【Abstract】 The electron micrographs of ADVR in lizard Eumeces Chinensis are magnified and quantitatively analysed by means of an object and computer projection system.The results of survey show:The average thickness of presynaptic membrane in 70.3×10 -10 m;The average thickness of post synaptic membrane is 117 7×10 -10 m;The average width of synaptic cleft is 147×10 -10 m;The curvature of synaptic interface is (1.123±0.389)×10 -10 m,and the length of active zone is (3514.93±982.75) ×10 -10 m. The average diameter of hollow synaptic vesicles is (477.3±38.45)×10 -10 m;The average diameter of densce cored synaptic vesicles is (892±55.83)×10 -10 m.更多还原
