Essay About The Brain

The Importance Of The Human Brain
The human brain is the direction for the nervous system. The brain tells the human what to do such
as, it receives the input from the sensory organs, and then sends output to the muscles (Lewis, 2016).
The human brain has responsibilities in the body just like the other organs, but has its own duties to
maintain (Lewis, 2016). However, the human brain makes up 2 percent of the human body weight
(Lewis, 2016). The cerebrum is the largest part of the human brain, and is branched into two
different hemispheres (Lewis, 2016). Individuals also call the two the left and the right hemisphere.
The brainstem is located underneath, and the cerebellum sits behind it (Lewis, 2016). The human
brain is also divided into three different sections which is known as the forebrain, midbrain, and the
hindbrain (Lewis, 2016). Each of the sections have something in common which is fluid–filled
cavities called ventricles (Lewis, 2016). There are still more pathways in the future that need to be
explored to clearly under the human brain.
Understanding the Human Brain There are still different pathways to be explored in our
understanding of the human brain due to there is different studies that come as the years progress.
One of the components that will still be open to the question is the several factors that affect the
human brain that causes mental illnesses. The defining of the human brain is complication, and how
the complication comes from the wide range of numerous factors that result in a

Subtopics About The Brain
Did you know that your brain weighs around 3 pounds and it's 2% of your body's weight? The
brain is an organ that collects data. The brain is separated into halves into left and right
hemispheres. It can collect data from sensory organs and nerve cells. In this essay, you'll learn about
3 subtopics about the brain: how does the brain work, what are the lobes of the brain, and what do
the left and right hemispheres do?
There are many ways how the brain works. The main way is the brain collects data from sensory
organs and nerve cells, but that's not all. The main structure of the brain is the cerebrum. There are
two parts: the left hemisphere and the right hemisphere. Two structures called the thalamus and the
hypothalamus deal with pain, hormones, and sleep. The hormones controls simple emotions. And
the farthest structure from the center of the brain is the cerebral cortex, which it deals with big tasks,
such as language, memory, thoughts, and emotions....show more content...
The 4 lobes are the Frontal Lobe, Parietal Lobe, Temporal Lobe, and Occiptal Lobe. These 4 lobes
have jobs, but you'll learn first where they're located. The Frontal Lobe is located at the front of
the brain. The Parietal Lobe is located at the top of the brain. The Temporal Lobe is located at
both sides of the brain. And finally, the Occiptal Lobe is located at the back of the brain. Now,
you'll learn about the jobs of the 4 lobes.The Frontal Lobe's job is on planning, reasoning, a part of
speech, movement, and solving problems. The Temporal Lobe is specialized to hear and remember
your memories. The Occiptal Lobe's shift is to sight things and vision. And The Parietal Lobe's work
is on touching, pressure, temperature, and

Persuasive Essay On How To Affect The Brain
Your brain is an organ that needs to be used in order to maintain its peak efficiency. Just like any
other organ in the body, the brain will decline with age and lack of use. Similar to a computer, your
brain is the command center for your entire body. The brain has over one hundred billion nerve cells
that are interconnected to one another. Mentally stimulating your brain on a consistent basis will
protect you from losing vital cognitive abilities. You should think of exercising your brain like
physically exercising the rest of your body. Most age related memory loss is brought about by lack
of mental activity and stimulation of the brain. The brain is continually growing new neurons so it
is always possible to improve your brain function. There are various techniques that you can use to
improve your brain function and prevent cognitive decline. You can improve your brain and
improve your sense of alertness and well–being.
Physical Exercise: When you exercise you are actually helping your brain as well. Many people fail
to make this connection. They may say that they feel better and happier after a workout. This is
because exercise stimulates the nervous system. There have been many studies conducted showing
how exercise before class helps students to be calmer and more focused in the classroom. Exercise
stimulates serotonin which helps you to feel more peaceful. Many people will try to exercise in the
morning before work in order to feel more alert and focused during

