The brain is a key component of the central nervous system. Due to its structure, the brain is categorized into both hemispheres of the brain, the brainstem and the cerebellum. The brain is the backbone and central part of the central nervous system. The brain fills our skull. What exactly is the function of the brain?
3st century medicine shows that the brain is divided into 1350 parts: the brainstem, the cerebellum and the brain, which in turn is divided into the right and left hemispheres. The hemispheres of the brain are the largest part of the brain and form a kind of barrier, covering the rest of the brain from the top. All elements of the brain structure occupy almost the entire volume of the skull, and their total weight in an adult is about XNUMX grams.
Brain – structure
The cortex of the brain is responsible for covering the brain. The folds that it creates as a result of wrinkles merge with each other, and as a result, the lobes of the brain form as a result of the fusion. Due to their arrangement, the lobes are classified as: parietal, temporal, frontal and occipital. The brain is also home to neuronal clusters, also known as cortical centers. The role of neuron clusters is to perceive external stimuli. The frontal lobe, on the other hand, is responsible for creating our thoughts. The movement center is also located in the brain. He is responsible for every move we make.
The brain also contains the speech center, also known as the Broca center. In the event of damage to the speech center, the body of the injured person is unable to perform properly coordinated movements that enable speech. Such persons, despite their ailments, are often able to move their lips and lips further. The temporal lobe is responsible for the sensation of hearing and speech. In the case of a violation of the sensory center of speech, the injured person, despite the fact that he hears, is not able to understand what the other person is saying to him. The parietal lobe, on the other hand, is responsible for feeling in the general sense of the word. The sight center is located in the occipital lobe. The brain is also the site of the endocrine gland. The size of the basal surface of the brain is similar to the size of the inner base of our skull. This is where these endocrine glands are located, and they are categorized into two types: the hypothalamus and the pituitary. This gland is responsible for the production of hormones, which then enter the blood.
The brain stem is an extremely important part of the brain. Responsible for key functions for the proper functioning of the body. The brainstem is home to the centers of breathing, regulating the heart, regulating our body temperature, regulating blood pressure, and the centers of sneezing, coughing and vomiting. It is worth adding that the brainstem consists of two elements: the midbrain and the medulla that connects to the spinal cord. Within these two elements, there are also reticulated formations responsible for regulating sleep.
The cerebellum is another part of the brain. Its location is the lower part of the skull. It is located right next to the brain stem. The task performed by the cerebellum is to coordinate movements and maintain balance. It is the cerebellum that allows us to perform more complex motor functions, such as swimming or cycling.
