突触是指一个神经元与另一个神经元或肌肉相连接的部位,是神经细胞的一种特化连接,它可分为化学性突触和电突触,通常所说的突触是指化学性突触。突触是近几年各地高考的高频考点,也是考生失误高发区。下面通过探秘突触结构,剖析高频考点,引领知识运用,提升解题能力。考点探秘考点一:突触的结构电镜下,突触由三部分组成:突触前膜、突触间隙和突触后膜(见下图)。突触前膜指
Synapse refers to a neuron connected to another neuron or muscle sites, is a specialized neuronal connections, which can be divided into chemical synapses and electrical synapses, commonly referred to as synapses refers to Chemical synapse. Synapses in recent years around the college entrance examination of high frequency test sites, but also a high incidence of errors candidates. Following the exploration of the synapse structure, analysis of high frequency test centers, leading the use of knowledge to enhance the ability to solve problems. Test points Quest a test site: the structure of synapses Electron microscopy, the synapse consists of three parts: the presynaptic membrane, synaptic cleft and postsynaptic membrane (see below). Synaptic membrane means