The Importance Of The Human Brain
The brain is such an amazing organ. The function of the brain is to receive information from other
parts of the body, understand the information, and the figure out how to respond to the situation. The
brain is responsible for such important things such as memory, body movements, the senses, and
pretty much everything else. The average female brain weighs about 2.7lbs, and the average male
brain weighs about 3lbs. The brain is also one of the fattest organs in the body. A little fun fact
about the brain is that all of the blood vessels, located in just the brain, can stretch out to be
100,000 miles long. The human brain is the largest brain compared to all other living things around
the same body size, and it makes up about 2% of the body weight.
The nervous system is an important part of the brain, and its purpose is to send messages to the
brain. Which is divided into the central and peripheral systems. The central is composed of the
brain. The peripheral is made of the spinal cord.
There are three main part of the brain. The forebrain, midbrain, and hindbrain. The forebrain is
located in the anterior part of the brain in the cerebral hemisphere. It consists of the thalamus,
hypothalamus, and the subthalamus. (Britannica, encyclopedia britannica, 2017) The midbrain is
located in the brain stem. It is responsible in aiding with vision, hearing, and motor control.
(Britannica, Midbrain, 2017) Lastly, the hindbrain. The hindbrain consists of the medulla oblongata
(breathing

The Brain And Its Anatomy
Our brains have the enough power to make all of the many different parts of our body function the
way it should. It can make our body do involuntary actions that constantly keep us alive and healthy,
and we don't even realize all of the things that it is capable of. As Nicolaus Steno once said, "The
brain, the masterpiece of creation, is almost unknown to us" (web.stanford.edu, 2014). The brain and
its anatomy were first studied by the Egyptians in 1700 B.C., and ever since then, its immeasurable
power has been continuously astonishing us with new and amazing discoveries of previously
unknown capabilities (faculty.washington.edu, 2014). The first person to dissect the brain to study
relationships between the brain and optic nerves was...show more content...
And, since this experiment is about how hand eye dominance affects the hand eye coordination used
when shooting a basketball, the occipital lobe is one of the most important parts of the brain in
regards to this experiment.
Everyone knows that the typical human being has a dominant hand.The only case in which a
person does not have a dominant hand is if that person can use their right and left hand equally
well. In this case this person is ambidextrous. But, the typical human also has a dominant foot, ear,
side of the brain, and eye. (web.stanford.edu, 2014) Eye dominance, or eyedness, is the tendency to
prefer visual input from one eye to the other. This is similar to left or right handedness. For people
who have anisometropic myopia, a different amount of nearsightedness in each eye, the eye with
more myopia or nearsightedness is the dominant eye (web.stanford.edu, 2014). The easiest way to
test your eyedness is to create a small triangle with your hands, with your thumbs as the base of the
triangle and your left hand's fingers overlapping your right hand's fingers , and center it around an
object, such as a doorknob, about 5–10 feet away with both eyes open. Then, close your left eye. If
you can still see the object with your right eye opened, then your right eye is your dominant eye. If
the object moves out of your view, then close your right eye. You will most likely see the object
with your left eye, in which case your dominant eye is your left eye

Questions about the human brain have been a topic that many scientists and philosophers have
focused on for centuries, trying to understand and learn the way it truly works . Over these past ten
years, scientists have been the most successful in brain development, due to a large amount of
research on this fascinating subject. Different ways to keep the brain stimulated have been an
important topic while learning about the brain over the years due to its large importance. The
human brain needs to be worked everyday in order for it to maintain a healthy state. Every time a
new piece of information is taken in, different areas of your brain are put to use. It has been found
that the more often stimulation of the brain occurs it enables the brain to be able to perform better
on a daily basis and for longer periods of time....show more content...
This is expected because chewing gum is suspicioned to be an accurate way to stimulate the brain
which helps students increase intellectual performance by their ability to concentrate at a faster rate.
Chewing gum causes stimulation of the brain because it improves blood flows, increasing arousal
towards the brain ultimately innervating the jaw. The innervation begins with the repetitive chewing
motion caused by the gum, which triggers the trigeminal nerve that works the jaw muscles and lets
blood flow to the brain supplying it with nutrients, improving its functions. It's important to
recognize certain controls throughout this experiment such as gender, gum flavour, and
environment. None of the mentioned factors may have changed

Advantages And Disadvantages Of The Brain
Long ago, to understand the brain, its structural features and functions the only time this was
possible were through a post mortem examination. Due to technological advances, this has become
easier through various brain imagining techniques; the Magnetic Resonance Imaging (MRI) and the
Positron Emission Tomography (PET). Thus, for the purpose of this essay, these two methods will
be discussed as well as their advantages and disadvantages.
The brain is a portion of the central nervous system, which functions as a primary receiver,
organizer, and distributor of information for the body (www.medicinenet.com). The first method to
be discussed is the Magnetic Resonance Imagining. It uses a large magnet, radio waves, and a
computer to create a detailed cross–sectional image of the patient's internal organs and...show more

