Study Notes
Sheep Eye Anatomy
-
Optic Nerve: Transmits visual information from the retina to the brain, crucial for processing images.
-
Sclera: The white outer layer of the eyeball, providing structure and protection; continuous with the cornea at the front.
-
Cornea: A transparent front layer of the eye, responsible for refracting light onto the lens; protects the eye from dust and pathogens.
-
Choroid: A vascular layer between the retina and sclera, supplying blood to the eye and containing pigment to absorb excess light.
-
Tapetum Lucidum: A reflective layer in the eye (more prominent in animals) that enhances night vision by reflecting light that passes through the retina back into the eye.
-
Iris: The colored part of the eye that controls the size of the pupil, regulates the amount of light entering the eye.
-
Pupil: The opening in the center of the iris that allows light to enter the eye; diameter changes in response to light levels.
-
Retina: The inner layer containing photoreceptive cells (rods and cones) that convert light into electrical signals for the brain.
-
Lens: A transparent, flexible structure that focuses light onto the retina, adjusting shape for near or distant vision.
