The human brain is composed of many important parts of everyday life. The exterior part of the brain has 9 part in which include are divided into different sections, lobes, cortex, and areas. Within the lobes, it includes frontal, parietal, occipital, and temporal lobes. In cortexes, it has the motor cortex, and the sensory cortex. Within the areas section it includes Broca’s Area. The cerebellum is a small version of the brain, and the cerebrum is the like the whole brain. Although the brain is about three pounds blood flows through the brain about 750-1,000 milliliters (mL) per minute, (Disabled World, 2008) (Brain Trivia, (n.d.)).
The brain is quite small but there is still a little brain, the cerebellum. The cerebellum function is to fine movement coordination, muscle tone, and equilibrium. Without the cerebellum, humans would be unable to do many things involving movement. This part is located at the edge of the skull. Within the cerebellum, there are hundreds of millions of neurons in which process data. The little brain is composed of white matter and a thin, outer layer of densely folded gray matter, (Bailey, (n.d.)).
The largest part of the brain is the cerebrum (Cerebrum function, (n.d.)). This part is the largest part of the vertebrate brain. The function of the cerebrum is to process thoughts and actions. The cerebral cortex has hemispheres that have an outer convoluted layer of grey matter. Underneath the cerebral cortex, a layer of white matter exists. In this part of the brain, it is estimated to be 10 billion nerve cells. The hemispheres are two halves of the cerebrum linked by corpus callosum (Dictionary of Biology, 2004).
Frontal lobe is extremely important for humans. The frontal lobe helps humans control decision making, problem solving, and control of purposeful behaviors, consciousness, and emotions (The Brain: (n.d.)). If someone damages the frontal lobe, it could drastically change this person, example Phineas Gage (The brain made simple. (n.d.)). Scientists believe that this lobe may be the best indicator of intelligence (Brainy Facts, (n.d.)). Largest of the lobes, handles brain thinking functions (Frontal Lobe: (n.d.)). This lobe is located in front of the central sulcus (Lobes of the Brain, (n.d.)).
The cortex responsible for coordination of planning, control, and executing voluntary movements is the motor cortex. Motor areas are located in both hemispheres meaning it is located in between. The motor cortex of the left hemisphere control right side of the body. The motor cortexes of the right hemisphere control the left side of the body. Three parts make up the motor cortex. Which are the primary motor cortex, the premotor cortex, and the supplementary motor area (The Motor Cortex. (n.d.)).
Broca’s Area generates speech, writing, language processing and comprehension (Cold Spring Harbor Laboratory, (n.d.)).Named after French scientist Paul Broca. Scientist believe that we speak with the left-brain. Located in the...
