“The human brain enables a person to reason, function intellectually, express personality and mood, and interact with the environment” (Sugerman, 2008, p. 277). Our brain is truly remarkable. Considering how much we still do not know about the brain just goes to show how complex and amazing the brain is. No other organ is like the brain and all other organs would be unable to function without the brain. “The three major divisions of the brain are (1) the forebrain, formed by the two cerebral hemispheres; (2) the midbrain which, includes the corpora quadrigemina and cerebral peduncles; and (3) the hindbrain, which includes the cerebellum, pons, and medulla” (Sugerman, 2008, p. 277). First off the brain stem is made up of the midbrain, medulla and pons, these connect the hemispheres of the brain, cerebellum, and spinal cord (Sugerman, 2008, p. 277). The brain stem is made up of nerve bodies called reticular formation, which is in charge of some of the most vital operations of the body, cardiovascular and respiration functions (Sugerman, 2008, p. 277). These two functions are done involuntarily each day. We do not need to think about breathing every few seconds or make our heart beat constantly. This process keeps us awake also. Different nuclei are responsible for different motor functions accordingly (Sugerman, 2008, p. 278).
“The cerebellum is composed of gray and white matter, and its cortical surface is convoluted like the surface of the cerebrum. It is also divided by a central fissure into two lobes connected by vermis” (Sugerman, 2008, 284). The cerebellum has many functions, it is in charge of reflexes, involuntary fine-tuning of motor control and for maintaining balance and posture through extensive neural connections with the medulla (Sugerman, 2008, 284). The little brain or cerebellum, “receives information from the balance system of the inner ear, sensory nerves, and the auditory and visual systems. It is involved in the coordination of motor movements as well as basic facets of memory and learning, homeostatic control,”.
The diencephalon has four major parts: epithalamus, thalamus, hypothalamus, and subthalamus. The thalamus is in charge of “relaying the cerebral cortex information received from diverse brain regions...Axons from every sensory system (except olfaction) synapse here as the last relay site before the information reaches the cerebral cortex” (Sci.uidaho, n.d., para. 2,3). The thalamus surrounds the third ventricle, it allows many sensations to be perceived (Sugerman, 2008, 283).
Although the brain only weighs about three pounds, it is a very powerful and essential organ in the body (Brain Structures and Their Functions). The cerebrum, cerebellum, and the brain stem are the three main parts of the brain. The cerebrum fills up most of the skull, its main functions are for remembering, problem solving, thinking, and feeling (Bellamy 23). It also controls movement throughout the body. The cerebellum is located towards the back of the head. It controls mostly just coordination and balance (Brain Structures and Their Functions). The brain stem is underneath the cerebrum and in front of your cerebellum. It attaches the brain to the spinal cord and controls functions like breathing, digestion, heart rate and blood pressure (Carter 12). The brain is also divided into halves. The left side of the brain controls the right side of the body, while the right side of the brain, controls the left side of the body (Bellamy 17).
When examining the development of the human brain, it is known the first portion to develop is the cerebellum. The cerebellum is the seat of human life support systems and our natural instincts. Sharing the fight or flight responses, the experience of apprehension towards looming animals or objects, and a need to live and reproduce are innate. These all may be experienced to differen...
The cerebrum is located at the anterior-most part of the brain and is responsible for the combination of complex sensory and neural functions, as well as the initiation and coordination of voluntary activity in the body. It is the largest brain structure in humans and makes up two-thirds of the total mass of the brain (“Cerebrum Anatomy”, 2015). Its surface, a covering made up of grey matter usually 2-4mm thick, is called the cerebral cortex and is mainly made up of the cell bodies of neurons. The cerebral cortex is responsible for integrating sensory impulses, directing motor activity, and controlling higher intellectual functions. It is also responsible for the state of consciousness, which still remains a mystery to neurologists and the rest of the science community (Swenson, 2007).
