SYNAPSE STRUCTUR AND SYNAPSE STRUCTUR AND SYNAPTIC TRANSMISSION SYNAPTIC TRANSMISSION Dr. Dr. Saswati Saswati Parua Bajkul Bajkul Milan Milan Mahavidyalaya Mahavidyalaya Parua ( (Mondal Mondal) )
Synapse Synapse The term synapes was first introduce by Sherrington C.S. as the contiguity. Synapes is the junction between two neurones.
Classification Of Synapse Classification Of Synapse Anatomical classification Functional classification
Anatomical Classification Anatomical Classification
Functional Classification Functional Classification
Structure of chemical synapse Structure of chemical synapse
Function Of Synapse Function Of Synapse Main function of synapse is to transmitted the impulse i.e. action potential from one neurone to another .However , some of the synapse inhibit these impulses .So ,impulse are not transmitted to the post synaptic neurone . On the basis of function, synapse are divided into two types - 1. Excitatory synapse 2. Inhibitory synapse
Excitatory Function Excitatory Function
Inhibitory Function Inhibitory Function Inhibition of synaptic transmission is classified into 5 types :- 1. Postsynaptic or direct inhibition 2. Presynaptic or indirect inhibition 3. Negative feedback 4. Feedforward inhibition 5. Reciprocal inhibition
Properties of synapse Properties of synapse One way conduction Bell Magendie law Synaptic delay Fatigue Summation Electrical property
