellow at the top, the occipital lobe in red at the back, and the temporal lobe in green on the bottom.

    The Cerebellum: Back Of The Brain

    Behind the cerebrum at the back of the head lies the cerebellum. In Latin, cerebellum means little brain, but the cerebellum actually contains more nerve cells than both hemispheres combined. The cerebellum is primarily a movement control center, responsible for:

    • Voluntary muscle movements
    • Fine motor skills
    • Maintaining balance, posture & equilibrium

    Unlike the cerebrum, the left cerebellum controls the left side of the body, and the right cerebellum controls the right side of the body.

    The anterior lobe and the vermis together are known as the spinocerebellum. The spinocerebellum helps regulate muscle tone and body movement. It’s also responsible for our sense of our body’s position in relation to our surroundings, and in relation to other parts of our body . This area receives input from our spinal cord, auditory and visual systems.

    A Sorting Station: The Thalamus Mediates Sensory Data And Relays Signals To The Conscious Brain

    The Triune Brain

    The diencephalon is a region of the forebrain, connected to both the midbrain and the cerebrum. The thalamus forms most of the diencephalon. It consists of two symmetrical egg-shaped masses, with neurons that radiate out through the cerebral cortex. Sensory data floods into the thalamus from the brain stem, along with emotional, visceral, and other information from different areas of the brain. The thalamus relays these messages to the appropriate areas of the cerebral cortex. It determines which signals require conscious awareness, and which should be available for learning and memory.

  • Lobes Of The Brain And What They Control

    Each brain hemisphere has four sections, called lobes: frontal, parietal, temporal and occipital. Each lobe controls specific functions.

    • Frontal lobe. The largest lobe of the brain, located in the front of the head, the frontal lobe is involved in personality characteristics, decision-making and movement. Recognition of smell usually involves parts of the frontal lobe. The frontal lobe contains Brocas area, which is associated with speech ability.
    • Parietal lobe. The middle part of the brain, the parietal lobe helps a person identify objects and understand spatial relationships . The parietal lobe is also involved in interpreting pain and touch in the body. The parietal lobe houses Wernickes area, which helps the brain understand spoken language.
    • Occipital lobe. The occipital lobe is the back part of the brain that is involved with vision.
    • Temporal lobe. The sides of the brain, temporal lobes are involved in short-term memory, speech, musical rhythm and some degree of smell recognition.

    Major Parts of Human Brain

    Give any three major functions of a human brain or what are the major functions of the human brain?

    The function of a human brain are:

    • Brain stores information so that behavior can be modifies according to the past experience.
    • Brain correlates he various stimuli from various sense organs and produce response.
    • Brain responds to the impulses by sending its own instructions through motor nerves to the effectors.

    The brain controls our thoughts, memory and speech, movement arms and legs, and the function of many organs within our body. The central nervous system is composed of the brain and spinal cord.

    Some of the major functions of the brain that it carries out day to day are :

    movement control, sensory functions, regulation function, language function, connecting both side of the body and coordination between them, emotion, memories and cognition functions.

    Neurons And Glial Cells

    The human brain has about 80-100 billion neurons, and roughly the same of glial cells. Neurons and glial cells help coordinate and transport signals within the human nervous system. While neurons communicate and receive information with cells, glial cells protect and support neurons in completing their mission.

    Food And Waste Transport

    The cerebrospinal fluid is responsible for bringing in nutrients and removing waste in the brain and spinal cord. It is found in the meninges layers and is moved through the brain by ventricles.

    The brain’s four main ventricles help the cerebrospinal fluid nourish and cleanse the brain. They also cushion the brain from injury.

    Of all the human body systems, the nervous system is the most complicated system in the body. The brain is the central part of the nervous system. It is an intriguing organ, that has been studied right from the time it develops in the fetus. The human brain weighs about 1.5 kg in adults. The cerebrum, which forms the bulk of this organ, is divided into two hemispheres, the right hemisphere and the left hemisphere.

