Structure of the Cochlea in Myospalax Cansus

Sanning electron micoscope research about Myospalax cansu’cochlea.The results show that the cochlea structures between Myospalax cansu and other mammals are similar,it also have a typical screwy structure,and it have three point five circles aggregately.The helix ganglions are clear,which include big deeply dyed cells and small shallowly dyed cells,from the bottom to the top of the cochlea,the number of the helix ganglions gradually increases.Tissue treated with scanning electron microscopy,in Myospalax cansu’ cochlea,the inner hair cells are arranged in a line,and there are about thirty stereocilia on the top of inner hair cells,they are arranged in linear.Outer hair cells are arranged in three rows,there are about four rows stereocilia on every outer hair cell,and there are about thirty stereocilia every row,about one hundred and twenty stereocilia every bundle,they are arranged like a C These stereocilia arranged orderly,and the length of the stereocilia heightened from inside to outer side of the stereocilia bundle gradually.