The primary motor area is controls individual muscles. Most of the neurons in this primary motor area control body areas having the finest motor control including the hands. The cerebellum at the back of the neck coordinates muscle motion, in this case- hand- eye coordination. The cerebellum provides the precise timing for skeletal muscle activity and controls our balance and equilibrium. The cerebellum can be compared to an automatic pilot continuously comparing the brains intentions while actual body performance by monitoring body position and amount of tension in various body parts. In this lab, the most important factor we use is the sense of sight, which the occipital lobe is responsible for. The occipital lobe is in charge of your vision and object recognition.
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 body and then send out signals back to the body to tell it the correct response. When it comes to everyday reaction and natural bodily functions, the cerebral cortex will kick in, made up of pretty much all “grey matter.” The cerebral cortex is the hub for most of your reactions and memories. The cerebellum is mainly responsible for regulating the levels in the body, organizing the information and memories the brain receives and it also controls with the “thought process.”(brains and interactions, NP BBCsci.)
The brain has many different parts to it which help one function through daily life; parts such as the cerebrum which controls voluntary movement and regulates functions such as thinking, speaking and the ability to recall information. The cerebellum controls the balance and coordination and finally the brain stem, which consists of the medulla oblongata and the spinal cord which controls all involuntary functions such as breathing, heart rate and blood pressure. The brain stem is also able to carry out these actions even when someone is asleep. To fully understand how crucial the brain is to survival one must understand the functions of the brain stem.
The brain is an amazing thing, but it’s also such a weird thing. We just have this 3 pound ball of nervous tissue inside of our skull that helps us walk, talk, move, solve problems, write, read, imagine impossible situations that will stress you out at 4 AM , feel emotions, stores memories, and so many other incredible things.
The brain is one of the most interesting yet the most complex part of the body. Since no one can really see what’s inside, it’s a big question for most people on how it works. The brain is made up of more than 100 billion neurons that communicate through the synapse. It controls all the function of the body, receive and interprets information and process thoughts and emotions (Hines, 2016). It is one of the most important part of the body. How we remember, how we think, do and etc. is made possible because of the brain. The brain is divided into three main parts: cerebellum, cerebrum and brainstem. Each part has its own specialised area on the body in order to function well (Hines, 2016).
...ke structure that connects the cerebrum with the spinal cord. The brain stem controls the reflexes and automatic functions, such as heart rate, blood pressure, limbs movement and visceral functions like digestion and urination (Striedter 529). Well these three divisions are very important to the human brain and body, these are the divisions that allow us to be able to move, speak, and about any other action you could think of.
The brain is an incredible part of our body and it controls everything from body coordination, thinking processes, and regulating body functions. The brain has enough energy to power a 25watt bulb. Now that’s power! The brain is composed of the cerebrum (and its lobes), the thalamus, hypothalamus, brainstem and cerebellum. The cerebrum consists of the; frontal lobe, parietal lobe, temporal lobe, and the occipital lobe. It’s the largest part of the brain and accumulates 85 percent of the weight. (1) Each part of the brain has its own specific and unique functions. Scientists have and still are studying to unlock the mysteries and full potentially of the human brain.
In many opinions it is thought that the brain and the neurons have less than importance than the heart. However, there is large quantities that people disagree that the brain and neurons are an important factor in our body. One study showed, the brain is the one that control every part of the body. Awhile the neurons travels across a synapse se...
Firstly, there is various of sensing activities as in seeing and hearing as in a sense of understanding of what is seen and heard. Secondly the sense of feeling in numerous parts of the body from the head to the toes. The ability to recall past events, the sophisticated emotions and the thinking process. The cerebellum acts as a physiological microcomputer which intercepts various sensory and motor nerves to smooth out what would otherwise be jerky muscle motions. The medulla controls the elementary functions responsible for life, such as breathing, cardiac rate and kidney functions. The medulla contains numerous of timing mechanisms as well as other interconnections that control swallowing and salivations.

Since the brain and the nervous systems are in need of each other to perform their functions it is important to look at the brain and all of it 's features. The brain is the control center that process the majority of all the bodies functions. The spinal cord is responsible for certain simple muscle reflexes but the brain process both conscious and unconscious.
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.
