human brain structure and function that are discussed in this article are located in the skull and consists of five departments, including the midbrain, intermediate, posterior, and elongated front.The average weight of the brain of adults is about 1.5 kg, and in newborns almost 400 grams.
human brain structure and function are determined by the capabilities of the body, forms the middle, rear, elongated and intermediate divisions.It is of great importance and the cerebral hemispheres, which distinguishes man from animals.From various departments come nerves that connect the brain with all the authorities and human receptors.With nerve brain analyzes and processes the feedback and external stimuli, and also generates a necessary response to them.The human brain, the structure and functions of its departments operate in a way that most effectively adapt to environmental conditions.By this arrangement, the process of coordinating the activities of all organs and tissues of the body, depending on various factors.
medulla oblongata is a continuation of the spinal cord.It carries the wiring and reflex functions.Outside it is covered with a white substance, which forms a conductive path for the activity of the brain.Its central part consists of gray matter, which is a group of neurons responsible for the parasympathetic nervous system.Medulla contains a center of cardiac activity, respiratory and vasomotor centers.He also is responsible for the unconditioned alimentary reflexes and protective reflexes.
hindbrain structure and functions which provide a reflex function, consists of the cerebellar pontine and medullary bridge.Over the medulla brain it has a bridge that contains the center of the facial and oculomotor nerve endings.Also pass through it pulses of the medulla oblongata in the upper parts of the brain.It coordinates the movement of the human body, as well as support its balance of the cerebellum.It consists of two hemispheres, and the central part and covered with gray matter.The most active development of the cerebellum occurs between 5 and 11 months of life.
Structure and function of human midbrain provide full processing auditory and visual information.This part of the brain consists of two legs that connect it to the intermediate and the medulla oblongata, and the roof, where there are centers visual and auditory stimuli.
Intermediate human brain consists of the thalamus, epithalamus, geniculate bodies and podbugornoy region (hypothalamus).He is responsible for the activity of the central nervous system.Thalamus coordinates sensitivity, facial expressions, gestures and other human emotions.The hypothalamus is responsible for the autonomic nervous system and provides metabolism, endocrine function, and also performs the coordination of sleep.Geniculate include visual and auditory centers.
human forebrain, the structure and functions of which are aimed at management of the entire body consists of hemispheres, which are connected to the corpus callosum.The cerebral cortex is covered with a special gray matter.Thanks to him, provided pathways for the signals from the nerve endings.Cora forebrain includes 6 different layers of nerve endings and divided furrows 4 functional parts: the frontal lobe, the parietal, temporal and occipital.The most advanced is the frontal lobe, which is separated from the central groove of the parietal lobe.In the frontal lobe accounts for about 50 percent of the entire mass of the brain.Cora is the basis of the mental state of a person.The right and left hemisphere are slightly different, with the result that the left hemisphere is responsible for abstract thinking, and the right - for the imaginative.
