Brain Areas And Their Functions
The brain is divided into areas which are each responsible for different areas of functioning.
The brain can be divided into three basic units: the forebrain, the midbrain and the hindbrain.
These areas are: Occipital lobe, Temporal lobe, Parietal lobe, Frontal lobe.Cerebral cortex, Cerebellum, Hypothalamus,Thalamus,Pituitary gland, Pineal gland, Amygdala, Hippocampas and the Mid- brain.
The image below indicates where the areas are.
Occipital lobe: This is found in the back of the brain. The area is involved with the brain’s ability to recognise objects. It is responsible for our vision.
Temporal lobe: The temporal lobes are found on either side of the brain and just above the ears. The temporal lobes are responsible for hearing, memory, meaning, and language. They also play a role in emotion and learning. The temporal lobes are concerned with interpreting and processing auditory stimuli.
Parietal lobe: The parietal lobes are found behind the frontal lobes, above the temporal lobes, and at the top back of the brain. They are connected with the processing of nerve impulses related to the senses, such as touch, pain, taste, pressure, and temperature. They also have language functions.
Frontal lobe:It is concerned with emotions, reasoning, planning, movement, and parts of speech. It is also involved in purposeful acts such as creativity, judgment, and problem solving, and planning
How Does Your Brain Relate To Hormone Production
Within your thalamus sits a small structure called your hypothalamus. Your hypothalamus is part of your limbic system, which controls your emotions. It sends nerve signals to your pituitary gland. It helps control functions such as:
- Hormone production.
- Sleep and wake cycles.
In your brain, you also have a pineal gland, which secretes the hormone melatonin. Melatonin controls how melanin gives your skin pigment. Melatonin also plays a role in regulating your sleep and wake cycles.
Can A Head Injury Cause A Brain Condition
Injuries can lead to brain damage. When you experience a blow to your head, you may suffer a traumatic brain injury or concussion.
Rarely, severe brain injuries may lead to a condition like epilepsy or dementia. Many people heal from a concussion or brain injury. Repeated head injuries can lead to chronic traumatic encephalopathy , a condition that causes progressively worsening thinking problems.

Symptoms Of Blood Clot In The Brain
If a blood clot occurs in an artery to the brain, stopping the brain from getting the blood and oxygen supply that it needs, this can cause a stroke. Brain tissue starts dying without a constant supply of oxygen, so it is critical to treat the stroke as soon as possible. The longer a stroke remains untreated, the greater the chance that brain cells will die, resulting in permanent stroke-related brain damage.
These debilitating effects can include weakness on one side of the body, difficulty controlling movements, personality or behaviour changes, or problems speaking and understanding.
Symptoms of blood clot in the brain depend on which part of the brain the clot occurs in, but they are the same as the symptoms of a stroke. These can include:
- numbness or weakness in the arm, face or leg
- slurred speech or trouble speaking or understanding others
What Are The Functions Of The Major Parts Of The Brain
The brain has three main parts: the cerebrum , cerebellum and brainstem. Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.

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.

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.

Were going to talk about these five parts, which are key players on the brain team:
Pituitary Gland Controls Growth
The pituitary gland is very small only about the size of a pea! Its job is to produce and release hormones into your body. If your clothes from last year are too small, it’s because your pituitary gland released special hormones that made you grow. This gland is a big player in puberty too. This is the time when boys’ and girls’ bodies go through major changes as they slowly become men and women, all thanks to hormones released by the pituitary gland.
This little gland also plays a role with lots of other hormones, like ones that control the amount of sugars and water in your body.

The human brain is a complex organ that holds the most importance in the entire human body. The objective of this article is to give you an introduction about the parts of the brain and their functions rather than a detailed review of the research that has been done on the brain. The brain weighs just 3 pounds but is responsible for controlling behavior, interpreting the senses and initiating body movement. It is the source of intelligence in our body and is located in a bony shell that is protected by brain fluid. The brain is the reason for all of the qualities we possess that make us human beings.
One of the questions that you could be asking yourself might be “what are the main parts of the brain”. Well, the following is an explanation of the parts of the brain and their functions.

What Are The Regions Of The Brain And Their Functions
The three main regions of the brain are the midbrain, hindbrain and forebrain, which is broken up into additional sections including the frontal lobe, occipital lobe and temporal lobe that control different parts of the body. All of these work together like a well-oiled machine to allow humans to function properly.
What are the three main function of the brain?
The brain has three main parts: It is involved in remembering, problem solving, thinking, and feeling . It also controls movement. The cerebellum sits at the back of your head, under the cerebrum. It controls coordination and balance. The brain stem sits beneath your cerebrum in front of your cerebellum.
What Are The Different Parts Of The Brain
The brain can be divided into 3 main parts:
Cerebrum. The cerebrum is the front part of the brain. It has a right and left hemisphere. Functions of the cerebrum include initiation of movement, coordination of movement, temperature, touch, vision, hearing, speech and language, judgment, reasoning, problem solving, emotions, and learning.
Brainstem. The brainstem is the middle of the brain. It includes the midbrain, the pons, and the medulla. Functions of this part include movement of the eyes and mouth, relaying sensory messages , hunger, respirations, consciousness, cardiac function, body temperature, involuntary muscle movements, sneezing, coughing, vomiting, and swallowing.
Cerebellum. The cerebellum is the back of the brain. It is located at the back of the head. Its function is to coordinate voluntary muscle movements. It also maintains posture, balance, and equilibrium.
Within these 3 main parts, there are these other parts of the brain:

The brain and spine are vital to keep the body alive and functioning. Everything we do depends on the messages that are sent from the brain, along the spinal cord and on to the rest of the body.
Right Brain Left Brain
The cerebrum is divided into two halves: the right and left hemispheres They are joined by a bundle of fibers called the corpus callosum that transmits messages from one side to the other. Each hemisphere controls the opposite side of the body. If a stroke occurs on the right side of the brain, your left arm or leg may be weak or paralyzed.
Not all functions of the hemispheres are shared. In general, the left hemisphere controls speech, comprehension, arithmetic, and writing. The right hemisphere controls creativity, spatial ability, artistic, and musical skills. The left hemisphere is dominant in hand use and language in about 92% of people.

