The Importance Of The Brain

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.

The frontal lobe is the most anterior section of the brain. The frontal lobe is associated with reasoning, planning, speech, movement, emotions, and problem solving. (2) The frontal lobe is the last to fully mature which is why children and teenagers may have difficult time making correct decisions and thinking about consequences afterwards. Studies using MRI testing have proven that most traumatic brain injuries happen in the frontal region of the brain. (5) The frontal lobe is involved in controlling so many aspects of our life, if the frontal lobe was to be damaged there are many possible outcomes. Patient may lose strength in arms, creating facial expressions becomes more difficult, difficulty in speaking, personality may change, and IQ scores may go down. Scientists have shown IQ tests may decrease because a frontal lobe injury impacts the person’s problem solving abilities. (5)

The parietal lobe is the most superior part of the cerebrum. The parietal lobe receives and analyzes sensory information from touch, temperature, and pain. (1) The primary sensory co...

... brain which consists of the corpus callosum, thalamus, and the hypothalamus. The corpus callosum is the only connection between the left and right hemispheres of the brain. The two hemispheres communicate using neurons across the corpus callosum. (1) This allows humans to do multiple activities at once such as reading and typing at the same time. The thalamus receives sensory information from the spinal cord and cranial nerves and then passes along the message to the midbrain, which will passes along the motor message to the body. An example would be a hand on a hot stove, instantly pain neurons fire in the brain telling the hand to remove from the stove. And lastly the hypothalamus is part of the endocrine and nervous systems. It produces hormones and coordinates with the pons and medulla oblongata to control heart rate, blood pressure, and respiratory rate. (1)
