The Right Hemisphere Of The Brain - 1436 Words

Memory plays a key role in all living organisms’ lives. The capability to memorize and therefore remember vital functions e.g. location of nutrient/water sources and manoeuvres of defence and or escape when faced with a predator (excluding plants) is the difference between an organisms survival. The human brain is an organ that serves as the centre of the nervous system and is responsible for all human functions (control centre of body) including memory, movement, the five senses, respiratory and circulatory systems and speech. It is located in the head and is therefore close to most primary sensory organs; visual, auditory, haptic, taste and smell, this is essential for quick procession and comprehension of outside stimuli that shape†¦show more content†¦The cortex is divided into four different lobes, the frontal, parietal, temporal, and occipital, which are each responsible for processing different types of sensory information. The frontal lobe, located at the fro nt and upper area of the cortex and carries out mental processes including thinking, planning, speaking fluently (without fault) and is where personalities are formed. The parietal lobe processes sensory information including mainly taste, temperature and touch and is the upper, back part of the cortex. The temporal lobe processes and comprehends auditory sensory information, serves as a storage area, controls memory and is found at the bottom middle area of the cortex, behind the temples. The occipital lobe processes and comprehends all visual sensory information and is located at the bottom, back part of the cortex. The medulla oblongata, responsible for all involuntary functions (without thought), carrying out and regulating life sustaining activities: breathing, swallowing, blood pressure and heart rate, is located along the lower area of the brain stem. The cerebellum is found in the lower area of the brain, below the pons, is subject to voluntary actions (carried out with purpose) and maintains balance and coordination of muscles and the body. The hypothalamus, located above the pituitary gland and below the thalamus, duties include inducing motivational behaviours such as hunger and thirst, helps maintain constant body temperature and
