人脑是心理活动的器官。要了解幼儿的心理特点,首先要了解脑的结构和机能,了解幼儿神经系统发育特点。一、脑的结构人脑大约由140—150亿个神经细胞组成。每个神经细胞有细胞体和细胞突起两部分构成。突起有两种:树状突和轴状突。一个神经细胞的轴突末枝分梢同另一个神经细胞的胞体或细胞的突起相接触。神经系统就是依靠这种神经元的联系进行有机的活动。
The human brain is an organ of mental activity. To understand the psychological characteristics of young children, we must first understand the structure and function of the brain to understand the development of children’s nervous system features. First, the structure of the brain Human brain composed of about 140-150 million nerve cells. Each nerve cell has a cell body and cell protrusions in two parts. There are two protrusions: dendrites and axons. The axon terminal branch of one nerve cell contacts the protrusion of the cell body or cell of another nerve cell. The nervous system relies on this neuron’s connections for organic activity.
