What Part Of The Brain Controls Speech And Motor Skills
frontal lobesThe frontal lobes are the largest of the four lobes responsible for many different functions. These include motor skills such as voluntary movement, speech, intellectual and behavioral functions.
Which part of the brain controls the involuntary activities?
brain stemThe brain stem is an automatic control center for many such important involuntary actions of the body. And, it is a pathway for impulses travelling back and forth between the body and the rest of the brain.
What Part Of The Brain Controls Involuntary Breathing
The brain stem sits beneath your cerebrum in front of your cerebellum. It connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate and blood pressure.
Why I get angry so quickly?
Some common anger triggers include: personal problems, such as missing a promotion at work or relationship difficulties. a problem caused by another person such as cancelling plans. an event like bad traffic or getting in a car accident.
What Are The Parts Of The Nervous System
The nervous system is made up of the central nervous system and the peripheral nervous system:
- The brain and the spinal cord are the central nervous system.
- The nerves that go through the whole body make up the peripheral nervous system.
The human brain is incredibly compact, weighing just 3 pounds. It has many folds and grooves, though. These give it the added surface area needed for storing the body’s important information.
The spinal cord is a long bundle of nerve tissue about 18 inches long and 1/2-inch thick. It extends from the lower part of the brain down through spine. Along the way, nerves branch out to the entire body.
The brain and the spinal cord are protected by bone: the brain by the bones of the skull, and the spinal cord by a set of ring-shaped bones called vertebrae. They’re both cushioned by layers of membranes called meninges and a special fluid called cerebrospinal fluid. This fluid helps protect the nerve tissue, keep it healthy, and remove waste products.

How is movement and sensation controlled in the brain?
For example, movement and sensation on one side of the body are controlled by the hemisphere on the opposite side. Other functions are performed mainly by one hemisphere, which is said to be dominant for that function, and the other hemisphere is said to be nondominant.
How Many Brain Cells Does A Human Have
For many years, scientists thought the human brain had 100 billion nerve cells . Today, we know the actual number is closer to 86 billion.
Your brain contains two types of cells:
- Neurons send and receive electric nerve signals.
- Glial cells help maintain your brain, form myelin and provide nutrition to your brain.

Chemical And Electrical Signals
The actual signals transmitted throughout the brain come in two forms, electrical and chemical. The two forms are interdependent and meet at the synapse, where chemical substances can alter the electrical conditions within and outside the cell membrane.
A nerve cell at rest holds a slight negative charge with respect to the exterior the cell membrane is said to be polarized. The negative charge, the resting potential of the membrane, arises from a very slight excess of negatively charged molecules inside the cell.
A membrane at rest is more or less impermeable to positively charged sodium ions , but when stimulated it is transiently open to their passage. The Na+ ions thus flow in, attracted by the negative charge inside, and the membrane temporarily reverses its polarity, with a higher positive charge inside than out. This stage lasts less than a millisecond, and then the sodium channels close again. Potassium channels open, and K+ ions move out through the membrane, reversing the flow of positively charged ions. Over the next 3 milliseconds, the membrane becomes slightly hyperpolarized, with a charge of about -80 mV, and then returns to its resting potential. During this time the sodium channels remain closed the membrane is in a refractory phase.
New Research Sheds Light On The Brains Computational Function
The human brains function is remarkable, driving all aspects of our creativity and thoughts. However, the neocortex, a region of the human brain responsible for these cognitive functions, has a similar overall structure to other mammals.
Researchers from The University of Queensland , The Mater Hospital, and the Royal Brisbane and Womens Hospital have shown that changes in the structure and function of our neurons may be the cause of the human brains increased processing power.
They recently published their findings in the journal Cell Reports.
Professor Stephen Williams of UQs Queensland Brain Institute explained that his team has researched the electrical properties of human neocortical pyramidal neurons embedded in their neuronal networks.
To study human neurons, we prepared live tissue slices from small blocks of the human neocortex collected from patients who were undergoing neurosurgery for the alleviation of refractory epilepsy or the removal of brain tumors at the two hospitals, Professor Williams said.
Dr. Helen Gooch, a QBI postdoctoral fellow and co-author of the study, stated that the team discovered that the architecture of human neocortical pyramidal neurons dendritic treesthe branch-like extensions that carry electrical signalswas larger and more complex than that of other mammals, such as rodents.
The translation of such discoveries paves the way for a better understanding of how the electrical activity of the human brain is disturbed in disease.

The Cerebellum’s Balancing Act
Next up is the cerebellum. The cerebellum is at the back of the brain, below the cerebrum. It’s a lot smaller than the cerebrum. But it’s a very important part of the brain. It controls balance, movement, and coordination .
Because of your cerebellum, you can stand upright, keep your balance, and move around. Think about a surfer riding the waves on his board. What does he need most to stay balanced? The best surfboard? The coolest wetsuit? Nope he needs his cerebellum!
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.

How Does Touch Affect Different Parts Of The Brain
From what can be seen so far, touch impacts many parts of the brain and multiple functions. Our thinking, feeling, sensory and motor systems are all affected by touch as well as parts of the brain involved in learning new movements.
Why is the sense of touch important to the human body?
Our skin acts as the protective barrier between our internal body systems and the outside world. Its not only the bodys largest sensory organ, its the largest organ period! The skins sense of touch is what gives our brains a wealth of information about the natural environment, including temperature, humidity, and air pressure.