    There are many ways of dividing the brain for studying its various aspects. However, it is conventionally divided into three parts: the forebrain, the midbrain and the hindbrain. The brain also contains four interconnected cavities called ventricles, which contain cerebrospinal fluid. We will study the diagram of the brain and its functions in this article, along with a detailed study of the brain anatomy.

      The brain is a complex organ that acts as the control center of the body. As a component of the central nervous system, the brain sends, receives, processes, and directs sensory information. The brain is split into left and right hemispheres by a band of fibers called the corpus callosum. There are three major divisions of the brain, with each division performing specific functions. The major divisions of the brain are the forebrain , midbrain , and hindbrain .

      The Cerebellum’s Inner And Outer Layers

      Like the cerebrum, the cerebellum has two layers: one inner and one outer. The outer layer is called the cerebellar cortex. Like the cerebral cortex, it is full of gray matter. Functions such as movement, motor learning, balance and posture happen here.

      Underneath the cortex lies the cerebellum’s white matter. Called “arbor vitae” for its appearance, the cerebellum’s white matter contains cerebellar nuclei. These neurons are vital because they relay information between the cerebral cortex and the peripheral nervous system to assist in learning and cognitive functions, motor control, balance and coordination.

      In Conclusion: Brain Anatomy

      The human brain is an incredibly complex, hardworking organ. As one-half of the human nervous system, the brain structure oversees nearly all of the body’s operations, including how we move, think, feel and understand ourselves and the world around us. And knowing all this brain anatomy is important. From the cerebrum, cerebellum and the brain stem, to all the parts in between: this three-pound organ is what makes us humans, well, human.

      How The Lobes Of The Brain Interact

      The lobes of the brain are not separated from one another by bones or other barriers, and must constantly interact with one another to process and synthesize information. All of the lobes are either physically connected to one another, or connect via nerve signals, and researchers sometimes debate the precise point at which one lobe begins and another ends.

      The brain is divided into left and right hemispheres, and each lobe crosses both hemispheres. Thus doctors and researchers sometimes refer to two distinct lobesthe left frontal lobe and right frontal lobe, for example.

      Main Parts Of The 3 Pound Human Brain

      The brain is a powerful and vital organ that is essential tobeing alive. With that said, it would not hurt to have knowledge of the mainparts of the brain and their functions. Basically, the brain has 3 parts: the cerebrum, the cerebellum and the brainstem. Each of these parts provides different functions for the brain, and wecannot survive without them.

      1. Cerebrum: also called cortex is by far the largestportion of the brain, and weighs about two pounds. For the record, the entirebrain weighs three pounds. The cerebrum is home to billions and billions ofneurons. These neurons control virtually everything we do. It controls ourmovements, thoughts and even our senses. Since the cerebrum has so many functions,if its damaged, there are many different consequences.

      The cerebrum consists of four different lobes that controlall of our movements. The four lobes include: the frontal lobe, parietal lobe,temporal lobe and the occipital lobe. The frontal lobe controls our emotions,judging and planning skills. The parietal lobe controls our senses such astaste, temperature and pain. The temporal lobe controls our auditory processesand hearing. The occipital lobe controls our vision.

      Lastly, the cerebrum consists of two layers: the cerebralcortex, which controls our coordination and personality, and the white matterof the brain, which allows the brain to communicate.

      What Are The Layers Of The Cerebrum

      The cerebrum has two layers: one inner and one outer. The outer layer is known as the cerebral cortex . Most times, whenever you see photos of the brain, you are looking at the cerebral cortex. This area houses the brain’s “gray matter,” and is considered the “seat” of human consciousness. Higher brain functions such as thinking, reasoning, planning, emotion, memory, the processing of sensory information and speech all happen in the cerebral cortex. In other words, the cerebral cortex is what sets humans apart from other species.

      The cerebral cortex is referred to as “gray matter,” due to its color and is responsible for several vital functions, such as those listed above.
