Moo-dified Vision
This infection can cause inflammation and swelling that could kill a cow.
What is conjunctivitis?
This protective structure is attached to the extraocular muscles.
What is the sclera?
What photoreceptor detects color?
What are the cones?
-itis means what?
What is inflammation?
What tools are used during the cow eye dissection?
What are scissors and forceps?
Name two animals (besides a cow) that have a tapetum.
What is a dog, cat, deer, raccoons, fox, ferret, goat, elephant, seal, shark, dolphin, owl, bat, lemurs, crocodile, alligator, spider, and some snakes?
This clear layer helps light enter the eye while protecting internal parts.
What is the Cornea
What is the choroid?
What causes "red-eye" in photos?
What is the light reflecting off blood vessels in the choroid?
This structure is removed first during the dissection.
What is conjunctiva?
What advantage do predators (like cats) with vertical pupils have?
What is better depth perception and focus on prey?
This muscular structure is responsible for controlling the shape of the lens.
What is the ciliary body?
What is the optic disc?
This is the X-shaped crossing point where optic nerves cross, allowing visual information from both eyes to be sent to the brain.
What is the optic chiasm?
This cut is made after puncturing the eye.
What is a frontal cut?
What lets them scan for predators while feeding?
This structure is produced by the ciliary body and nourishes the eye.
What is the aqueous humor?
What is the full name of the structure that allows animals to see in the dark?
What is the tapetum lucidum?
Why do humans not have a tapetum?
In the posterior end of the cow eye, where are the retina, tapetum, and choroid located relative to each other?
What is the choroid, tapetum, and retina (outermost to innermost)?
What does the shape of an animal's pupil usually indicate about its ecological role?
What are predators = vertical pupils, prey = horizontal pupils, arboreal/generalist animal = round pupil?
Name all three tunics with each structure
What are the Fibrous (cornea, sclera), Vascular (choroid, ciliary body, iris), and Neural tunics (retina)?
How does light travel through the eye to form an image?
Why does light enter the cornea, passes through the pupil, focused by the lens onto the retina, where photoreceptors change light into signals that travel through the optic nerve to the brain, where those signals turn into an image.
A small depression in the retina that's responsible for high acuity vision
What is the Fovea?
Arrange these structures from anterior to posterior:
Iris, Lens, Retina, Cornea, Choroid, Aqueous humor, pupil, Vitreous humor.
What is the cornea, aqueous humor, iris, pupil, lens, vitreous humor, retina, choroid?
