The nervous system is composed of all nerve tissue in the body. This organ system forms a communication and coordination network between all parts of the body. It plays a major role in everyday activities such as breathing, walking even blinking. It is made up of nerve tissues to receive and transmit stimuli to nervous centers and initiate response. Neurons are nerve cells that transmit signals from one location of the body to another. With damage to the nervous system the body would not be able to function properly. The body has to be well taken care of in order to insure proper regulation. The two anatomical divisions that work hand in hand to help regulate the nervous system are the central and peripheral nervous system. …show more content…
These two hemispheres are connected by the corpus callous. All four lobes and the protectants of the brain are all included in the cerebrum. The cerebrum is the largest part of the brain. It is characterized by learning and senses. The cerebellum is the second largest part of the brain. It is located below the cerebrum at the back of the skull. The main responsibility of the cerebellum is balance and muscle coordination. The brain stem is a vital organ that connects the brain to the spinal cord. Besides connecting the brain and spinal cord the brain stem also keeps people breathing. Sorting the messages that the brain and the rest of the body sends is also a part of its job. The brain is a fragile organ. Although it is protected by the scalp, skull and the three layers of meninges there is still a possibility that it can still be injured. Head injury occurs when an external mechanical force causes brain dysfunction. Penetrating and closed head injuries are the two major types of brain injuries. Penetrating head injuries occur when foreign objects enters the brain and cause damage to specific brain parts. Symptoms vary depending on which part of the brain was damaged. For instance Phineas Gage. A large iron rod was driven through his head, and it destroyed his left frontal lobe. It was said that it changed his personality. After the incident friends did not see him as the “old” Phineas Gage. This case caused neurologist to

Cerebrum: The cerebrum is the main part of the brain, which has two halves, or hemispheres. The right hemisphere controls the left side of the body and deals with things such as creativity, music, and art. While the left hemisphere of the cerebrum controls the right side of the body and is in charge of language, problem solving, and math. The cerebrum’s many tasks are carried out by its outer layer, or its cortex. This has distinct areas that have different roles. Motor areas trigger movement; sensory areas deal with the senses, while association areas clarify information.
The cerebrum is the largest portion of the human brain. It takes up about 4/5 of the weight of the brain and has what is described as a wrinkled cortex. Wrinkled cortex increases the surface area of which increases the number of neurons. This makes human brain to be more efficient than other vertebrates ("Cerebrum vs Cerebellum," n.d.). The cerebrum in divided by the cerebral fissure, which separates it into two hemispheres, the left and right which is being further discussed by a fellow classmate. The two hemispheres are connected by the corpus callosum. Both hemispheres can also be divided into four lobes which we know as the frontal, parietal, temporal, and occiptal lobes. The frontal lobe helps aids us with reasoning, speech, movement,
The nervous system consists of the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let 's take a look at the central nervous system.
The brain is a crucial part of the human body. Our abilities to learn, remember things, and feel emotions are controlled by this very vital organ. Also, the spinal cord is a crucial part of the central nervous system. The nerves that send messages to the body are located all throughout the spinal cord. Additionally, within the brain there are three major regions. They are called the central core, the limbic system, and the cerebral cortex, which has four hemispheres. The four hemispheres are the occipital lobe, the temporal lobe, the parietal lobe, and the frontal lobe.
In my personal opinion, I think the cerebellum is the main part of the human brain, in fact I think is the brain part that make us uniquely human. The cerebellum receives information from sensory systems, the spinal cord, and other parts of the brain and then regulates motor movement. It coordinates voluntary movements such as posture, balance, coordination and speech resulting in smooth and balanced muscular activity. The cerebellum looks like a small brain, I read in the textbook, (page 87) that Cerebellum means Little brain and I found that very amusing to read about. It is amazing how the cerebellum has such importance in our body,in page 87 we can see a clear of example how people can sit upright because the cerebellum controls all the
The cerebellum is a larger portion of the brain which are all vertebrates. It is ten percent of the brain. The cerebellum can be separated in three parts, the midline vermis, and two lateral hemispheres. The hemispheres are large compared to other organisms and are used for motor control. The vermis is used for controlling muscle tone and level of force. Over all the cerebellum main functions are to control the cognitive
There are two main divisions that comprise the nervous system: the central nervous system consisting of the brain and the spinal cord and the peripheral nervous system consisting of somatic and autonomic nervous systems (Kalat, 2013). The brain and the spinal cord make up the central nervous system and is responsible for the transmission of nervous impulses as well as receiving sensory information (Siegal, 1999). The peripheral nervous system, consisting of cranial nerves, spinal nerves, and peripheral ganglia, is responsible for transmitting information to the central nervous system as well as the rest of the body (Hubbard, 2013).
As humans, we all utilize the organ known as the brain to keep ourselves alive. The brain must be working in optimal condition to ensure our survival and the continuation of our species. Not only is this vital organ necessary to sustain life, it also is used to perform common everyday tasks as well as more complex ones. Similar to all organs, the brain is made up of many different components. The three main sections are the cerebrum, the brain stem, and the cerebellum (New Book of Knowledge, 364). These three divisions interact “to coordinate how we perceive, move, think, and feel” (New Book of Knowledge, 364). The cerebrum is especially important because most functions take place there. Even the cerebrum itself is composed of various portions. There is much to know about the cerebrum, including its functions, composition, and development.
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.
The cerebrum, which controls thought and action, is the biggest part of the human brain. It is also very wrinkled and this feature is noted for the potential increased size of the brain and the number of neurons that help bring the brain’s commands back and forth to the body. It is divided into two halves: the left and right hemispheres. Often, the left hemisphere is associated with logic functions and the right hemisphere is associated with creative abilities. It is then divided further into four parts: the frontal, parietal, occipital, and temporal lobes.
Cerebrum – what is it? Largest part of the brain. It contains a left and right hemisphere – the left hemisphere controls logic, sequences, and math whereas the right side is more intuitive, artistic and creative. The right hemisphere controls the left half of the body and the left hemisphere controls the right half of the body. These hemispheres are separated by the corpus callosum
Neurons are the basic data processing units for the human brain. Every neuron can receive 1000 electrical impulses from other neurons. Impulses that all come at the same time are added together and, if they are strong enough, they can generate electrical discharge, which is known as action potential or a nerve impulse. Neurons have a cell body or soma. Additionally, they have myelin. Myelin allows nerve impulses to move quickly from one neuron to another, which makes rapid signal transmission possible. It is a critical part of the nervous system and if it is not in a body it can be devastating, which can be exhibited through multiple sclerosis. The nervous system plays an important role in the body 's ability to feel sensations and is made up of neurons, cells, and are necessary to perform even the simplest tasks. Your body has billions of tree-like processes that are involved in sensing this information from the environment, relaying the information to your brain, and sending information to carry out the act of answering your cell phone as a response to the initial sensory input.