The cognitive functions are distributed across the hemispheres but there are specific processes that
are specialized to one hemisphere. Localization function which is on the left is known for its
dominancy for language (www.indiana.edu). This concept traces back to faculty psychology, which
was developed by Franz Gall and stated that different abilities such as reading were independent and
autonomous function carried out in certain parts of the brain. Phrenology was developed as a way of
further understanding the brain and this is the belief that certain mental faculties and character traits
are indicated by the size of the skull (Galotti, 2008).
Broca discussed that injury to the left frontal lobe can cause inability to produce many words or
speak fluently. This is known as Aphasia; disruption of expressive language. A second language
centre was found which focuses on the control of language understanding rather than language
production. This is located in the posterior region of the temporal lobe. Injury to this region of the
brain can lead to an individual speaking gibberish (Galotti,

Essay about Drugs Affect on Brain
Abstract Drugs some use them to escape pain, others use them for pleasure, and some use them to
just fit in. Either way drugs are a harmful substance that may seriously affect the body. Drugs mess
with the brain in ways that we couldn't even imagine. From destroying brain cells that help with
critical thinking to destroying cells that give us the ability to feel pleasure. Drugs take the place
of our natural body functions of the body. They fool receptors of the body and make it to where
our bodies produce less of what we need. Over a period of time this may produce very severe
consequences on the body. With all the risks involved with drugs it's a wonder why some people use
them.
Introduction The human brain is the...show more content...
In addition, the limbic system is responsible for our perception of other emotions, both positive and
negative, which explains the mood altering properties of many drugs. The cerebral cortex is divided
into areas that control specific functions. Different areas process information from our senses,
enabling us to see, feel, hear, and taste. The front part of the cortex, the frontal cortex or forebrain, is
the thinking center of the brain, it powers our ability to think, plan, solve problems, and make
decisions.
How drugs work in the brain Drugs are chemicals they work in the brain by tapping into the brain's
communication system and interfering with the way nerve cells normally send, receive, and process
information. Some drugs, such as marijuana and heroin, can activate neurons because their chemical
structure mimics that of a natural neurotransmitter. This fools receptors and allows the drugs to lock
onto and activate the nerve cells. Although these drugs mimic brain chemicals, they don't activate
nerve cells in the same way as a natural neurotransmitter, and they lead to abnormal messages being
transmitted through the network.
Other drugs, such as amphetamine or cocaine, can cause the nerve cells to release abnormally large
amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals. This
disruption produces

The Human Brain Essay
The Human Brain
The human being is considered to be the ultimate form of life on the earth. This is not because the
human body is strong and agile. Many other animals posses skills much superior to humans and are
able to perform feats humans can only dream of. The one thing that distinguishes humans from all of
the other organisms on this planet is the brain. The brain is the site that controls the human body.
However, unlike in animals, in man, the brain is also the site of the mind. The mind gives humans
superiority over other creatures. It provides humans with the ability to reason, to feel and to adapt.
Because of this, man has achieved so much, and has also realized that much more is still ahead.

This increase in knowledge is partly due to the recent advances in nuclear medicine. Although X–ray
machines have been the chief mechanical tools for internal observations of the human body since
Wilhelm
Roentgen discovered X–rays in 1901, the development of computers made it possible for better and
more accurate techniques to be applied to scan the human body. These methods employ various
scanners like the CAT, PET, MRI and SPECT.
The CAT is an acronym for Computerized Axial Tomography. This method of scanning generally
involves X–rays and enables scientists to view the inside of the head in a three dimensional format
on a computer screen. PET stands for Positron Emission Tomography and it is much more
complicated than the CAT scan. PET machines bombard the subject with doses of positrons–– the
anti–matter equivalents of the electrons. As the positrons enter the body, they encounter electrons
which are escaping from radioactive elements which have been injected into the bloodstream. When
the positrons and the electrons collide, they give off energy which is recorded by a computer. The
result is a far more detailed 3–D picture of the brain than the one obtained from the CAT machine.
To obtain an even better image, physicians use the MRI, which stands for Magnetic Resonance
Spectroscopy. With these three

questions that a student teacher needs to have answered in order to be able to teach effectively.

