THE BRAIN 2 The Brain The central core and the cerebral cortex of the brain are extremely vital to the function of the human body. Because the central core of the brain regulates involuntary functions such as breathing and blood circulation; without the successful functions of the central core mankind would become extinct. Furthermore, without cerebral cortex functions, the ability to see, smell, touch, taste, move, hear, or think would be gone. The central core is often referred to as the “old brain” because it can be traced back approximately 500 million years to nonhuman species of a primitive type. The central core handles all of the involuntary functions that our body does without conscious thought: such as breathing and blood circulation. The central core has six regions: medulla , cerebellum , pons , reticular formation , thalamus , and hypothalamus . The medulla is part of the hindbrain and controls the unconscious functions, such as breathing, heartbeat, and blood circulation. The cerebellum , also found in the hindbrain , is above the medulla and behind the pons. The section controls the body’s balance. The cerebellum has two halves and constantly monitors the feedback given from muscles in an attempt to coordinate their tension, movement, and placement. If a person consumes an excessive amount of alcohol it will reduce cerebellum

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
