The brain is the main part of the central nervous system and is located in the cranial cavity. The brains of humans and mammals are particularly developed and can be divided into three parts: the brain, the cerebellum and the brainstem. The brain have many nerve nuclei or nerve centers distributed, and a large number of nerve fiber bundles pass through to connect the brain, cerebellum and spinal cord. The brain includes the telencephalon and the diencephalon. The telencephalon includes the left and right cerebral hemispheres. The telencephalon is the main part of the high-level nervous system of the vertebrate brain. It consists of the left and right hemispheres and is the largest part of the human brain. It is the high-level nerve center that controls movement, produces feelings and achieves advanced brain function. The main function of the cerebellum is to coordinate the movement of the skeletal muscles, maintain and regulate muscle tension, and maintain the balance of the body.
The weight of the brain accounts for 2% to 3% of body weight, but the blood flow required is 15%-20% of the cardiac output. The average weight of the newborn fetal brain is 390 grams, and the brain develops rapidly after birth. By the age of 3, the average is 1100 grams. The adult's brain weighs about 1400 grams, which means that 80% of the weight of a person's brain is formed before the age of 3. Protein is crucial for the development of infant brains. The weight of the brain accounts for 2% to 3% of body weight, but the blood flow required is 15%-20% of the cardiac output.
Here is the brain lapel pins: many silver metal lines like the interval, pink colors as brain organ, the red area seems the blood, some glitter in it.
