Human brain - structure
From birth, the brain is constantly growing. We acquire more life experiences, remember more and are constantly learning new things. How much does the human brain weigh? In an adult, the brain weighs around 1350 grams, which is slightly more than a packet of sugar. This comparison, moreover, is not coincidental, as the main energy source of this organ is sugar. What does the human brain look like? The researchers saw the brain's resemblance to a walnut. Numerous curves and furrows are also observed on its surface, making the brain look wrinkled. Such an appearance, by the way, is no accident. The packing makes it able to accommodate more neurons, which form complex neuronal networks responsible for regulating vital functions. The average brain contains around 100 billion grey cells, however, a single neuron does not have the capacity to divide. As we age, the number of neurons decreases or dies, which is associated with neurodegeneration processes and the occurrence of ailments such as Alzheimer's disease.
Anatomically, the central nervous system (also known as the central nervous system) consists of the brainstem, spinal cord, cerebral hemispheres, cerebellum and the meninges. The human brain is divided into two halves, the right and left, both covered by the frontal, parietal, temporal and occipital lobes.
