An Essay On The Brain By Teh Iverson

These psychological disorders originate from different area of the brain. The brain consists of three main parts: the forebrain, midbrain, and hindbrain. The forebrain is made up of the cerebrum, thalamus, and hypothalamus (part of the limbic system). The midbrain comprises the tectum and tegmentum. The hindbrain consists of the cerebellum, pons and medulla. The midbrain, pons, and medulla in conjunction are typically called the brainstem.

. List and briefly describe the 6 primary structures of the brain and their functions:

The part of the brain that I picked is the Cerebellum. The Cerebellum is the part of the brain at the back of the skull in the vertebrates. Its function is to coordinate and regulate muscular activity. The Cerebellum is located behind the top part of the brain stem, it is where the spinal cord meets the brain, the Cerebellum is made of two hemispheres. The Cerebellum receives information from the sensory systems, the spinal cord, and other different parts of the brain, and then it also regulates motor movements. The Cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, and then it results in smooth and balanced muscular activity.

The brain is the center of the nervous system; it receives information, interprets the information and guides the body’s response to the information. Three parts of the brain are the cerebrum, cerebellum, and the diencephalon, along with the brain stem. The cerebrum is the largest part of the brain which handles memory, speech, the senses, emotional responses and much more. Below and behind the cerebrum, attached to the brainstem is the cerebellum. This part of the brain controls our motor functions, ability to balance as well as our ability to interpret information sent to the brain by the eyes, ears and other sensory organs within our body. The brainstem plays as a connector; it connects the brain to the spinal cord which runs down the neck and back. To stay alive your body needs to breathe in air, digest food and circulate blood; the brain stem also acts as a charge to get these functions going. Inside the cerebrum we have the diencephalon, which is also above the brain stem. Sensory function, food intake control and the body’s ability to sleep are the jobs of the diencephalon. A traumatic injury to the brain such as a massive blow or violent shake can cause any of these functions to malfunction which is called a concussion.

The cerebrum makes up three quarters of the brain. In the cerebrum, there is the ability to problem solve, move, think and feel (“Alzheimer’s Disease,”n.d.). The cerebrum can be divided into two halves, the right hemisphere and the left hemisphere. Each hemisphere has four lobes, occipital lobe, parietal lobe, temporal lobe, and frontal lobe. Each lobe has specific tasks. For example, the occipital lobe is responsible for visual images.

There are three parts of the brain: the cerebrum, the brain stem, and the cerebellum. The

The Cerebellum is the second largest part of the brain. The cerebellum occupies the inferior and posterior aspects of the cranial cavity. The Diencephalon extends from the brain stem to the cerebrum. It includes the thalamus, hypothalmas, epithalamus, and subthalmus.

Every single memory, feeling, movement, ability and action has always started and ended in the same place: the brain. Everyday movements like breathing, yawning, or even reading would not be possible without the brain. It holds the everyday life of a human. Even though the brain holds eight major parts, each part contains its own special abilities to contribute to the actions a body is able to do, from the simplest movements to the most complex thoughts.

The human brain is the most important part of the nervous system. The brain along with the spinal cord makes up the central nervous system and together they control all of the body’s important functions, such as motor functions, speech, vision, hearing and also involuntary functions like breathing. 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 cortex is divided into two hemispheres; the left hemisphere is associated with motor control, speech and language functions and logic;

It includes the “hippocampus and amygdala” (Lewis). The hippocampus and the amygdala convert into memory and emotion. The primary functions of the brainstem include “relaying information between the body, perform critical functions in controlling the heart, breathing and consciousness” (Lewis). Between the cerebrum and brainstem lie the thalamus and hypothalamus. “Motor signals to the cortex and is involved in regulating consciousness, sleep and alertness” (Lewis) is the response of the thalamus. Additionally, “the thalamus is the relay station for the information, pain sensation, attention and memory”

Separating the brain into the three main parts gives a much better idea as to how the brain functions. These three parts are the cerebral cortex, the brain stem and the cerebellum. The brain stem is the terminal from the brain to the body. This is where the brain will receive information from the

The brain is responsible for cognitive functions, motor function, along with involuntary functions like breathing. (Boyd, 2008)

The first part of the brain is cerebrum and it consists of four different lobes, it includes frontal lobe, parietal lobe, temporal lobe, and occipital lobe (The Anatomy of The Brain). The function of cerebrum is to operate human’s speech, emotions, learning process, moving control, analyzing touch, and interpreting vision and hearing (The Anatomy of The Brain). The cerebrum is known to be largest part of the brain and it is located in front of the brain (The Anatomy of The Brain). The curled or folded looks is called cortex where it is located on the surface of the cerebrum and consist of around 70% of the 100 billion nerve cells (The Anatomy of The

The cortex consists of four sections, called "lobes". The frontal lobe is connected to reasoning, planning, speech, movement, emotions, and problem solving. The parietal lobe is associated with balance, recognizing, and movement. The occipital lobe is associated with vision. The temporal lobe is connected to hearing, memory, and speech. The cortex is highly wrinkled, making the brain more convenient, as this increases the brain's surface area, giving it more room for neurons. The cerebrum is divided into two hemispheres- the left hemisphere, and the right hemisphere. The right hemisphere is associated with creativity, and the left one is linked with logic. A bundle of nerve fibers, known as the corpus callosum connects these "hemispheres" (Brain Structures and their Functions). The cerebellum, which is also known as the "little brain", is similar to the cerebrum, since it also has two hemispheres and a highly folded surface. This part of the brain is linked with movement and balance. The cerebellum is assumed to be older than the cerebrum "evolutionarily" (Brain Structures and Their Functions). The brain stem controls basic life functions such as blood pressure, breathing, and heartbeat. Scientists say that the brain stem is the simplest part of the brain (Brain Structures and Their Functions).

The brain is an remarkable organ of the human body. Different segments of the brain control different functions and is also known as localization of function. The brain is comprised of the thalamus as well as the cerebellum which is responsible for the controlling and regulating of motor
