The morphology and spatial arrangement of astrocytes in the optic nerve head of the mouse.

30 Aug 2009 We evaluated the shapes, numbers, and spatial distribution of astrocytes within the glial lamina, an astrocyte-rich region at the junction of the retina and optic nerve. A primary aim was to determine how the population of astrocytes, collectively, ... Read more...

Endoscopic approaches to the orbit: a cadaveric study.

29 Jul 2009 INTRODUCTION: The role of the endoscopic management of lesions located in the anterior cranial fossa and skull base continues to expand. MATERIALS AND METHODS: An endoscopic anatomic study was conducted on cadaver specimens. 10 orbits from 5 ... Read more...

Low-hemorrhage-risk surgical approach to expose the optic nerve in rabbits without bony removal and rectus resection.

29 Jun 2009 OBJECTIVE: A low-hemorrhage-risk surgical approach to expose the optic nerve (ON) in rabbits through the orbital process of the frontal bone without removal of the bony orbit and resection of the rectus muscle was explored and assessed in this ... Read more...

Technical information about 'Optic Nerve'

Definition: The 2nd cranial nerve. The optic nerve conveys visual information from the retina to the brain. The nerve carries the axons of the retinal ganglion cells which sort at the optic chiasm and continue via the optic tracts to the brain. The largest projection is to the lateral geniculate nuclei; other important targets include the superior colliculi and the suprachiasmatic nuclei. Though known as the second cranial nerve, it is considered part of the central nervous system.
