Structure of the Eye

1
Structure of the Eye

• Anterior Cavity smaller cavity contained
  between the cornea and lens, filled with aqueous
  humour
• Sclera white of eye acts as support and
  protection, very thick and connects to skeletal
  muscles
• Cornea transparent section of sclera

2
Structure of the Eye

• Ciliary Muscle muscles that pull on suspensory
  ligaments that control lens focus
• Iris pigmented smooth muscle that controls the
  size of the pupil as well as the amount of light
  that enters the eye
• Posterior Cavity large cavity filled with
  aqueous humour contained between the lens and
  retina

3
Structure of the Eye

• Choroid layer between the sclera and retina, has
  capillary network, delivers oxygen and nutrients
  to the retina
• Retina thin pigmented layer of tissue that is
  composed of cones and rods
• Optic disk or blind spot of retina where the
  optic nerve connects to the retina

Structure of the Eye

• Cones cells that conduct photo-chem reactions
  used for color vision. Cones are three colors
  red, blue, green
• Rods cells that conduct photo-chem reactions
  used for night vision
