The Brain And Spinal Cord
The brain and spinal cord make up the central nervous system . The CNS is made of different types of tissues and cells which can develop into different types of tumours.
To understand tumours of the CNS it helps to know about the:
- parts of the brain and spinal cord
- types of cells and tissues
What are the different parts of the brain and what do they do?
The brain controls everything we do and how our body functions.
It sends electrical messages along the spinal cord and the nerve fibres to all the parts of our body. The nerve fibres 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 into hemispheres: the left and the right hemisphere. The left hemisphere controls the right part of our body. And the right hemisphere controls the left part. Each hemisphere is further divided into 4 lobes.
The frontal lobe controls our speech, problem solving, movement, personality and sensations. The temporal lobe is where we process sounds and where our memories are stored. The parietal lobe is where touch, temperature and pain is processed. It is where we recognise objects and process information when people speak to us. The occipital lobe processes what we see.

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

How Does The Nervous System Work
The basic workings of the nervous system depend a lot on tiny cells called neurons. The brain has billions of them, and they have many specialized jobs. For example, sensory neurons send information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain to the rest of the body.
All neurons, however, relay information to each other through a complex electrochemical process, making connections that affect the way we think, learn, move, and behave.
Intelligence, learning, and memory. As we grow and learn, messages travel from one neuron to another over and over, creating connections, or pathways, in the brain. It’s why driving takes so much concentration when someone first learns it, but later is second nature: The pathway became established.
In young children, the brain is highly adaptable. In fact, when one part of a young child’s brain is injured, another part often can learn to take over some of the lost function. But as we age, the brain has to work harder to make new neural pathways, making it harder to master new tasks or change set behavior patterns. That’s why many scientists believe it’s important to keep challenging the brain to learn new things and make new connections it helps keeps the brain active over the course of a lifetime.
Smell. Olfactory cells in the mucous membranes lining each nostril react to chemicals we breathe in and send messages along specific nerves to the brain.
Functions Of The Cerebral Cortex
The cerebrum is the seat of many of the higher mental functions, such as memory and learning, language, and conscious perception, which are the subjects of subtests of the mental status exam. The cerebral cortex is the thin layer of gray matter on the outside of the cerebrum. It is approximately a millimeter thick in most regions and highly folded to fit within the limited space of the cranial vault. These higher functions are distributed across various regions of the cortex, and specific locations can be said to be responsible for particular functions. There is a limited set of regions, for example, that are involved in language function, and they can be subdivided on the basis of the particular part of language function that each governs.

Cerebrum And Cerebral Cortex
The cerebrum makes up most of the brain. It is found in the cranial vault. The cerebrum consists of two cerebral hemispheres and five lobes. All lobes are named according to the cranial bones on which they lean: frontal, parietal, temporal, occipital and insular lobes. The insular lobe is hidden just beneath the frontal, temporal, and parietal lobes. Insula means island, which the insular lobe is indeedan isle of gray matter hidden under the surface of the cerebrum.
Youll probably encounter the termlimbic lobe as well, but this is not an actual lobe. Rather its a functional group of interconnected regions of the brain which together control emotions, memory and spatial perception. The cerebrum together with the hippocampus, amygdala, olfactory bulb, and basal ganglia comprise the telencephalon.
The most superficial layer of the cerebrum is the cerebral cortex. It is a layer of grey matter which displays numerous folds , can be categorization structurally or functionally , and is home to areas such as the primary motor cortex and the primary somatosensory cortex, both of which house a homunculus.
White matter connections extend between the cerebral cortex grey matter to other parts of the same cerebral hemisphere to the opposite hemisphere and to structures outside the cortex . Learn more about cerebral cortex and its structure with our study units:
The Hypothalamus Manages Sensory Impulses Controls Emotions And Regulates Internal Functions
The hypothalamus is part of the diencephalon, a region of the forebrain that connects to the midbrain and the cerebrum. The hypothalamus helps to process sensory impulses of smell, taste, and vision. It manages emotions such as pain and pleasure, aggression and amusement. The hypothalamus is also our visceral control center, regulating the endocrine system and internal functions that sustain the body day to day. It translates nervous system signals into activating or inhibiting hormones that it sends to the pituitary gland. These hormones can activate or inhibit the release of pituitary hormones that target specific glands and tissues in the body. Meanwhile, the hypothalamus manages the autonomic nervous system, devoted to involuntary internal functions. It signals sleep cycles and other circadian rhythms, regulates food consumption, and monitors and adjusts body chemistry and temperature.

