| Flechsig's fasciculi | Fasciculus anterior proprius and fasciculus lateralis proprius. See: fasciculi proprii. (05 Mar 2000) |
|---|---|
| longitudinal pontine fasciculi | The massive bundles of corticofugal fibres passing longitudinally through the ventral part of pons; they are composed of corticopontine, corticobulbar, and corticospinal fibres. Synonym: fasciculi longitudinales pontis, longitudinal pontine bundles. (05 Mar 2000) |
| vaginae nervi optici | Sheaths of the optic nerve, formed by extensions of the central meninges. See: internal sheath of optic nerve, external sheath of optic nerve. (05 Mar 2000) |
| radix lateralis tractus optici | The larger division of the posterior end of the optic tract that terminates in the lateral geniculate body. Synonym: radix lateralis tractus optici. (05 Mar 2000) |
| radix medialis tractus optici | The smaller division of the posterior end of the optic tract that disappears under the medial geniculate body. Synonym: radix medialis tractus optici. (05 Mar 2000) |
| rami tractus optici | The optic tract branches, branches of the anterior choroid artery to the optic tract. (05 Mar 2000) |
| papilla nervi optici | The portion of the optic nerve seen in the fundus with the ophthalmoscope. It is formed by the meeting of all the retinal ganglion cell axons as they enter the optic nerve. Because the retina at the optic disk has no photoreceptors there is a corresponding blind spot in the visual field. (12 Dec 1998) |
| pars intracanaliculus nervi optici | <anatomy, nerve> The part of the optic nerve lying within the optic canal. Synonym: pars intracanaliculus nervi optici. (05 Mar 2000) |
| pars intracranialis nervi optici | <anatomy, nerve> The portion of the optic nerve between the optic canal and the optic chiasm. Synonym: pars intracranialis nervi optici. (05 Mar 2000) |
| pars intralaminaris nervi optici | <anatomy, nerve> The portion of the optic nerve as it passes through the lamina cribrosa of the sclera. Synonym: pars intralaminaris nervi optici. (05 Mar 2000) |
| pars intraocularis nervi optici | <anatomy, nerve> The part of the optic nerve within the eye; it is divided into intralaminar, postlaminar, and prelaminar parts. Synonym: pars intraocularis nervi optici. (05 Mar 2000) |
| pars orbitalis nervi optici | <anatomy, nerve> The part of the optic nerve between the eye and the optic canal. Synonym: pars orbitalis nervi optici. (05 Mar 2000) |
| pars postlaminaris nervi optici | <anatomy, nerve> The portion of the optic nerve posterior to the lamina cribrosa of the sclera. Synonym: pars postlaminaris nervi optici. (05 Mar 2000) |
| pars prelaminaris nervi optici | <anatomy, nerve> The portion of the optic nerve anterior to the lamina cribrosa of the sclera. Synonym: pars prelaminaris nervi optici. (05 Mar 2000) |
| circulus vasculosus nervi optici | <anatomy, nerve> A network of branches of the short ciliary arteries on the sclera around the point of entrance of the optic nerve. Synonym: circulus vasculosus nervi optici, circulus arteriosus halleri, circulus zinnii, Haller's circle, Zinn's corona, Zinn's vascular circle. (05 Mar 2000) |
