QuestionAnswer
Photoreceptors extend all the way out to _________ in the retina Ora Serrata
How many layers make up the retina 10
List the 10 layers of the Retina 1.Retinal pigmented epithelium. 2.Layers of Rods (low green) & Cones (red, green, blue). 3.Outer Limiting membrane. 4.Outer nuclear. 5.Outer plexiform. 6.Inner Nuclear. 7.Inner plexiform. 8.Ganglion Layer 9.Nerve Fiber Layer. 10.Inner Limiting me
3 functions of the Retinal pigmented epithelium 1.Absorb stray photons. 2.phagocytose extruded cells from rods & cones. 3.Part of BL retina barrier.
What makes up the outer limiting membrane layer? Muller cells **Act as the glial cells of the retina for physical support.
What layer contains the photoreceptor nuclei (rods and cones) Outer Nuclear layer
What layer contains the synapses b/w the photoreceptors and the bipolar interneurons? Outer Plexiform layer
What is contained within the Inner Nuclear layer? Nuclei of: 1.Horizontal cells. 2.Muller cells. 3.Bipolar neurons. 4.Amacrine cells.
Where does visual processing begin? with the AMACRINE CELLS: 1.edges, 2.Contrast, 3.motion.
What contains the synapses b/w the bipolar interneurons + Amacrine cells and the retinal ganglion? Inner plexiform layer
What layer contains the retinal ganglia Ganglion layer. **Decreases in thickness towards the periphery.
What forms the Retinovitrial boundary? Inner Limiting membrane.
Compare what happens when light hits the center of an On-center cell Vs Off-center cell ON: Light causes depolarization and Inc signals. OFF: light causes hyperpolarization and dec signals.
Compare what happens when light hits the surrounding of an On-center cell Vs Off-center cell ON: light causes hyperpolarization and dec signals. OFF: light causes depolarization and Inc signals
Where do the Blood vessels run along after the enter the optic disc? Inner limiting membrane
Where is the highest visual acuity? Fovea Centralis within the Macula lutea. **Avascular.
What does a fuzzy optic disc indicate Pressure change: 1.Bulging into eye: Inc intracranial. 2.Bulging out of eye: Inc intraocular.
What happens to the 10 retinal layers at the optic disc? They disappear. **creates a blind spot.
What offsets the blindspot created by the optic disc? Fovea centralis **Inc visual acuity b/c the inner layers are gone, leaving the photoreceptors in the Outer nuclear layer which is thickened here.
2 main glands of the eye 1.Lacrimal (tears). 2.Tarsal (oily).
Pathway of tears from lacrimal gland 1.Lacrimal gland. 2.Conjuctiva Fornix. 3.Lacrimal Lake. 4.Lacrimal puncta. 5.Lacrimal canaliculli. 6.Lacrimal sac. 7.nasolacrimal duct. 8.inferior nasal concha.
Tract the fovea and gaze: SR Fovea: down. Gaze: superior, medial.
Tract the fovea and gaze: IR Fovea: Up. Gaze: inferior, medial.
Tract the fovea and gaze: SO INTORSION: Fovea: Superior, medial. Gaze: Inferior, lateral.
Tract the fovea and gaze: IO EXTORSION: Fovea: Inferior, medial. Gaze: Superior, lateral.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