The area that controls language (forebrain) shows most development in infancy and early
childhood, when children are starting to gain more and more language (Krause,2010).In my
years of working as a child care worker I have observed that, some children of the same age
seemed to arrive at different developmental stages at different times. For example one child aged
twelve months , could walk and move around obstacles with ease, her language was average for a
child of her age ,yet another child of the same age was only able to sit on her bottom, did not
attempt to walk or even crawl, but her language was outstanding. The brain is such a complex
organ, I have learned the basic structure of the brain, and am able to better understand why some
children in childcare were able to do things, others could not. It seems childhood is a crucial time
for children and brain development, even though genetics play a great part in the way our brain is
structured, a healthy diet, plenty of sleep and a good variety of experiences all play a part in the
way our brain develops from early childhood (Krauss, 2010). There are two main Psychological
theories of learning I would like to discuss, the first being Vygotsky's (social constructivism), the
second Piaget's (personal constructivism) theories .Constructivists learning theories basically centre
on the believe that the student is an active learner and has to build on his/her own learning.

"The Human Brain", by myPerspectives, is an informative article that claims that the brain is a
complex organ that is truly impressive. The brain is a key part of the central nervous system, that
controls the entire body's activities, to simple things such as breathing. These actions are fired
through neurons, that quickly travel through the spinal cord. Surprisingly, the brain transmits these
messages at an unimaginable rate, at 150 miles per hour, through 85 billion cells, called neurons.
These neurons can form up to 10,000 synapses, or connections to each other. By itself, the brain can
create billions of synapses, which change the structure of the brain every time new information is
learned. However, there is still much that scientists

The Structure Of The Brain Essay
Structure of the brain
The brain is made up of 4 main parts and they are:
в—Џthe cerebral cortex,
в—Џlimbic system,
в—Џthe cerebellum
в—Џand the brain stem
The cerebral cortex
The cerebral cortex is split into two cerebral hemispheres (the left and right hemispheres).
Sometimes the right hemisphere is related to creativity and the left hemisphere is related to logic
abilities. It is divided into four sections called lobes, the frontal lobe, parietal lobe, occipital lobe,
and temporal lobe. This is the largest part of the brain. The cerebral cortex is associated with
determining intelligence, influencing your personality, motor function, planning and organization,
processing sensory information and language processing. The cerebral cortex has sensory as well as
motor areas therefore it is responsible for processing sensory information and motor functionality
responses.
The frontal Lobe
The frontal lobe is the biggest lobe. It is involved in motor functions. The frontal lobe helps us to
make decisions as well as assisting to solve problems. It is also connected language and speech
functions. The frontal lobe is located at the front of that brain. It is also the biggest lobe in the brain.
The frontal lobe is the part of the brain that controls important intellectual skills, such as emotional
expression, memory and judgment.
Parietal Lobe
The parietal lobe is behind the frontal lobe and above the temporal lobe. It is responsible for
receiving and processing sensory information and

Essay about the human brain
In this paper one will learn the different parts of the brain and their functions. Although the brain isn't
the largest organ of the human body it is the most complex and controlling organ. It is amazing how
complicated the brain is. The brain controls every action within and out of your body. The brain has
main areas that contain different areas that have specific functions. For instance the basal ganglia
holds the lentiform and the caudate.
The brain isn't just "THE BRAIN" it is actually a group of many parts. They help to inform the brain
on the things going on with the human body. The brain is split in to two main parts, the left and the

The corpus callosum is a bundle of nerves that connects the two hemispheres. The area that passes
and processes information concerning touch, pain, temperature, and pressure on skin is the
thalamus. The limbic system controls your behavior and emotions. It is involved in emotions such
as fear, rage, pleasure, and sorrow. In the prefrontal area of the frontal lobe emotional traits are
controlled. In the temporal lobe expressed behavior is controlled. The parietal lobe discriminates
sensory. The occipital lobe is where visual interpretation takes place. Pons is a crossroad for nerves
going up to the cortex, to the cerebellum and then down the spinal cord. The cortex is the outer gray
area where thinking takes place. The olfactory cortex receives senses from the nose that it then sorts
out. The area that identifies what we see by working out movements, colors, and shapes is the visual
cortex. The area that receives taste senses is called gustatory cortex. The area responsible for
analyzing data, performing memory functions, learning new information, forming thoughts, and
making decisions is the cerebral cortex. The motor cortex is involved in muscle movement. The
cerebellum is vital when carrying out complicated, skilled movements. It is much like a mini brain.
If before you read this paper you thought the brain was a "one man machine" I'm sure your opinion
has changed after reading his paper. It is amazing how god has created the brain to have so many

