How is mammalian eye structurally adapted to it's function?

Question

Structural adaptation of the mammalian eye to it's function

Answer 1

Structural adaptation of a mammalian eye to it's function;

• Has sclera/sclerotic layer that contains inelastic (collagen) fibres to protect/maintain shape of the eye.
• Cornea is transparent to allow light to pass through or curved to reflect light toward retina.
• Conjuctiva, (thin) epithelium to protect the cornea.
• Has choroid which is rich in blood vessels/highly vascularized to supply the retina/eye with nutrients/ oxygen/remove metabolic waste.
• Has lens that is transparent to allow light to pass through.
• Iris has redial and circular muscles to alter the size of the pupil/control amount of light entering the eye.
• Retina contains cones and rods(photoreceptors) to perceive light/where the image is focused/formed.
• Has optic nerve sensory neurons/nerve cells that transmit impulses to the brain.
• Fovea has numerous cones (only) for accurate vision/high visual acuity.
• Pupils a hole/aperture/opening on the iris that lets in light.
