Introduction The brain is an extremely fundamental organ in all vertebrates and most invertebrates. It is considered to be the most complex organ of the human body. The brain is responsible for coordination of the qualities that define humanity. It for example deals with matters of intelligence, interpretation of the senses, facilitation of body movement as well as controlling human behavior. The brain plays a great role in giving meaning to things that happen around us through its various fundamental functions. Through the five senses (smell, touch, sight, taste and hearing), the brain receives messages that direct our behavior and actions. The messages could also be stored in the memory for use in future (Bell 12). As an organized structure, the brain is divided into different parts each serving significant function(s). This piece of work gives a critical analysis of the anatomy of the brain. The Brain Anatomy The anatomy of the brain is a complex concept that is difficult to understand. This is more so due to its complicated structure and function. It acts as a center in which controlled activities are carried out. This is mainly achieved through the processes of receiving, interpretation, and directing of sensory information in the whole body. The brain is divided into diverse parts that are charged with different significant functions. The individual functions are combined in a systematic manner to bring about an absolute success in the functioning of the brain as a whole. Some of the basic parts of the brain include the cerebral cortex lobes namely; the temporal lobes, the frontal lobes, the occipital lobes, the parietal lobes, the prefrontal cortex, and the limbic system. The brain could also be divided into three major parts namely; the forebrain, the midbrain, and the hindbrain. The Frontal Lobes The frontal lobes are responsible for body processes such as planning, movement, problem solving, and decision making among others. The frontal lobes are divided into three main parts include, the premotor area, the motor area, and the prefrontal cortex. The general functions of the frontal lobes include; reasoning, memory, motor functioning, planning, and judgment as well as impulse control (Mercier, Kitasako and Hatton 170). The Prefrontal Cortex System This is considered to be the most evolved brain system. It is the core part of the frontal lobes of the brain. It plans intricate cognitive behaviors, decision making, personality expression as well as shaping social behavior. Other functions involve impulse control, judgment, critical and forward thinking, allowing one to learn from experience and mistakes, perseverance, and problem solving among others. It works interdependently with the other parts of the brain. Some of the problems associated with the prefrontal cortex include short attention span, impulse control problems, misperceptions, social and test anxiety, inability to persevere, procrastination, poor judgment, short term memory problems, hyperactivity, difficulty in learning from experience, and chronic lateness among others. The premotor and motor areas on the other hand play a great role in the control of execution of voluntary and involuntary muscle movement. This is made possible due to the presence of nerves. While the motor is in cha