Essay on Brain Cancer
The brain is made up of millions upon millions of cells. These cells are formed from before birth,
up until about 7 years old. Once these brain cells stop dividing, they are never meant to divide
again. You can see that the division of brain cells is under strict regulation and control. When this
control is lost in a single cell, then it starts dividing in an uncontrolled manner. All of the data
obtained through research on cancer shows that this disease is caused by a rapidly dividing cell,
with no regulators to stop it from dividing. As the cell makes more and more copies of itself, it
grows to form a tumor. This is known as cancer.
When a tumor is developed on the brain, it is called a brain tumor or brain cancer. Brain tumors can

Heredity also plays a role in the development of cancer. If a person's relatives have a history of
cancer, then that person has a higher risk of developing cancer. Genetic variations, particularly those
influencing how the body responds to carcinogens, may create a greater vulnerability to cancer.
Brain cancer is usually accompanied at first by headaches and seizures. Later symptoms could
include nausea, vomiting, fever, change in pulse, and trouble breathing. Other mental changes may
also occur such as difficulty in communication. Symptoms greatly depend on the location of the
tumor. For example, if the tumor were located on the part of the brain controlling vision, then vision
would be affected.
Once a person has been diagnosed with brain cancer, treatment should begin immediately. Treatment
for brain tumors involves any combination of surgery, radiation, and chemotherapy. Some tumors
require several different surgical procedures; some can be treated with radiation alone. Surgery is
the best process to remove a brain tumor. Surgery attempts to remove most, if not all of the tumor.
Once most of the tumor is removed, the rest of the tumor can be removed through a process called
radiotherapy.
Radiotherapy, also called radiation therapy, is the treatment of cancer and other diseases with
radiation. Radiotherapy is used when the entire primary tumor cannot be surgically removed.
Radiotherapy deposits energy

How The Brain Works Essay
Current research shows that mental events cause physical events, and scientists believe examining
single nerves is the key to understanding how the brain works as a complete unit. Understanding the
brain at the nerve cell level will allow scientists to understand how human consciousness works
(Blakeslee, 1992). Furthermore, the brain's thalamus is identified as the possible sensory connector
because it fires 40 impulses per second that sweep through the entire brain (Blakeslee, 1995a). These
findings are a serious implication to Dualism because it states the mind is not physical. If the mind is
not physical, it cannot affect the physical body, so the Dualist theory of two–sided interactions
between the body and mind are false. The...show more content...
Linking the mind to the brain would invalidate Searle's (1980) explanation that artificial intelligence
is impossible because the brain is irrelevant when the mind is concerned. In other words, programs
require machines to run, but the mind is independent of the brain. Recent findings suggest that the
brain is directly linked to the mind, so even creating AI machines will be possible in the future
because the mind is obviously linked to the body through the brain and the nervous system. Although
new theories on human consciousness will obviously assist AI engineers, those theories will
question the reliability of Dualism because they suggest that mind is a material substance that takes
a certain space and creates certain manifestations in the body. In reality, it is possible that the mind
is a material substance. For example, the human eye cannot observe atoms, but they are physical
substances, so there is no reason to define mind as an immaterial substance based on the fact that it
cannot be perceived. Even though the mind is invisible to the human senses, it is possible to
observe the mind. Armstrong's (1980) proposal is that the consciousness is the observer of the
current state of mind. While the human mind is automatically aware of its perceptions in the brain, a
person's consciousness is aware of the mind's awareness of those perceptions (Armstrong, 1980).
However, Armstrong's theory has two implications for Dualism. While Dualism defines mind as a

