Essay on the brain

The brain is made up of many cells, and is the control centre of the body. The brain flashes messages out to all the other parts of the body. The messages travel in very fine threads called nerves. The nerves and the brain make up a system somewhat like telephone poles carrying wires across the city. This is called the nervous system Sep 04,  · The brain is the most complex organ in the human body. It produces our every thought, action, memory, feeling and experience of the world. This jelly-like mass of tissue, weighing in at around The central core of the human brain, often referred to as the “old brain”, is the most primitive part of the brain and can be found in all vertebrates dating back more than million years. The central core is designed to help the human body with basic survival functions such as breathing, heartbeat, movement, balance, and sleep

What is the Nervous System? The nervous system is a network of cells that take messages from the brain and spinal cord to other parts of the body. The nervous system is made up essay on the brain the Central Nervous System and the Peripheral Nervous System. The Central Nervous System has two main parts; the brain and the spinal cord. Essay on the brain the Peripheral Nervous System has the Somatic and the Autonomic Nervous systems included with in it.

While the Peripheral Nervous System has the Somatic and the Autonomic Nervous systems included within it. The Central NS is broken down by two parts the brain and the spinal cord. One part of your forebrain is your cerebrum, or cortex, which is the largest part of the human brain. Cerebrum, or cortex, is broken up into four main parts including the temporal lobe, the frontal lobe, the occipital lobe and lastly the parietal lobe.

First, I will discuss the frontal lobes. According to the America Health Assistance Foundation, the frontal lobe helps control skilled muscle movements, mood, planning for the future, setting goals and judging priorities. It is broken down into three different parts. Neurons and their Electrical Activity The nervous system is composed of millions of nerve cells called neurons. Neurons are the parenchyma of the nervous system which performs every function of the nervous system from simple sensory functions to complex thinking and analysis.

Neurons, essay on the brain, upon receipt of stimuli, transmit responsive signals to other neurons or to effector organs. Clark observes that the anatomy of a neuron is composed of four main parts; the cell body, the dendrites, the axon, and the nerve fibers. Given the importance of each of the neuron components, it is important to discuss how each work separately and in tandem to achieve efficient and appropriate responses in the human body. The human body is compiled with different parts called organs.

It is all controlled and monitor by one main big organ called the brain. The brain is located in the head and weighs about 2. It 's made up of many cells and is basically the control center of the body. There are three types of neurons categorized by their structure and functional differences.

Sensory neurons are groups of nerve cells that receive sensory information from the environment and transmit signals to the central nervous system. Interneurons, the most abundant type of neuron, connect neurons to the brain and convey information between different types of neurons. Lastly, motor neurons transmit signals from the brain or spinal cord to muscle cells or glands throughout the body.

Each of essay on the brain three types of neurons differ in structure in that the cell body somaa key component of every neuron, is located in a different spot along middle of paper nges as a result.

The nervous system carries messages to and from the brain and spinal cord all over the body. It is a complex network of nerves and cells that can be split primarily into 2 sections; the central and peripheral nervous systems.

The Central Nervous System CNS consists of the brain and the spinal chord. It is the control centre of the human body, information from essay on the brain parts of the body is integrated and communicated to the CNS, essay on the brain. The brain is the main controller of most bodily functions, including movement, speech and memory.

To what extent is it true that the brain is a sophisticated information processor? The human brain is the most important part of the nervous system. Many of these functions are localised to a specific area of the cerebrum. The cerebrum is split into four lobes; the frontal, parietal, temporal and occipital lobes, which are specialised to carry out their different roles. The part of the peripheral nervous system known as the somatic nervous system is made of cranial nerves and spinal nerves.

The nerves of the somatic nervous system supply the muscular system and external receptors; this is part of the body control and enables movement Feldman, pg Nervous System The two types of the nervous system are the Central nervous system and the peripheral nervous system.

They are responsible for integrating, processing, and coordinating Sensory data and motor commands the central nervous system, which interprets sensory input and carry information to maintain homeostasis, essay on the brain. The peripheral nervous system consists of the nerves that branch from the brain and spinal cord.

It is a thick bundle of nerve fibers located within the spinal cord. Home Page The Human Brain. The Human Brain Satisfactory Essays. Open Document. Essay Sample Check Writing Quality.

All of the parts are controlled by an organ called the brain, which is located in the head. The brain weighs about 2, essay on the brain. The brain is made up of many cells, and is the control centre of the body.

The brain flashes messages out to all the other parts of the body. Essay on the brain messages travel in very fine threads called nerves. The nerves and the brain make up a system somewhat like telephone poles carrying wires across the city, essay on the brain. This is called the nervous system. The nerves in the body don't just send messages from the brain to the organs, but also send messages from the eyes, earsskin and other organs back to your brain.

Some nerves are linked directly to the brain. Others have to reach the brain through a sort of power line down the back, called the spinal cord. The brain and spinal cord make up the central nervous system. The brain doesn't just control your organs, but also can think and remember.

That part of the brain is called the mind. Eight of essay on the brain bones are interlocking plates, essay on the brain. These plates form the cranium. The cranium provides maximum protection with minimum weight, the ideal combination. The other twenty bones make up the face, jaw and other parts of the skull.

Another way the brain keeps it self safe is by keeping itself in liquid. Nearly one fifth of the blood pumped by the heart is sent to the brain. The brain then sends the blood through an intricate network of blood vessels to where the blood is needed.

Specialized blood vessels called choroid plexuses produce a protective cerebrospinal fluid. This fluid is what the brain literally floats in. A third protective measure taken by the brain is called the blood brain barrier. This barrier consists of a network of unique capillaries. These capillaries are filters for harmful chemicals carried by the blood, but do allow oxygen, water and glucose to enter the brain, essay on the brain. THE DIFFERENT SECTIONS OF THE BRAIN The brain is divided into three essay on the brain sections.

The area at the front of the brain is the largest. Most of it is known as the cerebrum. It controls all of the movements that you have to think about, thought and memory.

Apr 10,  · The brain is the commander of our actions; it tells us what to do, say, act, and react. Music is in our anatomy. It fills our blood stream with the treble of the bass, drop of the beats, and fast tempos. The brain interprets music by releasing certain chemicals, affecting our personality, and improving our motor skills The brain is the control and interpretive mechanism for the senses -- vision, hearing, balance, taste, and smell. The brain also controls other body systems and organs with the release of chemicals allowing a more centralized, and often speedier, coordinated response to environmental stimuli Mar 24,  · Essay On Brain And The Brain as, thinking, emotions, memories and so forth are controlled by the brain.
