组成神经系统的神经细胞形成错综复杂的网络,此网络在发育期间怎样建立起来以达到神经细胞之间有特异的连接方式,并使彼此之间能传导信息及传导给身体其他组织,这就需要每一神经细胞在其接触处“选择”适合于它与其他细胞特异连接的递质物质。神经细胞(或称神经元)与神经细胞之间,或神经细胞与身体其他组织(如肌和
The nerve cells that make up the nervous system form an intricate network. How this network is set up during development to achieve specific connections between nerve cells and to enable them to conduct and communicate information to other tissues in the body requires A neuron “chooses” at its point of contact for the transmitter substance that it is specifically linked to other cells. Nerve cells (or neurons) and nerve cells, or between nerve cells and other tissues (such as muscle and
