The Cerebrum
To begin with, the human brain is the most complex part of the human body. It has control to every organ because of a primary functional unit which is the neurons. The exterior part of the brain has specific functions to every organ in the human body. Therefore, the human brain is the most important organ in the human body. A person can be left brained or right brained according to how they act.
The Cerebellum is the trilobed structure of the brain. The cerebellum helps provide smooth coordinated body movement. Examples would balance, posture, coordination, and voluntary movements. It also modifies motor commands to make more movement accurate and adaptive. The cerebellum is located at the back of the brain and contains 50% of total neurons in the brain. (Houghton, M. (2009))
Cerebrum is Latin for brain; the cerebrum is the largest part of the brain as whole. There are fifty hundred to one hundred thousand neurons in the cerebrum .The cerebrum is divided into two hemispheres. The right hemisphere controls imagination and 3d form. The left side controls posture, reasoning, and numbering skills. The two hemispheres have a bridge that is made of bundles of fibers called corpus collusm. (Boeree, C. G. (2003))
Frontal lobe is involved in motor skills including speech and cognitive functions. This is why the writer thinks the brain is the most important organ in the human body. The frontal lobe is located right behind the forehead at the top of a human head. The frontal lobe can also be called the “cerebral cortex”. The cerebral cortex is the seat of emotions and judgment related towards sympathy and empathy. It can understand humor, wordplay, and it recognizes sarcasm and irony. (Hartwig, K. L. (2007, May 27))
Motor Cortex is made up of 3 different areas, the frontal lobe and the central sulcus. The motor cortex is important for coordination and movement. The motor cortex is located in the rear portion of the frontal lobe just before the central sulcus. Pyramidal tract fibers have access directly to structures. Some structures include eye, head, neck trunk, and limb musculature. (Canedo, A. (1997, February 7))
Broca’s area can also be called convolution of Broca. Broca’s are has functions linked to speech production. In other terms it produces language. Broca’s area was discovered in 1861 by Paul Broca. Broca’s area is connected to Wernicke’s area by a neural pathway called accurate fasciculus. (Broca’s Area (n.d.))
Parietal lobe receives all somatosensory input from the body. Wernicke’s area is located in the back of the parietal lobe. Wernicke’s area is important for understanding sensory information for language. Damage to this part of the brain produces sensory aphasia. Patients cannot understand language but can still make sounds. (Amthor, F. (n.d.))
Somatosensory cortex processes input from various systems in the body that are sensitive...
