1. Conclusion The compression of optic nerves and optic chiasma is responsible for different types of visual field defects caused by saddle area tumors.

2. Chiasma (pl. chiasmata) A connection between homologous chromosomes seen during the prophase stage of meiosis.

3. The small branches seen anteriorly to optic chiasma in the chiasmatic cistern were almost always the branches of superior hypophyseal artery.

4. The chiasmata can slip off the ends of the bivalents, and thus chiasma frequency may be reduced by terminalization.

5. Conclusion The cause of lost vision was accidental injury of the optic nerve or the optic chiasma during...

6. Today, with the changing quickly computer technology and in-depth subjects chiasma, the traditional safety monitoring work is being endowed with much more new content.

7. The results indicated that both the number of rod bivalents and the number of pre-division bivalents increased markedly after radiation, while the number of bivalent chiasma tended to decrease.

8. Objective To provide morphological evidences for visual field defects caused by the compression of optic nerves and optic chiasma by saddle area tumors.

9. The analysis of chromosome behavior in miosis and frequency of bivalent chiasma at diakinesis of pollen mother cells of F1 hybrid plants, and the affinity extent were reported in this paper.

10. No difference was observed in chromosomal number, relative length and chiasma location.

11. It is of the first magnitude to strictly manage the yellow route of the section of a highway , especially at chiasma.

12. The axons from the nasal half cross the brain at the optic chiasma to join with axons from the temporal half of the other eye before passing into the lateral geniculate body.

13. Results Orbit tumor of a 21 year old young lady extends the encephalic and endangers the olfactory nerve and optic chiasma, even cause olfaction and visual acuity to be declined.sentencedict.com/chiasma.html

14. The sightseeing agriculture is take the agriculture as the foundation, one kind of type of chiasma emerging industry which the agriculture and the tourism unify.

15. Through the endoscope-assisted subtemporal keyhole approach, scopes between the optic chiasma and the ventral brain stem, from the mamillary body to the middle-inferior clivus can be well managed.

16. Certainly, elects specialized also to choose segmentations as far as possible, the type of chiasma, the practical specialty.
