The Human Brain : The Nervous System Of The Human Body

The nervous system in general is quite a complex and sophisticated system which is responsible for regulating and coordinating the body’s activities. The central nervous system consists of the brain and spinal cord, mainly responsible for gathering information and responds to any changes within environment.

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 can be considered the most complex organ in the body and the centrepiece of the nervous system. Although the brain works as a unified whole, neuroscientists have identified areas within it that perform specific functions. This makes the brain interconnected by three different layers: the central core, the limbic system, and the cerebral cortex. All of which contain structures that regulate everyday life and psychological function.

The brain is the most important organ for regulating human behavior and thought. The brain is very complex and has taken centuries to discover how it functions. The brain is separated into four distinct regions or lobes. These regions are called the frontal lobe, the occipital lobe, the temporal lobe, and the parietal lobe. The frontal lobe is located directly behind the forehead and is the brain region that controls higher level thinking such as memory, planning, and judgment. The frontal lobe also contains motor cortex which allows voluntary movements. Another vital brain region is the occipital lobe. The occipital lobe can be found in the back of the brain. Its job is to process and store visual information. The occipital lobe

Nervous System: The human nervous system is a communication that controls all parts of your body (communication within environment) — whether it is voluntary or involuntary.

The human body consists of many important systems. The nervous system is one of these that ensure survival of a person. The nervous system is split into two main parts. The spinal cord and the brain make up the Central

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 brain resides in the cranium, and is a perplex organ of several tissue layers and neural networks (Tang-Schomer, et al., 2014). Some parts of the brain include the cerebral cortex and thalamus, which support cognition and relay signals, respectively. Furthermore, the brain is responsible for both autonomic and somatic bodily mechanisms (OpenStax College, 2013). Considering the diversity of structural functions within the brain, the brain’s overall function is an executive one that controls the nervous system by means of perceiving and communicating electrical signals.

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

It made up of more than 100 billion nerves that communicate in trillions of connections called synapses. There are specialized areas that work together to make up the brain. The outermost layer of brain cells called the cortex is where thinking and voluntary movements begin. The brain stem is between the spinal cord and the rest of the brain and controls basic functions like breathing and sleep. The part that is responsible for balance is known as the cerebellum. Additionally, the brain is divided into five lobes: the frontal lobe, parietal lobe, temporal lobe, occipital lobe, and insula. The frontal lobe is responsible for problem solving, planning, speech, movement, judgment and motor function. The parietal lobe manages sensation, temperature, touch, body position, and handwriting. The temporal lobe is involved with memory and hearing. The occipital lobe contains the brain’s visual processing system. The insula is responsible for memory, taste, and integration of information from the other four lobes. There a layer of tissue called the meninges which surrounds the brain and the skull (cranium) to protect the brain from

The cerebrum is the largest part of the brain and is involved in mental activities, such as thinking, learning and memory, as well as the perception of senses and the initiation and control of voluntary muscle contraction. It has 3 basic functional areas:

The brain has the capacity to observe, feel, understand, and remember information. The brain develops from the neural tube and has three main components: cerebellum, cerebrum, and the brain stem. Each components is composed of the frontal, temporal, parietal, and occipital lobes. Inside of each one is a cortex, white matter, and basal nuclei. Cerebral cortex is called a gray matter which is outside of the cerebrum. Cerebellum is near the base of the head. Brain stem connects to the spinal cord the mesencephalon which is the medulla-oblongata that contains midbrain, pons, and cerebellum.

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”

The nervous system consists of the brain, spinal cord and peripheral nerves. The brain and spinal cord form the central nervous system and nerves form the peripheral nervous system. The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes from both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.

The brain is one of the most complex organs in the human body. Nerves in the brain control specific parts of the body. Some nerves directly control parts of the head such as, the eyes, ears, and mouth. Other nerves connect with the spinal cord parts of the body to control senses and other functions the body performs such as walking. (Johns Hopkins Medicine, 2017) The brain is separated into three main parts. These are the cerebrum, the cerebellum, and the brain stem. The different parts are responsible for completing different actions and controlling different parts of the body.