The Cerebrum: Front Part Of The Brain
The largest part of the brain, located in the front, is called the cerebrum. The cerebrum is responsible for:
The cerebrum is made up of the right and left cerebral hemispheres. The hemispheres are connected at the bottom and have a deep groove running between them. In general, the right cerebral hemisphere controls the left side of the body, and the left cerebral hemisphere controls the right. The right side is involved with creativity and artistic abilities. The left side is important for logic and rational thinking.
The cerebral hemispheres are divided into lobes . Each lobe is responsible for a variety of bodily functions. Frontal lobes are involved with personality, speech, and motor development. Temporal lobes are responsible for memory, language and speech function. Parietal lobes are involved with sensation, while the occipital lobes are the primary vision centers.
The surface of the cerebrum appears wrinkled and is made up of deep grooves and bumps or folds . The outer part of the cerebrum is called gray matter and contains nerve cells. The inner part is called white matter and contains connections of nerves.
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

What Is The Brain
Your brain is an essential organ. All of your emotions, sensations, aspirations and everything that makes you uniquely individual come from your brain. This complex organ has many functions. It receives, processes and interprets information. Your brain also stores memories and controls your movements.
Your brain is one component of your central nervous system . It connects to your spinal cord, the other part of your CNS.
Brain Stem Keeps You Breathing And More
Another brain part that’s small but mighty is the brain stem. The brain stem sits beneath the cerebrum and in front of the cerebellum. It connects the rest of the brain to the spinal cord, which runs down your neck and back. The brain stem is in charge of all the functions your body needs to stay alive, like breathing air, digesting food, and circulating blood.
Part of the brain stem’s job is to control your involuntary muscles the ones that work automatically, without you even thinking about it. There are involuntary muscles in the heart and stomach, and it’s the brain stem that tells your heart to pump more blood when you’re biking or your stomach to start digesting your lunch. The brain stem also sorts through the millions of messages that the brain and the rest of the body send back and forth. Whew! It’s a big job being the brain’s secretary!

What Are The Four Nuclei Of The Cerebellum
As the three lobes take in information from the cerebrum, spinal cord and body, the cerebellum also has a way of sending out information. This is done through what are called nucleia bundle or neurons embedded deep in the cerebellum’s white matter.
Rounding out cerebellum’s composition are the four nuclei that pass information between the cerebrum and the body. These nuclei are: dentate, emboliform, globose, and fastcgi. They receive on the body and give information from the cerebellum through Purkinje cells and mossy fibers.

The final section of the brain is a mass of tissue and nerves called the brain stem. Located underneath the cerebrum and cerebellum, the brain stem connects the brain to the spinal cord. All information that goes from the brain to the body , must pass through the brain stem to reach its destination. The brain stem accounts for the remaining 5% of the brain’s mass, and is , the oldest part of the brain. The brain stem is responsible for regulating the heart and lungs, communications between the brain and the peripheral nervous system , our sleep cycle, and coordinating reflexes.
The brain stem plugs the brain into the rest of the body through the spinal cord .
Multisystem Inflammatory Syndrome In Adults
Multisystem inflammatory syndrome in children is a rare but severe condition in children and adolescents infected with SARS-CoV-2, the virus that causes COVID-19. Since June 2020, there have been several reports of a similar multisystem inflammatory syndrome in adults . CDC a number of cases that fit the description of MIS-A. This report shows the way the syndrome appears in adults may be more complicated than in children.
Like children, adults who have been infected with the virus that causes COVID-19 can develop symptoms of MIS-A days to weeks after getting sick. MIS-A is a condition where problems can occur in different parts of the body like the heart, gastrointestinal tract, skin, or brain.

Brain Conditions When The Brains Structure Is Damaged
Your brain is one of the most complex organs in the human, and if one of the brains structures is damaged, it could lead to a brain condition.
For example, if your Brocas area is damaged, you may have trouble moving your tongue, and your speech may be slow and poorly articulated. Other conditions that could affect the brain include:
Brain aneurysm: When an artery in the brain swells, it could lead to a brain aneurysm. If the aneurysm ruptures, it could cause a stroke.
Brain tumor: When any tissue in your brain starts growing abnormally, it could be symptoms of benign or malignant cancer.
Intracerebral hemorrhage: Bleeding inside the brain can cause difficulty speaking or difficulty walking.
Concussion: When theres a heavy blow to the head, you may experience a concussion and temporarily lose brain function.
Cerebral edema: Electrolyte imbalance in the brain could lead to swelling of the brain tissue.
Glioblastoma: Glioblastoma is a brain tumor that develops very rapidly and creates pressure on the brain.
Pro tip: Glioblastoma is usually aggressive and could be very difficult to cure.
Meningitis: When the lining around the brain or spinal cord becomes inflamed from an infection, you may have meningitis. Other symptoms associated with meningitis include headache, fever, sleepiness, neck pain, and stiff neck.
Traumatic brain injury: A severe head injury could lead to permanent brain damage. Other symptoms include mental impairment and personality and mood changes.

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.
