| Abstract: | adult health ke'eqin fine-wool sheep were investigated to observe morphology location and cytoarchitecture of main nuclei of their pons.The results showed as follow:The length of dorsal cochlear nucleus was 4 6mm,and the cell density of the nucleus was 1950/mm 3,The nucleus consists of small oval cell,spindle cells and polyhedral cells,and there gional of cell arrangement was not obvious.The length of ventral cochlear nucleus was 4 8mm,and the cell density of the nucleus was 3041/mm 3.The length of nucleus of facial nerve was 6 7mm,and cell density was 855/mm 3,the most of the cell were polyhedral,and the nucleus may be divided into 5 subnuclei,of which the dorsomedial subnucleus,lateral subnucleus were dorsal side subnucleus are bigger and center subnucleus was smaller. |
