Visual system: receptors
retinal receptor cells, rods, cones
receptive organ
structure of the eyeball
connections back to the CNS
optic nerves and pathways of crossover at the optic chiasm
processing center
lateral geniculate nucleus, optic radiations
interpretation of a the vis system done by
primary and secondary visual cortices
eye layer - posterior to the ora serrata
choroid, neural retina, pigmented epithelium
middle layer - between the ora serrata and the limbus
ciliary body, ciliary muscle, and lens
layer anterior to the limbus
cornea, iris, pupillary dilator and constrictor muscles, conjunctiva
there's more
anterior, posterior chambers, production and flow of aqueous humor, schlemm canal, vitreous humor, optic dics, fovea, central artery of the retina, macula, fovea
sclera is continuous with...
the dura mater
sclera made of
collagenous fibers
what zone does the limbus become the sclera
limbus
middle layer is called
uvea
what's in the uvea
choroids posteriorly, and the ciliary body and stroma of the iris
innermost layer is from?
outgrowth of CNS
innermost layer is two layered - why?
oreflects it origin from the infolding of the optic cup
anterior of the innermost layer is serrated - what' it called
ora serrata
inner layer of the retina is
neural retina
outer layer is called
the pigmented layer
What does this have to do with detached retina
the two layered set up in the retinal gives rise to the detachment of one from the ohter
Eyes develop from 4 sources...
neuro ectoderm, surface ectoderm of the head, mesoderm between the first two layers, and neural creat cells
neuroectoderm of the forebrain produces?
retina, post layers of the iris, optic nerve
surface ecto?
lens, corneal epithelium
mesoderm?
fibrous and vascular coats
neural rest cells produce
choroid, sclera, corneal endothelium
eye dev first evident what week
4th
what's 1st?
optic grooves appear in the neural folds at the cranial end of the embryo
Next?
optic grooves evaginate- form optic vesicles
What do the optic vesicles do?
Project from the wall of the forebrain into the adjacent mesenchyme
formation of the optic vesicle is induced by?
mesenchyme adjacent to the dev brain.
