BS - Layers of the Retina - Week 1 Flashcards
What is the innermost layer of the eye?
Retinal pigment epithelium
What comes after the retinal pigment epithelium? Which 2 cell types are associated with it?
Photoreceptor layer
Rods and cones are here
What comes after the photoreceptor layer?
Outer limiting membrane
What comes after the outer limiting membrane and what can be found here?
Outer nuclear layer
Nuclei of the photoreceptors are here
What comes after the outer nuclear layer and what can be found here?
Outer plexiform layer
Synapses between photoreceptors and bipolar/horizontal cells can be found here
What comes after the outer plexiform layer? The nucleus of which 3 cell types are associated with it?
Inner nucleus layer
Horizontal cell, bipolar cell, and amacrine cell nuclei are here
What comes after the inner nucleus layer and what can be found here?
Inner plexiform layer
Synapses between horizontal, bipolar, and amacrine cells to the ganglion cells can be found here
What comes after the inner plexiform layer and what cell type is associated with it?
Ganglion cell layer
Ganglion cells are here
What comes after the ganglion cell layer and what can be found here?
Nerve fibre layer
Ganglion cell axons are here
What comes after the nerve fibre layer?
Inner limiting membrane
Which layer does light reach first?
Inner limiting membrane
What do rod cells do and what is their peak density?
Rods are resonsible for greyscale light detection, and arent colour sensitive, needed for night vision. Peak density is at 18 degrees
Cones needed for day vision, and are colour sensitive, peak density is central
What do ganglion cells do and what do their axons form?
Output cell of the retina, axons form the optic nerve.
