Exploring the Function and Structure of the Cerebrum

1518 Words4 Pages

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 cerebrum has a gyrus structure, which means that that brain tissue is arranged in a convoluted manner. This gyrus structure allows for more brain surface area, which means brain tissue is present to perform …show more content…

Firstly, the cerebrum is capable of neuroplasticity. This is the potential that the brain has to reorganize itself by creating new neural pathways to adapt based on its and the body’s needs. Because of neuroplasticity, the brain is able to recover lost function by activating inherent stem cells that are found around the ventricles to regenerate replacement cells (Drubach, 2000). Secondly, the extensive network of blood vessels in the cerebrum allows nutrients to be delivered efficiently and waste materials to be eliminated efficiently as well. Thirdly, the cerebrum has a high volume (around 75%) of reserve cells, which serve as back up for the restoration of functions after an injury. Lastly, the lobes of the cerebrum each have a distinct function. This allows for highly specialized functioning as well as spares the other functions from getting affected when are area of the brain is damaged (“Cerebrum Anatomy”,

  • Sarah's Life Before And After Accident Analysis

    1618 Words  | 4 Pages

    The main difference between Sarah’s life before and after the accident involved normality; therefore, one of the brain’s main functions may be to ensure that life is as normal as possible. As shown in Sarah’s life before the accident, people usually do not have to think about performing seemingly simple tasks, such as reading the newspaper. In Sarah’s post-accident case, however, she could not recognize the words on a left side of a book that she was reading to her daughter. Due to damage from the injury, a once simple task for Sarah is now a challenge. Another major theme identified in the book related to brain function is that the brain is involved in a variety of tasks, such as motor movements and coordination, sensory information, and learning. This is evident in Sarah’s life before and after her injury. For example, due to Sarah’s left neglect, she could not recognize the position of her left side of her body for walking, and she also could not see the left side of her body. For brain injury, Genova indicated that damage to structures of the brain affects function. Since Sarah’s left side of her body was affected, her right hemisphere was damaged (i.e., the right side of the brain controls the left side of the body and vice-versa). The brain bleed Sarah experienced must have affected certain structures in the right hemisphere, but the brain is capable of healing. Presumably, this is

Dweck also explains that there are different types of mindsets that enable an individual’s development. She claims that there are two types of mindsets that people have. In a growth mindset, people believe that their most basic abilities can be developed through dedication and hard work ( Dweck 1). Furthermore growth mindset individuals love learning and are resilience that is essential for great accomplishment. (Dweck 1). One more theory, Dweck mentioned was fixed mindset. The author states “In a fixed mindset, people believe their basic qualities, like their intelligence

    McNeil (1997), states that an individual with ataxic dysarthria will have “drunken speech” which results from the particular vulnerability of the cerebellum (p. 217). The cerebellum may account for only ten percent of the brain’s volume, but it contains over fifty percent of the total number of neurons in the brain, which means that any damage to it can affect an individual’s motor speech. The cerebellum is responsible for coordination of movement and the process of sensory information. According to Knierim (1997), the cerebellum coordinates the timing and force of muscular contractions so that any skilled or voluntary movements can be appropriate for an intended task. It also processes sensory information from all over the body and assimilates that information into the execution of a movement. Above all, the cerebellum does not initiate any motor commands; it only modifies the movements that are being commanded.

  • Hydrocephalus Essay

    1145 Words  | 3 Pages

    Hydrocephalus is a genetic disorder commonly described as “water on the brain.” In actuality, this is a condition in which there is an excessive accumulation of cerebrospinal fluid (CSF), a clear watery fluid that surrounds the space between the brain and spinal cord, in the brain. Normally, the production together with the absorption process of CSF is specifically balanced to ensure that the brain tissue remains buoyant, that nutrients can be delivered and waste removed, and that there is a compensation for changes in intracranial blood volume. Hydrocephalus blocks this balanced flow as well as absorption, and on account of CSF being produced continuously, 16 oz each day to be exact, the blocking creates a surplus of CSF resulting in the said pressure against the brain tissue. The surplus accretion of CSF additionally motivates ventricular dilation in which the gaps between the brain, known as ventricles, abnormally widen.

    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.

    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).

The mind is the intellect/consciousness that originates in the human brain and manifests itself in emotions, thoughts, perceptions and so forth. This means that the brain is the key interpreter of the mind’s content. Jackson and Nagel seem to resist identifying what we call “mental events” with brain events, for different reasons, while J.J.C. Smart takes the opposing view.
