The Controller of Humans: The Brain Essay

Good Essays
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

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 front part of the left hemisphere. Lies specifically in the third frontal convolution. Broca’s Area contains motor neurons involving the control of speech. (Encyclopedia of Britannica, (n.d.)).
Within the lobes, the parietal lobe lies in that category. This lobes function is to stimuli touch, pressure, temperature, and pain (Lobes of the Brain, (n.d.)). This parietal lobe is divided into two parts, superior parietal and the inferior parietal lobe. Neurons receive sensory information from skin and tongue. This then processes information from the ears and the eyes (Parietal Lobe, (n.d.)).