S Of The Brain: Structures Anatomy And Functions
The human brain is one of the largest and most complex organs in the body. It controls your emotions, thoughts, speech, memory, creativity, breathes, movement, and stores information from the outside world. This article discusses the different parts of the brain and the function of each structure.
The brain is a 3-pound organ that contains more than 100 billion neurons and many specialized areas. There are 3 main parts of the brain include the cerebrum, cerebellum, and brain stem. The Cerebrum can also be divided into 4 lobes: frontal lobes, parietal lobes, temporal lobes, and occipital lobes. The brain stem consists of three major parts: Midbrain, Pons, and Medulla oblongata. Although each structure has a distinct function, they work together to control all functions of the body.
What Is The Brainstem And What Does It Do
In addition to connecting the brain to the rest of the nervous system, the brainstem has a number of essential functions. To simplify things, I’ll discuss some of the functions associated with each of the three major regions of the brainstem. It should be noted, however, that the organization of the brainstem is very complex and this is just an overview.

What Connects The Brain To The Spinal Cord
- May 15, 2019
- /By ithelpdesk
The spinal cord is perhaps one of the most impressive and important structures in the body. It transmits signals from touch receptors to the brain as well as signals from the brain to other parts of the body to allow movements to be made.
Signals from the brain that are responsible for things such as heart rate, breathing and blood pressure are also transmitted through the spinal cord. The spinal cord also acts as support frame that helps us remain upright.
In laymans terms, explaining the brain in relation to the spinal cord can be achieved with this effective analogy:
Think of the brain as a postal office, sending and receiving mail from places around the world. On the other hand, the spinal cord is like the mail trucks, which are responsible for carrying the mail to and from the postal office.
The brain is connected to the spinal cord by the brain stem, which consists of three distinct parts: the midbrain, the medulla oblongata, and the pons.
What Does The Brain Do
The brain controls what we think and feel, how we learn and remember, and the way we move and talk. But it also controls things we’re less aware of like the beating of our hearts and the digestion of our food.
Think of the brain as a central computer that controls all the body’s functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part.
When a message comes into the brain from anywhere in the body, the brain tells the body how to react. For example, if you touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away. Luckily, this neurological relay race happens in an instant.

Central Nervous System: Brain And Spinal Cord
Our bodies couldnt operate without the nervous system – the complex network that coordinates our actions, reflexes, and sensations. Broadly speaking, the nervous system is organised into two main parts, the central nervous system and the peripheral nervous system .
The CNS is the processing centre of the body and consists of the brain and the spinal cord. Both of these are protected by three layers of membranes known as meninges. For further protection, the brain is encased within the hard bones of the skull, while the spinal cord is protected with the bony vertebrae of our backbones. A third form of protection is cerebrospinal fluid, which provides a buffer that limits impact between the brain and skull or between spinal cord and vertebrae.
How The Spinal Cord And Muscles Work Together
The spinal cord is divided into five sections: the cervical, thoracic, lumbar, sacral, and coccygeal regions. The level of injury determines the extent of paralysis and/or loss of sensation. No two injuries are alike.
This diagram illustrates the connections between the major skeletal muscle groups and each level of the spinal cord. A similar organization exists for the spinal control of the internal organs.

Why Cant The Central Nervous System Repair Itself After Injury
Many organs and tissues in the body can recover after injury without intervention. Unfortunately, some cells of the central nervous system are so specialized that they cannot divide and create new cells. As a result, recovery from a brain or spinal cord injury is much more difficult.
The complexity of the central nervous system makes the formation of the right connections between brain and spinal cord cells very difficult. It is a huge challenge for scientists to recreate the central nervous system that existed before the injury.
What Is The Spinal Cord
Your spinal cord is a cylindrical structure that runs through the center of your spine, from your brainstem to your low back. It’s a delicate structure that contains nerve bundles and cells that carry messages from your brain to the rest of your body. Your spinal cord is one of the main parts of your nervous system.

