The Human Brain :: Biology

The human brain enables a person to reason, hold out intellectually, express personality and mood, and interact with the environment (Sugerman, 2008, p. 277). Our brain is truly remarkable. Considering how often we still do not know about the brain ripe goes to show how complex and amazing the brain is. No other organ is like the brain and all other organs would be futile to function without the brain. The three major divisions of the brain are (1) the forebrain, formed by the two cerebral hemispheres (2) the midbrain which, includes the corpora quadrigemina and cerebral peduncles and (3) the hindbrain, which includes the cerebellum, pons, and medulla (Sugerman, 2008, p. 277). First clear up the brain stem is made up of the midbrain, medulla and pons, these connect the hemispheres of the brain, cerebellum, and spinal anesthesia cord (Sugerman, 2008, p. 277). The brain stem is made up of nerve bodies called networklike formation, which is in charge of some of the most vital operations of the body, cardiovascular and respiration functions (Sugerman, 2008, p. 277). These two functions are done involuntarily each day. We do not need to think about breathing every hardly a(prenominal) seconds or make our heart beat constantly. This process keeps us wary also. Different nuclei are responsible for different tug functions accordingly (Sugerman, 2008, p. 278). The cerebellum is compose of gray and white matter, and its cortical approach is convoluted like the surface of the cerebrum. It is also divided by a central fissure into two lobes connected by vermis (Sugerman, 2008, 284). The cerebellum has many functions, it is in charge of reflexes, willing fine-tuning of motor control and for maintaining balance and posture through extensive unquiet connections with the medulla (Sugerman, 2008, 284). The little brain or cerebellum, receives instruction from the balance strategy of the inner ear, sensory nerves, and the auditory and visual music al arrangements. It is involved in the coordination of motor movements as well as basic facets of memory and learning, homeostatic control,.The interbrain has four major parts epithalamus, thalamus, hypothalamus, and subthalamus. The thalamus is in charge of relaying the cerebral 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).
