Summary of “Brain Basics: Know Your Brain” The brain’s complexity surpasses any other organ in the human body. The brain, weighing three pounds, is protected by a bony shell and fluids. The brain is the hub for intelligence, reaction to senses, cause body movement, and control behavior. The brain is comprised of many cells. However, the most primary cell is the neuron. Sensations, movements, thoughts, emotions, and memories pass through these neurons. Messages are received and carried throughout the body by neurons. This transmitting process occurs during a synapse. During a synapse the neuron is stimulated and releases sacs which release neuro transmitters to cross and attach onto receptors of the receiving cell. The brain is divided into the forebrain, mid brain, and hindbrain. The hindbrain, which includes the brain tem, upper spinal cord, and cerebellum, coordinates vital bodily functions including respiration and heart rate. Next, the midbrain, located at the upper part of the brain stem, controls reflexes, eye movements, and various voluntary movements. The last division of the brain is the forebrain. The forebrain is the largest and most advanced part of the brain. The forebrain’s core is the cerebrum. The cerebrum holds memories, planning strategies, the ability to imagine and think, read and understand, play games, and recognize friends. The cerebrum has two hemispheres that communicate with each other through nerves that lay at the division of the hemispheres. Interestingly, the right hemisphere controls left body movements and the left hemisphere controls the right body movements. The hemispheres are divided into lobes. The two front lobes, behind the forehead, allow for the ability to plan, imagine, and reason. Behind the frontal lobes are the parietal lobes, which provide for the interpretation of taste, aroma, and texture of food. The third
