Five Major Brain Functions

The brain, unlike the heart is the most important part of the body, it weighs up to three pounds and comprises the hefty cerebrum, cerebellum, and the brainstem. The cerebrum which is the largest portion performs all higher cognitive functions. The cerebellum is responsible for motor functions, such as the coordination of movement and balance. The brain stem is dedicated to involuntary functions such as breathing. The brain is comprised of the cerebrum, cerebellum, and brain stem
The largest part of the brain is the cerebrum. it is located on the left side of the brain and is the most sensitive part (Howard, 940). The cerebrum is split into two parts, the left and right, the left controls the right part of the body and the right controls the
There are five different types of lobes, they all control the senses of the body. The lobes of the cerebrum are very curly and sensitive and help send high pitch waves to other parts of the brain (Howard, 941; 964).
It’s the area of the brain that helps you think and understand (Ashwell, 38). It also controls physical growth is the part of the brain closest to the spinal cord and helps the heart know when to beat (Ashwell, 46) The brainstem coordinates motor controls signals sent from the brain to the body, it also controls life supporting autonomic functions of the peripheral nervous system (Baily, www.about education.com). There are motor and sensory neurons which travels through the brainstem allowing for the relay of signals between the brain and the spinal cord (Baily, www.about education.com). There are electrical charges in the brain stem that release neurotransmitters (Ashwell, 39-40). The brainstem is comprised of the medulla oblongata (the part that makes you blush), the pons, and the midbrain which is hidden behind the pons. (Howard, 38). There are cross sections that reveals the three main components of the reticular formation inside the brainstem; the reticular formation is a core of nerve cells forming a network in the midbrain, pons, and medulla oblongata There are three sections in the main component of the reticular formation inside the brainstem the parvocellular, the magnocellular and the raphe nuclei parts (Ashwell, 48). The semiautomatic motor function is breathing, and the motor routines running, walking, and swimming are controlled by the reticular formation.
