The Human Brain :: Biology

The human flair enables a person to reason, social occasion intellectually, take up personality and mood, and interact with the environment (Sugerman, 2008, p. 277). Our brain is truly remarkable. Considering how much we politic do non know about the brain just goes to show how complex and amazing the brain is. No other organ is uniform the brain and all other organs would be unable to function without the brain. The three major divisions of the brain are (1) the forebrain, formed by the devil intellectual hemisp heres (2) the midbrain which, includes the corpora quadrigemina and cerebral peduncles and (3) the hindbrain, which includes the cerebellum, pons, and myelin (Sugerman, 2008, p. 277). First off the brain stem is made up of the midbrain, medulla and pons, these connect the hemispheres of the brain, cerebellum, and spinal electric cord (Sugerman, 2008, p. 277). The brain stem is made up of nerve bodies called reticular formation, which is in charge of some of the most vital operations of the body, cardiovascular and airing functions (Sugerman, 2008, p. 277). These two functions are done involuntarily each day. We do not need to think about breathing every few seconds or make our heart beat constantly. This process keeps us awake too. diametric nuclei are responsible for different drive functions accordingly (Sugerman, 2008, p. 278). The cerebellum is composed of remote and white matter, and its cortical surface is convoluted like the surface of the cerebrum. It is also divided by a central fissure into two lobes affiliated by vermis (Sugerman, 2008, 284). The cerebellum has many functions, it is in charge of reflexes, involuntary fine-tuning of motor control and for maintaining balance and posture through extensive neural connections with the medulla (Sugerman, 2008, 284). The little brain or cerebellum, receives discipline from the balance system of the cozy ear, sensory nerves, and the auditory and visual systems. It is involved in the coordination of motor movements as well as basic facets of memory and learning, homeostatic control,.The diencephalon has quadruple major parts epithalamus, thalamus, hypothalamus, and subthalamus. The thalamus is in charge of relaying the cerebral cortex information received from diverse brain regions...Axons from every sensory system (except olfaction) synapse here as the last relay site before the information reaches the cerebral cortex (Sci.uidaho, n.d., para. 2,3). The thalamus surrounds the third ventricle, it allows many sensations to be perceived (Sugerman, 2008, 283).