Functions Of Each Part Of Brain
Functions of Each Part of Brain: The brain is that portion of the central nervous system which is contained in the cranium. About 100 billion neurons and 10-50 trillion neuroglia make up the brain, which has a mass of about 1300 g in adults.
The brain and spinal cord develop from ectoderm arranged in a tubular structure called the neural tube. The anterior part of the neural tube expands and constricts into three regions called primary brain vesicles: prosencephalon mesencephalon , and rhombencephalon .
What Are The Main Parts Of The Brain
Your brains structure is complex. It has three main sections:
- Cerebrum: Your cerebrum interprets sights, sounds and touches. It also regulates emotions, reasoning and learning. Your cerebrum makes up about 80% of your brain.
- Cerebellum: Your cerebellum maintains your balance, posture, coordination and fine motor skills. It’s located in the back of your brain.
- Brainstem: Your brainstem regulates many automatic body functions. You dont consciously control these functions, like your heart rate, breathing, sleep and wake cycles, and swallowing. Your brainstem is in the lower part of your brain. It connects the rest of your brain to your spinal cord.

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.
Information Transport And Boundary Assistants
The gyrus and sulcus are what give the brain its wrinkly appearance. The grooves of the brain are known as the sulci, while the bumps are called the gyri. These folds and ridges help increase how much of the cerebral cortex can fit into the skull. They also create boundaries between the different sections of the brain, such as the two hemispheres and four lobes of the cerebrum.

What Is The Corpus Callosum
The cerebrum’s inner core houses the brain’s “white matter.” The major part of the inner core is known as the corpus callosum. The corpus callosum is a thick tract of fibrous nerves that serve as a kind of switchboard enabling the brain’s hemispheres to communicate with one another. Whereas the cerebral cortex is the cerebrum’s outer layer made up of gray matter, and is responsible for thinking, motor function and information processing the corpus callosum is the cerebrum’s inner core, made up of white matter, with four parts of nerve tracts connecting to different parts of the hemispheres.

The corpus callosum’s nerve fibers are coated with myelin. This fatty substance helps increase the transmission of information between the next part of the cerebrum: the two hemispheres.
Which Nerves Send Signals To And From Your Brain
Your brain contains several types of nerves. Nerves carry messages by sending electrical impulses back and forth between your brain, organs and muscles. The nerves in your brain are called cranial nerves.You have 12 pairs of cranial nerves from the brain to parts of your head and face. These nerves are responsible for specific sensations, such as hearing, taste or sight. White matter is the fiber bundles that connect brain cells. There are numerous white matter tracts that connect one area of your brain to another, as well as structures deep in your brain. These white matter tracts can also travel to your brainstem and spinal cord so that information can be relayed from your brain to communicate with the rest of your body and information from your body can travel to your brain.

What Are The 4 Lobes Of The Brain
Database Center for Life Sciences/Wikimedia Commons
The cerebrum’s left and right hemispheres are each divided into four lobes: the frontal, parietal, occipital and temporal lobes. The lobes generally handle different functions, but much like the hemispheres, the lobes don’t function alone. The lobes are separated from each other by depressions in the cortex known as sulcus and are protected by the skull with bones named after their corresponding lobes.
Cancer Research UK/Wikimedia Commons
The frontal lobe is located in the front of the brain, running from your forehead to your ears. It is responsible for problem-solving and planning, thought, behavior, speech, memory and movement. The frontal lobe is separated from the parietal lobe by the central sulcus and is protected by a singular frontal skull bone.
The parietal lobe picks up where the frontal lobe ends and goes until the mid-back part of the brain . It is responsible for processing information from the senses , as well as language interpretation and spatial perception. It is separated from the other lobes on all four sides: from the frontal lobe by central sulcus from the opposite hemisphere by the longitudinal fissure from the occipital lobe by parieto-occipital sulcus and from the temporal lobe below by a depression known as the lateral sulcus, or lateral fissure. Because each hemisphere has a parietal lobe, there are two parietal skull bonesone on the external side of each hemisphere.
Major Structures And Functions Of The Brain
Outside the specialized world of neuroanatomy and for most of the uses of daily life, the brain is more or less an abstract entity. We do not experience our brain as an assembly of physical structures if we envision it at all, we are likely to see it as a large, rounded walnut, grayish in color.
This schematic image refers mainly to the cerebral cortex, the outermost layer that overlies most of the other brain structures like a fantastically wrinkled tissue wrapped around an orange. The preponderance of the cerebral cortex is actually a recent development in the course of evolution. The cortex contains the physical structures responsible for most of what we call brainwork : cognition, mental imagery, the highly sophisticated processing of visual information, and the ability to produce and understand language. But underneath this layer reside many other specialized structures that are essential for movement, consciousness, sexuality, the action of our five senses, and moreall equally valuable to human existence. Indeed, in strictly biological terms, these structures can claim priority over the cere-