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.
Structure And Function Of The Spine
The spine is made up of 26 bones divided into 5 sections. These bones surround and protect the spinal cord. This includes 24 vertebrae , the sacrum and the coccyx.
Cervical region These are 7 vertebrae at the top of the spine that run from the base of the skull to the lowest part of the neck.
Thoracic region These are 12 vertebrae that run from the shoulders to the middle of the back.
Lumbar region These are 5 vertebrae that run from the middle of the back to the hips.
Sacrum This is a large section of fused vertebrae at the base of the spine.
Coccyx This is a small, thin section of fused vertebrae at the end of the spine.
Between the vertebrae are the discs .
Disc A layer of cartilage found between the vertebrae. Discs cushion and protect the vertebrae and spinal cord.

Introducing The Notion Of A Complex Biological Neural Code As A Way Of Neuromodulation
An artificial spinal cord stimulation to treat chronic pain can be considered a simple stimulation paradigm. However, the neural code caused by seizures induced by PTZ coming from a sender rat can be regarded as a complex biological stimulation paradigm due to its nature and also due to a much bigger number of variables. Hence, further research can be done to study the effects of complex biological stimulation paradigms as possible new ways of neuromodulation.
How Does The Central Nervous System Protect Itself From Injury
The central nervous system is better protected than any other system or organ in the body. Its main line of defense is the bones of the skull and spinal column, which create a hard physical barrier to injury. A fluid-filled space below the bones, called the syrnix, provides shock absorbance.
Unfortunately, this protection can be a double-edged sword. When an injury to the central nervous system occurs, the soft tissue of the brain and spinal cord swells, causing pressure because of the confined space. The swelling makes the injury worse unless it is rapidly relieved. Fractured bones can lead to further damage and the possibility of infection.

About The Brain And Spinal Cord
Together, the brain and spinal cord form the central nervous system. This complex system is part of everything we do. It controls the things we choose to dolike walk and talkand the things our body does automaticallylike breathe and digest food. The central nervous system is also involved with our sensesseeing, hearing, touching, tasting, and smelling as well as our emotions, thoughts, and memory.
The brain is a soft, spongy mass of nerve cells and supportive tissue. It has three major parts: the cerebrum, the cerebellum, and the brain stem. The parts work together, but each has special functions.
The cerebrum, the largest part of the brain, fills most of the upper skull. It has two halves called the left and right cerebral hemispheres. The cerebrum uses information from our senses to tell us what’s going on around us and tells our body how to respond. The right hemisphere controls the muscles on the left side of the body, and the left hemisphere controls the muscles on the right side of the body. This part of the brain also controls speech and emotions as well as reading, thinking, and learning.
The cerebellum, under the cerebrum at the back of the brain, controls balance and complex actions like walking and talking.
The brain stem connects the brain with the spinal cord. It controls hunger and thirst and some of the most basic body functions, such as body temperature, blood pressure, and breathing.
Spinal Cord Topography And Roots
Cross-Section of Spinal Cord, Mid-Thoracic Level: Note the commissure, rendered in grey.
The spinal cord is compressed dorsoventrally, giving it an elliptical shape. The cord has grooves in the dorsal and ventral sides. The posterior median sulcus is the groove in the dorsal side, and the anterior median fissure is the groove in the ventral side.
Each segment of the spinal cord is associated with a pair of ganglia called dorsal root ganglia, situated just outside of the spinal cord. These ganglia contain cell bodies of sensory neurons. Axons of these sensory neurons travel into the spinal cord via the dorsal roots.
The grey matter, in the center of the cord, is shaped like a butterfly and consists of cell bodies of interneurons and motor neurons, as well as neuroglia cells and unmyelinated axons. Projections of the grey matter are called horns. Together, the grey horns and the grey commissure form the H-shaped grey matter.