Left vs. Right Brain
The idea that the left and right sides of the brain can control many different aspects of behavior in
different categories is an interesting one. Four websites which consider this concept are Neuro
Pearls, the American Speech–Language–Hearing Association website, Left vs. Right Brain Modes,
and SPLITTING THE HUMAN BRAIN.
In Left Vs. Right Brain Modes, a direct comparison is presented in several categories. The left
hemisphere is described as verbal, analytical, logical. The right hemisphere is nonverbal (responding
to touch and music), intuitive, and sensory. In some ways the descriptions fit with the "left– handed

The presence of the language function in either hemisphere can be determined using the Wada test,
in which a barbiturate is injected into an internal carotid artery and the effects upon language are
observed.
It is still unknown why handedness and language dominance are related in the brain, or why
language is not bilateral.
The American Speech–Language–Hearing Association (ASHA)s website contains the article
"Language: Left Brain? Right Brain? Both?" which describes the history of discovering the two
hemispheres have different duties to the body, especially in terms of handedness and speech.
Damage to the left side of the brain in most of Dr. Marc Dax's patients caused a loss of speech
(1836). After his death, many more similar reports were recorded.
Much later, the right hemisphere was found to control essential functions as well. Since the effects
of right hemisphere damage are more subtle, as seen in the first website, this conclusion took much
longer to reach. For example, a loss of speech would not be apparent, but instead irrelevant and
rambling speech would be observed.
It is concluded from this site that both hemispheres are needed for a normal use of language, and to
categorize the two hemispheres (as was done in the first website) would be gross oversimplification.

Essay about Addiction and the Brain
Addiction and the Brain
The ponderance that Brain = Behavior and the inherent ramifications of such proves no more
fascinating than when addressed in the context of "Addiction and the Brain". Essential to consider is:
–what exactly is an addictive/abusive substance (drugs of abuse)
–what brain center(s)/chemical(s)are involved
–what does it mean to become physiologically dependent
–how should the concept of addiction be addressed
–how might we use animal models
–and what sort of treatment approaches should be pursued.

All drugs of abuse seem to activate DA release from these two areas although each drug family tends
to work via drastically different psychopharmacological mechanisms.
Besides the obvious appeal of the "high" or elation, which occurs subsequent to drug administration,
a greater influence leading to an increased dosage and necessitated use, would seem the acquisition
of tolerance. There are three subtypes, pharmacokinetic/dispositional tolerance, pharmacodynamic
tolerance, and behavioral tolerance which all prove relevant in the drugs of abuse, with the exception
of the stimulants (cocaine, methylphenidate, etc). Pharmacokinetic tolerance refers to the changes in
substance distribution due to the bodies metabolism of the drug, while pharmacodynamic tolerance
addresses the adaptive changes which have taken place within the system thereby reducing the
efficacy of the drug. The final, behavioral tolerance, seems perhaps at once the most confusing and
most compelling. Behavioral tolerance has to do with the learned tolerance in relation to a specific
situation and it's environmental cues by which the body adapts and prepares itself thus minimizing
the drugs effect ( 6). Thus the physiological dependence, or the need to administer the drug in order
to maintain even a state of normalcy, is a direct result of these developed tolerances. It is the
re–setting of the bodies homeostatic mechanisms in order to adapt for the effect of

1.Biological psychology, of biopsychology, is the application of the principles of biology to the
study of mental processes in terms of bodily mechanisms. The view that psychological processes
have biological (or physiological) correlates, is the basic assumption of the whole field of biological
psychology. Biological psychology is a hopeful domain, one that has much to offer in terms of
improving the quality of life of the healthy as well as those suffering from disorders. It also
contributed important therapeutic data on a variety of conditions, including: Parkinson 's Disease,
Alzheimer 's Disease, Clinical depression, Schizophrenia and a lot others. Humans have very
complex nervous system, they use neurons and neurotransmitters to make the highest active
communication network throughout the body. "most of the body's neurons are found in the central
nervous system(CNS), which consists of the brain and spinal cord" (psychology 5th edition).
"Neuroscience emphasizes that the brain and nervous system are central to understanding behavior,
thought, and emotion. (Van Horn, 2014; Zhao & others, 2014). Therefore, for biological
psychologist all that is psychological is first physiological. All thoughts, feeling & behavior
ultimately have a biological cause." We are benefited from biological approach for diagnosing and
treating human brains Ex. Schizophrenia. Scientists are also able to create medications for different
types of illnesses. Besides having psychologists
