What are the different parts of the brain and what do they do? | Cancer Research UK
Summary
TLDRThe script delves into the brain's anatomy and functions, highlighting the cerebrum, cerebellum, and brainstem. It explains how the cerebrum, divided into left and right hemispheres, controls body parts and processes speech, memory, and sensory information through its four lobes. The cerebellum manages balance and coordination, while the brainstem oversees automatic functions like breathing and heartbeat. The script also mentions the pituitary and pineal glands' hormonal roles and the protective skull and meninges. For more on brain-related health, the script directs viewers to a specified website.

Q & A
What is the primary function of the brain?
-The brain controls everything that we do and how our body functions by sending electrical messages along the spinal cord and nerve fibers to all parts of our body.
How is the cerebrum divided and what does each hemisphere control?
-The cerebrum is divided into two hemispheres, the left and the right. The left hemisphere controls the right parts of our body, and the right hemisphere controls the left parts.
What are the four lobes of the cerebral hemispheres and what do they control?
-Each hemisphere is divided into four lobes: the frontal lobe controls speech, problem-solving, movements, personality, and sensations; the temporal lobe processes sounds and stores memories; the parietal lobe processes touch, temperature, and pain, and recognizes objects; the occipital lobe processes what we see.
What is the role of the cerebellum in the brain?
-The cerebellum, located at the back of the brain, controls our balance, posture, and coordination.
What does the brainstem control and how is it different from other parts of the brain?
-The brainstem controls functions that we don't usually think about, such as breathing, sneezing, coughing, swallowing, and our heartbeat. It is different from other parts as it manages more involuntary and critical functions.
What are the functions of the pituitary gland and pineal gland located in the brain?
-The pituitary gland makes hormones that control various body functions, including growth and the production of sperm and eggs. The pineal gland makes the hormone melatonin, which controls our sleep.
What is the purpose of the skull and meninges around the brain?
-The skull and meninges support and protect the brain. The meninges are membranes that provide additional support and protection.
What is cerebrospinal fluid and what does it do?
-Cerebrospinal fluid (CSF) is a clear fluid that runs between the meninges, the brain, and the spinal cord. It protects them from injuries and provides nutrients.
Where is the cerebrospinal fluid produced and how does it circulate?
-Cerebrospinal fluid is produced by tissues that line the brain ventricles. It circulates in and around the brain and the spinal cord.
What additional information can be found on the website 'see our UK dot org forward slash about - brain - tumors'?
-The website provides more information about the brain, and cancers that affect the brain or spinal cord.
How does the brain receive and process information from the body?
-The brain receives electrical messages from the body through nerve fibers, processes this information, and sends responses back to the body.
Outlines
๐ง Introduction to the Brain's Structure and Functions
The paragraph introduces the brain as the control center for all bodily functions, sending and receiving electrical messages through the spinal cord and nerve fibers. It explains that the brain is divided into different areas, each controlling specific body parts. The cerebrum, the largest part, is divided into two hemispheres, left and right, with each hemisphere controlling the opposite side of the body. The cerebrum is further divided into four lobes: the frontal lobe, which controls speech, problem-solving, movement, personality, and sensations; the temporal lobe, responsible for processing sounds and storing memories; the parietal lobe, which processes touch, temperature, pain, and object recognition; and the occipital lobe, which processes visual information. The cerebellum, located at the back of the brain, controls balance, posture, and coordination. The brainstem, at the lower part of the brain, controls automatic functions like breathing and heartbeat. The pituitary and pineal glands, located in the middle of the brain, produce hormones that regulate various body functions, including growth and sleep. The brain is protected by the skull and meninges, with cerebrospinal fluid providing additional support and protection.

what's the different parts of the brain
and what do they do the brain controls
everything that we do and how our body
functions it sends electrical messages
along the spinal cord and the nerve
fibers to all parts of our body the
nerve fibers also bring electrical
messages back to the brain the different
areas of the brain control the different
parts of our body the largest part of
the brain is called the cerebrum or
forebrain the cerebrum is divided in two
hemispheres the left and the right
hemisphere the left hemisphere controls
the right parts of our body and the
right hemisphere controls the left part
[Music]
each hemisphere is further divided into
four lobes the frontal lobe controls our
speech problem-solving movements
personality and sensations
[Music]
the temporal lobe is where we process
sounds and where our memories are stored
the parietal lobe is were touch
temperature and pain is processed it's
where we recognize objects and process
information when people speak to us the
occipital lobe processes what we see at
the back of the brain is the cerebellum
or hind brain the cerebellum controls
our balanced posture and coordination
the lower part of the brain is called
the brainstem
it controls functions that we don't
usually think about such as breathing
sneezing coughing swallowing on our
heartbeat in the middle of the brain are
the pituitary gland and the pineal gland
the pituitary gland makes hormones that
controlled lots of different body
functions such as our growth on the
production of sperm and eggs the pineal
gland makes the hormone melatonin which
controls our sleep around the brain we
have a collection of bones called the
skull and membranes called meninges the
meninges support and protects the brain
a clear fluid called cerebrospinal fluid
runs between the meninges cerebrospinal

is made by tissues that line the brain
ventricles
the CSF flows in and around the brain
