Flashcards in The Eye Deck (14):
1

Rods

  • Photoreceptors
  • React to low intensity light
  • Give rise to black and white vision

2

Iris

  • Pigmented structure suspended towards the centre of the eye
  • Controls the ammount of light that enters the eye
  • Changes the size of the pupil

3

White connective tissue that makes the outside of the eyeball

Sclera

4

The lens of the eye

  • An elastic, transparent, biconvex structure
  • Changes shape
  • Refracts light from near and far objects
  • Foms a clear image on the retina

5

An organ formed as a result of the concentration of receptors with the same function

sense organ

6

Dark, pigmented layer of the eye that provides the cells with oxygen and nutrients

choroid

7

Involuntary muscles that cause the curvature of the lense to change during accomodation

ciliary body

8

Cones

  • Photoreceptors
  • React to high light intensities
  • Give rise to bright, sharp, colour vision

9

conjunctiva

  • The mucus membrane that covers the front of the eye
  • contains pain receptors
  • Results in the blink reflex

10

The receptors in the eye that repond to light stimuli

photoreceptors

11

The layer of the eye that contains photoreceptors

Retina

12

suspensory ligaments

Structures attaching ciliary body muscles to the eyes lens

13

Front transparent part of the eyeball, more convex than the rest of the eyeball

cornea
